Character
The main character of this work. In his previous life, he was an office worker in his 20s living in modern Japan. As a result of crossing a red light crosswalk while thinking, he is killed in a traffic accident caused by being hit by a car. When he was a baby, he was attacked by a monster, and all the family-like people who were with him died. At this time, the shock of being attacked by a monster returned his memories of his previous life, and at the age of one, his mental age was over 20, and his ego was established. By the time he reaches the age of 15, his mental age is (by simple math) over 35. He has a vague memory of his previous life, and although he remembers knowledge, he forgets his background and cause of death.

Despite having knowledge of modern Japan from his previous life, he seems to lack common sense such as manners, but he draws the line that he only wants a friendly attitude as a relative only in private (the person himself is that) intended). On the other hand despite his good personality, he is often scolded by Merida because he has a lack of sense of urgency for his own power and does not care about what others see In the comicalized version, the line "Did I do something again?" became famous and has been made into goods.

Because he had no interest in anything other than magic and didn't want to be taught, on the day he became an adult at the age of 15, he said, "I haven't been taught anything about common sense in this world... Fascinated by the magic that was a product of fantasy in his previous life, he learns about magic from Merlin and about magic tools from Merinda. Also, due to her training since childhood, she is good not only in magic but also in physical arts such as swordsmanship. On the other hand, since she lived in the depths of the forest until she became an adult, she was ignorant of the world.

With his background as "Magi's Grandson" and exceptional grades, he entered the school at the top of his S-class. Based on the recollection of his previous world, Shin's knowledge of science and astronomy revolutionize the world's magic tools. Over the summer break, Shin and his grandparents did intensive training with the Ultimate Magic Research Society to prepare for massive demon outbreaks while deployed in a special unit called the Ultimate Magicians, hopefully, to prevent other academy students from getting conscripted into war. Soon afterward, Shin's (Earth-modern) appliances prompted him to open his own shopping mall. His title is Demon Lord, which he does not like.

Personality


 * Shin, due to having some memories of his previous Japanese life, showed a more mature and serious nature than most children. He was naturally curious about all the things in his new world that were different from the one he remembered and sought to learn all that he could.
 * As he is unaware of how potentially groundbreaking his creations are, Shin shows a somewhat ignorant and reckless attitude, causing others to worry about what he might do next. This causes people close to him to worry about him doing something catastrophic, should anyone bring harm to his loved ones.
 * It's not that Shin doesn't have common sense, it's just that he applies the common sense of 21st century Earth to everything; because of such his values and morals are naturally out of place to those of people who were born in a world akin to the Medieval Era. Most notably would von Claudes making him and Sicily get engaged due to noble traditions right after they become a couple; Shin later made a proper proposal by Earth's standards, noting he was doing it out of order (but did so because it didn't feel right to him unless he did).
 * Shin tends to approach his new world of magic through a lens of his old world of science. He applies scientific principles to how he pictures his spells and the effects they have on the world around him. By increasing or decreasing physical aspects of chemical makeup, Shin is able to get magic to do things others aren't; even Merlin was able to just grasp this concept.
 * On top of this, Shin tends to lose himself in rage when someone close to him is put in significant danger, especially being the case for Sicily when a large number of demons were deliberately targeting her.

Abilities
In addition to continuing to receive the scientific knowledge of his previous life and the guidance of Merlin, who is called a sage, since he was only 3 years old, he applied the knowledge of his previous life to the techniques he was taught. At the age of 20, he single-handedly subjugated disaster-class monsters, and if he got serious, he had the magical ability to easily defeat a demon.

Furthermore, since he received instruction in swordsmanship from Merlin and Merida's acquaintance, "Sword Saint" Michel Collins, he has acquired more ability than an active soldier even in hand-to-hand combat. In addition to attack magic, he inherited the knowledge of human anatomy and diseases from his previous life, so he has impeccable powers such as being able to treat serious injuries and intractable diseases accurately. As a result, the second name attached is "Magic King", that is, "Demon King".

