Inexplicably dropped into a vast new world, the trio is greeted by Kurousagi, who explains that they have been given a once-in-a-lifetime chance to participate in special high-stakes games using their abilities. In order to take part, however, they must first join a community.

- Sakamaki Izayoi The main character of this work. A 17-year-old boy who is one of the problem children invited to the world of Little Garden since the 2000s. His maiden name was Saigo. His parent is the creator of the third perpetual motion machine, the nanomachine "Third Class Astral Particle Body", and Homura Saigo is his younger brother. He was wearing headphones with a flame mark from Homura's “Crescent moon” series, but they broke in Part 1 Volume 3.

A hero who obtained the power of the third perpetual motion machine to prevent the world from being destroyed by the hands of a nation or organization that acquired the development method of the third perpetual motion machine. If you save the world indirectly, save it as a developer of the third perpetual motion machine, and if you save the world directly, save it as a test subject of the third perpetual motion machine. In the case of Izayoi, it is the latter, and the original source of the stellar particle body is embedded in the fetus.

Originally, he was not supposed to come to Hakoniwa and even have a connection with Kintojaku, so he was supposed to be born in the future, but due to the interference of the former "No Name" in human history, his birth time changed greatly, and Kintojaku and others became new. When he tried to create a group of gods and support "original candidates", he dug up the possibility of Sakamaki Izayoi and became mankind's "original candidate" in the midst of that interference. Kinhijaku calls his existence the “Last future of Embryo” and describes him as the strongest “original candidate”. The person himself says it's a coincidence, but Croix believes that only a human named Sakamaki Izayoi has the potential to save the world in some way. It is said that it was chosen as an original candidate because it had such a shape, and the law of cause and effect is reversed in Izayoi's bounty. A boon blessed because it is promised to save the future, not a boon obtained for saving the past  . At the stage when it was decided that Izayoi could be summoned to the miniature garden, Homura Saigo was created as a spare and agent of Gyakukai Izayoi in order to correct history.

Because of his life in the "Canary Family Home", he takes care of younger people, and dislikes being wielded with great power over weak beings like children. Only unconditionally kind to those who cannot stand up for themselves, such as those who are socially weak or those who are socially in a bad position. Even among the elite "no-names" in close combat, it has outstanding fighting ability. In battle, he always puts himself on the front line and tries to protect his comrades, but in addition to worrying about his comrades, it also stems from his inability to trust them moves and throws objects at the speed of the third universe, fists with the physical strength to crush mountains and rivers, nullifies all benefits other than physical interference, a strong body that can withstand attacks that would normally cause instant death, and the power to crush stars. It can display multiple powerful powers, such as emitting a pillar of light, but Izayoi still hasn't fully mastered "unidentified", and even the aforementioned power is only a part of her original power. it is revealed. He has received various gifts, including Mizuki seedlings, but these are mostly provided as shared materials for the community. The gift card was only used to carry Mizuki's seedlings and to evacuate Snow White.

In terms of intelligence, he is one of the top class members of "No Name" and is in the rank of Jin's staff, and with that knowledge, he is often the first to reach the secrets of the Little Garden and the clearing conditions of the gift game. He is quick to calculate risks, but he is willing to take a certain amount of risk in order to enjoy the gift game.

When he was a baby, he was kidnapped by Kinshijaku and left anonymously in a children's facility, where he was tormented by the world's conflicts due to his too-powerful grace, and was forced to live a life of loneliness and doubts about his monstrous nature. He visited 24 welfare facilities and 31 adoptive parents and was arrested 21 times for the cover-up crime of the adopter. He met Kinitojaku when he played a game where he was betting on, and became an adopted child. After being adopted by Kinitojaku, he traveled around the world, eventually being invited to the "Canary Family Home" that Kinitojaku made for Izayoi. After the death of Kinshijaku, she participated in the last game left in her will and found the answer, but battled in the space created by Croix Baron as a "bonus stage", and finally Destroyed the space with a pillar of aurora and escaped. He then wakes up and decides to go to the Little Garden of his own accord, opening his invitation and being summoned to the Little Garden. 19 years and 9 months in the second part "Last Embryo". As a qualification to participate in the Second Solar Sovereignty War, he has a lion in his hand and has become a body that cannot be cut with a knife, but he has only three months left as a minor, which is the qualification to participate.