In terms of his combat power, he is undoubtedly the strongest in the series, and he was injured in battle only twice during the series. However, contrary to this, the person himself is ignorant of common sense in every sense. Based on the knowledge derived from modern Japan and his own magic theory (imparting multiple properties using kanji), he creates only items that are clearly over-spec, so the evaluation from those around him, including his relatives, is "If you leave it alone. I'll do something."

【Physical Enhancement Magic】
 * Magic that gathers magical power and strengthens one's own body. It's common magic, but like healing magic, it uses the knowledge of the human body based on the memories of the previous life to efficiently strengthen the physical ability many times.
 * Magic in this world is activated by collecting magical power and imagining it, so you can use lightning magic and other magic depending on your imagination. In addition, since he practiced mana control every day from the age of 3, he can collect an abnormal amount of mana.
 * He has been out hunting in the forest near his house since he was a child to gather food, so he can perform extremely precise attacks such as hunting monsters without hurting them at all.
 * Also, special magic is used depending on the image.


 * ─ Defensive magic Magic barrier/Physical barrier
 * A defensive magic that uses magical power to create the image of a wall. It's common defensive magic, but Shin, who can control a tremendous amount of magical power, can put up a very powerful barrier. It boasts an impregnable defense that can never be broken during the work, such as collecting and using a lot of magical power to prevent the attack of its nemesis Schtrom.
 * ─ Attack magic By utilizing the enormous amount of magical power cultivated through magical power control training that has been continued since childhood, along with the knowledge of the previous life, by adding the fundamental principle to the image process, its power and accuracy are dramatically increased. has improved too (Additionally, in the anime version, there is a depiction of his previous life where he was involved in the publication of science textbooks for children.)

 * The magic of flames is used to create a bluish-white flame (Blue Flame), imagining it as sending oxygen to the flames (combustion). In some cases, the shape is used as a spear or a bullet. It has the power to defeat disaster-class monsters and devils with a single blow and melts the ground. When used in a fit of anger, it burns down the enemy without a trace with flames that turn pale and turn white.
 * Water magic creates a large amount of water and compresses it to increase its power.
 * Ice magic creates and uses ice by controlling water molecules.
 * Wind magic is often used in the shape of a blade, and this also has the power to tear demons apart. It can also compress air and use it as a bullet.
 * Earth magic is often used as a counter, such as shooting a lump of soil as a bullet or sticking out a stake. Also, in Volume 10, he created walls one after another while flying around the country's capital, surprising the military forces of each country and watching to the point of escaping from reality.
 * Explosion magic increases its power. (Hydrogen, etc.)
 * ─ Healing Magic
 * Shin13.gifnal healing magic is activated with an image of a strong feeling of compassion, but in Shin's case, he has knowledge of his previous life, so he can use it without feeling compassion because he treats based on the structure of the human body. can. When it heals, it collects cells from different parts of the body and temporarily transforms them into pluripotent cells for repair, so it seems that using it will make the body thinner, and in severe cases, it seems that proper rehabilitation is required.
 * On the other hand, healing magic only works on living creatures, and even Shin cannot revive those who have already died.
 * ─ Gate
 * Shin8.gifal movement magic was developed by Shin. Developed based on existing different space storage magic. It is an image that directly connects two different spatial points, and it corresponds to warp rather than transition. Merlin, who understood the mechanism, also learned it, and later all the Ultimate Magicians learned it from Shin. Because it is based on an image, the destination is limited to places the caster has been to in the past. Passing through the gate itself is possible even for those who are unrelated to the place.
 * ─ Optical Camouflage
 * Interferes with magic around yourself and distorts the light to make yourself invisible to the opponent's eyes.
 * ─ Floating magic
 * Shin12.gifoped to counter Schtrom's ability to magically float in the air. It is possible to float in the air by applying an image of anti-gravity to objects, people, and yourself. Since it is an image of anti-gravity, it can only control altitudes up and down, and it is possible to fly forward, backward, left, and right by using wind magic. In the work, only Shin and Schtrom can be used, and when Shin floats others, he casts floating magically on himself and controls it with his own wind magic, making it possible to move in the air.
 * ─ Marker
 * Set a marker where you want to aim and use it imagining that the magic will be guided there. In the work, it is used in conjunction with a water bullet against a group of monsters, and it is hit by a mistake with the guidance that puts missiles to shame. It seems that the magic was originally developed to bring down prey with strong vigilance when hunting.
 * ─ Directional Explosion Magic
 * Shin11.gifoped to prevent yourself from getting caught up in explosion magic when used at close range. Since the direction of the explosion is adjusted, not only the explosion but also the shock wave will not come out of range. Also, since the range is narrowed down, the power is higher than normal explosion magic.
 * Shin puts a mixture of oxygen and hydrogen around the blue flames but makes sure they won’t touch each other which when thrown toward a place a lot further away, causes a tremendous explosion and leaves a huge crater.
 * ─ Thermonuclear Magic Used in the final battle against Schtrom. Using the forbidden weapon from his previous life as magic, he annihilated Schtrom. In addition, in order not to cause damage to the surroundings, the energy is escaping into space by giving it directionality similar to directional explosion magic.