The author cites him as one of the characters that are easy to move, and he is particular about the lines. The color of the gift card is cobalt blue.

Abilities
It has been stated that Izayoi is a very competent fighter and also has amazing reflexes and potential. Saurian Demon King once remarked that Izayoi had the potential to be an experienced martial artist with his skills. In Last Embryo 2, when Bull Demon King managed to smash Izayoi with a pole, Izayoi immediately blocked and kicked it off his hands timely. Izayoi also had shown an arm-locking technique when he tried to pin Bull Demon King to the ground and in near the end of the fight, he threw Bull Demon King away by grabbing his horns, making him crash into several maze wall layers, Bull Demon King remarked that he didn't expect Izayoi finally got some martial art skills. Up to now it's still unknown how Izayoi got them after 3 years of timeskip but its implied Kouryuu may have taught him.

Izayoi is incredibly intelligent. He has created plans to help the No Names in both battle and commerce. Izayoi has shown that he is knowledgeable in religions, fairy tales and mythologies, having easily identified the [Perseus] artifacts, solved the riddle of the Pied Piper of Hamlin, and identified constellations and asterims. When Izayoi is left behind to stall for time against Azi Dakaha, Asuka remarked that without him, they cannot even come up with a proper plan of attack. {|
 *  「GIFT」 
 * 《Code: Unknown》 - Not much is known about his ability as the Gift Card, a fragment of Laplace, could not categorize his ability and so named it [Code: Unknown]. Despite this, he seems to know his power well, being able to gauge whether or not he can take an opponent. He can defeat those blessed with [Divinity] such as a water god and Weser, deflect a lance attack from the weakened Leticia, stop a sword attack from Laius, who is a descendant of the hero Perseus, with one finger, and defeat the Kraken and Graea sisters, monsters that appeared in the legend of Perseus, with ease. Many people who have seen him fight have realized that his power is capable of destroying gifts. Black Rabbit also stated that his gift has the power to destroy heaven and earth, and later with a statement by Baron that it could even destroy the stars. This is shown during his battle with Algol and Black Percher, where he easily deflected their attacks. The force he emits behind his strength and speed is described in the Light Novels to be of the Third Cosmic Velocity or even faster than that.

This is shown during his battle with Algol and Black Percher, where he easily deflected their attacks. The force he emits behind his strength and speed is described in the Light Novels to be of the Third Cosmic Velocity or even faster than that.


 * Supernatural Strength: This seems to be the main function of Izayoi's Gift as it grants him immense strength. He uses his strength to throw objects at the 'Third Cosmic Velocity', run on walls by digging his feet into them, and even compress Leticia's lance into a ball by simply punching it. Back when Izayoi fought Baron La Croix before he got summoned to Little Garden, Izayoi could lift the entire building and throw it at him with no effort. In Volume 4, Izayoi easily defeated an army of Celtic Titan. Izayoi also could keep up with Saurian Demon King in Volume 5, as both of them neatly matched against each other though it was quite difficult for Izayoi because at that time he still didn't have martial art skills. When Izayoi knew His Highness was the one that injured Black Rabbit, in anger he beat him so violently that His Highness couldn't protect himself for a moment before his company came to save him. In Volume 7 both Izayoi and His Highness got a re-match at the Kouen City, His Highness admitted that Izayoi was stronger than him even though that Izayoi didn't feel any different from the powers of their fists. The punches of Izayoi were strong enough to destroy mountains and rivers, split the oceans or seas, on par with planetary crustal movement, and even shake the stars. As seen in Volume 8 when he has thrown hundred of punches that could shake stars on Azi Dahaka at the Third Cosmic Velocity, thus overwhelming him for a short amount of time before he put up his Aurora Pillar.
 * Enhanced Perception: Izayoi possesses an exceptional sixth sense, easily signaled out Fores Garo's henchman in Episode 3 and Leticia's presence when she was hiding outside the window in Episode 4.
 * Supernatural Speed: His speed is said to be on par with Black Rabbit, who is mentioned to be part of the fastest species in Little Garden. However, his speed is different from hers as he is able to retain that speed as shown when he blocked an attack meant for Black Rabbit, returned her safely to a rooftop and proceeded to return to fight Black Percher. He was fast enough to leave his afterimages, as seen in volume 5 when battling the Saurian Demon King and in volume 6, when chasing the Demon King of Confusion at Kouen City. If Izayoi were to put his full strength behind his every step, the residential structures that weren’t stable enough would most likely be blown away.
 * Supernatural Durability: Izayoi has been shown to be rather durable, being the only one out of the three problem children to not need a Gift of Protection to survive his fights and take on powerful attacks without being injured. It took Weser to double his power and possessing [Divinity] to only injure Izayoi and even then the injury did not even slow Izayoi down. However, his durability isn`t invincible, he's shown to be rather weak against bladed weapons wielded by a strong enough individual, and he suffered quite a bit during his fight against Saurian Demon King. In his battle with Azi Dakaha, Izayoi was stabbed through his abdomen and had his organs punctured. It should be noticed that when Izayoi's Aurora Pillar made contact with Azi Dahaka's [Avesta], he barely survived the force of impact, though Azi Dahaka later explained that their powers canceled each other out so that Izayoi could survive the blast. After his fight against Azi Dahaka, all the bones and the muscles in his body were minced.
 * Supernatural Stamina: During the fight with Azi Dahaka, although Izayoi received a lot of injuries and therefore his stamina almost ran out after the fight with His Highness, he was still able to fight with every bone and muscle in his body almost completely chopped up and crushed. Izayoi was the first one that held back Azi Dahaka for the others to run away even though he was already on the verge of his death.
 * Supernatural resistance: Based on his ability that allows him to negate and destroy Gifts, Izayoi has resistance to supernatural powers. Several examples include when Izayoi was totally immune to Ratten's mind control music in volume 2, Baron placed a Death Curse on Izayoi but it never took hold of him in volume 3, and when Demon King of Confusion stopped time in all of Kouen City and its residents, but Izayoi was completely unaffected in volume 6.
 * Aurora Pillar (fanmade name) - A power that revolves around creating a light construct in the shape of a small pillar which then enlarges to the point of reaching skyward, he then swings it at his enemy. This is the true manifestation of Izayoi's power to destroy Gifts. Its power could defeat Divine Spirits, eliminate all of the stars in the night sky and annihilate everything in the material world. He has used it for four times: to destroy the pocket dimension Baron La Croix created, to destroy the huge dragon's heart, in his fight against Azi Dakaha - when the Aurora Pillar made contact with the [Avesta] created a vortex with power comparable to the collison between stars that could destroy All Creation and their clash reduced more than half of a volcano peak to nothing more than subatomic particles, the force unleashed from Aurora Pillar capable of absorbing the light of the stars and pierce through the veil of Little Garden, and finally in Volume 11 with the help from Baron La Croix, he erased Maxwell Demon Lord by his Aurora Pillar with only one shot. His Highness described it as a "Another Cosmology", the secret techniques of the pantheons of Gods to construct their own worlds - universes. Izayoi also made a compliment by himself that his Aurora Pillar is shape of a possessing cosmology of humanity. It has been hinted from Volume 2 when Izayoi managed to unleash his full power against Black Percher after she mocked Izayoi that he didn't have enough strength to destroy stars but Black Rabbit stopped him due to the plan and in Volume 5, during the fight between him and Saurian Demon King that if Izayoi used this trumpcard, he would not be able to control it enough to let Saurian survive the hit, it also should be noted that when Izayoi put up his Aurora Pillar even Azi Dahaka got shocked after saw it and he had to activated his [Avesta] to counter him, making the Aurora Pillar is extremely powerful and very dangerous even for the strong Demon Lords. Only the like of His Highness or Azi Dahaka in which they also possessed "Another Cosmology" like Izayoi could match against his Aurora Pillar.
 * Grass Bracelet - A bracelet made of grass. It gives the owner the ability to talk to griffins. Sala gave this to Izayoi to let him communicate with Gry during the assault upon the huge dragon in the Underwood arc.