Combining the power of magic with the knowledge of her previous life, she creates many advanced things. However, as mentioned above, it's clearly over-engineered in this world, so it's standard for people around them to criticize him, saying, "What are you making?" In addition, magic tools are a headache not only for Merida and Org, but also for Thor, whose family runs a craftsman town, and he is always on the lookout, and in a sense, he is a source of trouble for those around him more than magic.
 * In other words, it is an overkill magic that concentrates the power of a nuclear explosion on just one person. Not to mention the people around him who saw the magic, Shin himself has decided not to use it again.
 * It is also a double-edged sword that can wipe out the surroundings including yourself if you make a mistake in control.
 * By the way, I used it 3 times in my work.
 * (The first time was a test shot before the decisive battle, and the clouds in the sky were blown away, and the second and third times were used in the battle against Schtrom. The second time, Miria became a shield for Schtrom, so it ended in a misfire, but 3 The second time is stabbing Schtrom.)
 * }

Shin himself is somewhat self-aware, and has imposed restrictions on himself, such as "do not adversely affect existing industrial forms" and "absolutely never create weapons of mass destruction." In addition, most of the things he has developed are basically things that are closely related to daily life and defense equipment, and in fact he has not developed any weapons other than the vibration sword. (A rifle for long-distance attacks was made in the early days, but since magic tools for long-distance attacks have been widely used in the work, it is treated as unacceptable. ) This is due to the fact that the idea of ​​making weapons was weak because there was nothing. Nonetheless, as I mentioned earlier, it's over-engineered during production, so if it's distributed poorly, the market value and market price will be greatly distorted, so there's no change in the fact that people around you must keep an eye on it...


 * Vibration Sword - A sword with "ultrasonic vibration" applied to the blade. It can easily cut targets regardless of the sword's material, but the blade's strength does not change, so it may break. Therefore, Tony's idea was to develop the "Exchange Sword" and solve it by exchanging the blade when it breaks.

In the final battle against the demons, with Merida's permission, they were lent to soldiers from various countries on the condition that they would be strictly managed and returned after the war. In the original, they were loaned to all soldiers of each army, but perhaps because there are too many of them, in the manga version they are only loaned to elite units selected from each country. In addition, the added characters are made invisible in order to prevent copying and duplication of the added characters. By the way, Shin and Tony are regularly paid 5% each of the profit as exchange sword idea fee, and the monthly income alone reaches the general annual income. (By the way, when Tony found out about the forehead, he was so surprised that he fell down with a pale face.)

TV Anime