Abilities
Yō has shown to be a gifted individual and a rather fast learner, being able to pick up on Izayoi's logic applying skills and use them to solve the Gift Game of Volume 4. She has also shown to understand the phylogenetic tree greatly to be able to combine animal DNA to form various combinations in order to fight.

Yō has shown to be a rather skilled combatant, being able to use her powers to even defeat physically superior foes, such as Graiya, Maxwell, and simultaneously 2 of the Two-Headed Dragon "Clones" of Azi Dakaha's blood. {| class="mw-collapsible mw-collapsed" data-collapsetext="Hide" data-expandtext="Show" style="width:100%; background-color:white; margin-top:1em; border:1px solid black; border-radius:10px; font-size:100%; text-align:left;" ! width="100%" align="left" style="background:#10a9db; border-radius: 7px;" | 《Problem Child (Main Character #3)》 A 15-year-old girl, Asuka is the heiress from a rich family that owns a financial company. Originally, she lived in a time period after a war (presumed to be WWII) while attending boarding school. Who is one of the problem children, she was invited to the world of miniature gardens shortly after the war. Ever since she came to Hakoniwa, she has been wearing a red dress on a daily basis. She is Kuon Ayato's twin sister who died before it was decided which one was her older sister or younger sister. In her original world, she was the daughter of a conglomerate, and was almost guaranteed happiness in the future. For her, there are two places where she lives, her parents' mansion and the girls' dormitory, and she doesn't know the lifestyle of Japanese people of the same era. She went to school until she was ten years old, and although it was a strict place, she had her friends and was reasonably trusted by her teachers. She didn't even get along with her relatives, and she was a top candidate for the head of the family. However, she is disgusted with her relationships and her unchanging daily life, where her own gifts make everything her own, and she decides to go to the world of sandplay.

Born into a family that has passed down nearly 10 generations of descendants by a divine spirit, members of the former "No Name" who were sent to the outside world lend their strength to grow into a large financial conglomerate called the "Kuon Zaibatsu", specializing in the prosperity of commerce. The blood of those who possessed the blessings mixed in various ways, and by receiving the faith to wish for a savior in the era immediately after the defeat, he was born with a spiritual identity that can be called a demigod spirit. This is why Asuka's gift specializes in "giving" compared to the other two. Originally, it was supposed to manifest as a Divine Spirit, but due to the Divine Spirit's bounty and the body becoming twins, Asuka gained the Divine Spirit's bounty. A living god who possesses the deity of the imperial family, which was vacated by the blood of the imperial family and the human declaration.

She is noble but naive, and has a personality that attracts devils. Don't be stubborn, listen to the other person and try to have a conversation about what you don't know. That's why I clearly assert that I don't know what I don't know. Because he grew up in a harsh era, he is interested in small things in an open sand garden, and is easily attracted to girlish things. . Although he has a lot of pride, he is by no means arrogant, and has the flexibility to accept the opinions of others.

In Part 1, the physical abilities are normal humans, and in battle, he mainly uses "Dean" to fight, but "Almatia's Citadel", which was created and obtained with the technology of "Will o' Wisp", and "Hameln's wind flute", he began to use jewels with benefits such as ignition and cooling.

During the Battle of Azi-Dakaha, he led the entire army in a war of attrition. After the duel with Kuon Saicho, he set off in search of his no-name comrade who was sent to the outside world. The author said that he likes hard-working characters, and listed him as one of his favorite characters. The color of the gift card is wine red.

Abilities
A source of insecurity that she is physically the weakest among the three problem children, having no outstanding physical abilities like Izayoi and Yō, but her talent of how to hold and control financial in No Name Community are great, that even Izayoi impressed and also his strategy are the same as Izayoi standard of Intellect. Asuka has proven to have some skill in using the sword after the defeat of Galdo. She summoned the sword when forced to fight, using it against the rats that attacked her and Ratten.

The red dress with bows she receives from Kurousagi (Black Rabbit) has an "aura of protection" which makes it suitable for fights. She herself states that it is "easy to move in."
