Despite being bullied, scorned, and oppressed all of his life, a 34-year-old shut-in still found the resolve to attempt something heroic—only for it to end in a tragic accident. But in a twist of fate, he awakens in another world as Rudeus Greyrat, starting life again as a baby born to two loving parents.

Preserving his memories and knowledge from his previous life, Rudeus quickly adapts to his new environment. With the mind of a grown adult, he starts to display magical talent that exceeds all expectations, honing his skill with the help of a mage named Roxy Migurdia. Rudeus learns swordplay from his father, Paul, and meets Sylphiette, a girl his age who quickly becomes his closest friend.

Abilities
Rudeus doesn't have cheat abilities that accompany reincarnation (for some reason, he has a high limit value for total magical power "Laplace Factor"), and most of the abilities he obtains are the result of his own tireless efforts. Rudeus is a powerful magician born with a strong Laplace factor which is one of the reasons for his great magical power besides his intense training at an early age. As he was reincarnated from another world, he is immune to Orsted's curse. This is a trait that is inherited by his descendants.

When he was a child, he learned the language of the Central Continent, "Human Language", while my father Paul read to me, learned the language of the Great Forest, "Beast God Language" from Ghyslaine, and learned the language of the Magic Continent from the dictionary I received from Roxy. He learned "Magic God Language" and self-studyed "Battle God Language", the language of the Begaritto Continent whose grammar is close to human language.

However, there are some languages ​​that cannot be used, such as ' Tenshingo ', ' Umishingo ', and 'Ryujingo', which are minority languages ​​and have no materials or opportunities to learn. In addition, it is possible to read, write and speak the characters and languages ​​​​of the previous life (real world Japan) as they are.

Rudeus trains his body by running and modern Japanese muscle training (push-ups, sit-ups, squats) every day, so his basic physical strength is high. However, since he was unable to learn physical strengthening through fighting spirit (a technique that uses the magical power within the body to explosively improve physical abilities), compared to warriors with fighting spirit, his power and reflexes are considerably inferior, making him a high-ranking magus. Since childhood, as part of his training in magic, he has been making dolls (figures) that apply chantless earth magic. There was a time when he was obsessed with figurines and plastic models in his previous life, so his dolls are quite good, and Zanoba, who is a doll otaku, calls them "supreme".
 * 【Voiceless Incantation】
 * Rudeus is one of the few people capable of using a voiceless incantation, and even rarer as a person who can use voiceless incantation with melded magics.  He cannot use voiceless incantation for healing magic due to his lack of understanding in regards to how mana is manipulated to heal. A normal Magician takes at least five seconds for a simple spell, while for higher-level spells its thirty to sixty seconds. Rudeus can do it almost instantly no matter what difficulty of the spell, with the exception of healing magic. Rudeus needs to use the chant of a new spell being taught to him before he can use its voiceless incantation version which puzzles Orsted.
 * 【Demon Eyes】
 * When he was born, both eyes were normal eyes, but when he was 11 years old, he met Kishirika, the Great Emperor of the Demon World, who changed his right eye to a demonic eye. She later had her left eye changed to another demon eye.
 * 『Foresight』
 * It's a Demon Eye that Kishirika gave to Rudeus for giving her food replacing his right eye. It allows the user to see a certain amount into the future. It is difficult to adjust the focus point; the farther into the future he looks, the more unreliable it becomes. The power of Demon Eyes are adjusted according to the amount of mana poured into them. The more mana Rudeus inputs into the Foresight Demon Eye, the farther into the future he can see. Rudeus is able to fine-tune the eye to see 10 seconds into the future reliably.
 * Experienced warriors can negate the Demon Eye's usefulness in battle by making split-second decisions, forcing the eye to see multiple futures. This is learned when Rudeus duels Ruijerd. Some beings such as Badigadi are completely immune to the eye when wearing the Fighting God Armor. The eye can also act as a conduit for another being's power as Hitogami was able to show Rudeus a vision of where to find Aisha and Lilia through his eye. Another weakness of the eye is that it does not pick up sounds and as such, Gyes was able to incapacitate Rudeus using Howling magic.
 * Overuse or losing control of the eye may cause the user some sort of pain and nausea as a result of overloading the brain. This is shown when Rudeus felt a moment of extreme nausea after Hitogami used the eye to show him a vision of the future, or when he originally received the eye and it took him a while to learn to control it since it would give him a double vision.
 * 『Clairvoyant』
 * It's a second Demon Eye that Kishirika gave to Rudeus for giving her a donut when she is captured by Atofe replacing his left eye. It allows the user to see far away. However, the "focus point" is difficult to control. Rather than acting as a scope, the Clairvoyant Eyes seem to change the perspective of one's vision, with the amount of mana determining the distance from the user.
 * 【Magic / Witch Craft】
 * When it comes to magic, he has a natural talent, and he improved his talent with Roxy as his teacher when he was a child. His natural growth allowance is extraordinary due to a peculiar constitution called the Laplace factor (the total amount of magical power in a lifetime is determined by how much this growth allowance can be drawn out by training by the end of childhood). In addition to that, since his consciousness was connected to him from his previous life, he began training very early on, and boasted a huge amount of magical power that was far from human. He also masters Chantless attack magic. Mushoku Tensei3.gif
 * Even an excellent magician will not run out of magical power even if he fires a series of saint-class or king-class magic that runs out of magical power after a few hits. It is said that its amount of magical power is comparable to that of the demonic hero "Majin" Laplace. The advantage of Chantless magic is that you can change the power and effects of attack magic, and by using a huge amount of magical power, even low-rank magic can be as powerful as an emperor class. He also reproduces a technique called "Multiple Casting", which uses two types of magic at the same time, with Chantless magic, and is able to quickly activate "Mixed Magic", which normally takes a long time.
 * In addition to Chantless magic, it is easy to imagine "mixed magic", which is a fusion of phenomena from the knowledge of natural phenomena in the previous life, so it can be efficiently reproduced (King and Emperor class magic is within Saint class + Since it is a derivative of mixed magic, it became synonymous with mastering all offensive magic except God class, which requires a separate magic circle, when the Saint class of four attributes was acquired).
 * In addition, he has a high sense of magic, such as self-studying magic that he has only seen once, and mastering the control of the demon eye in a short time. However, he cannot fully use that magical power with a human body, and is no match for the strongest class magicians such as the demon god Laplace. Also, only attack magic can be used without chants, and healing and detoxification magic cannot be used without chant (because there is no medical knowledge and it is not possible to imagine healing the human body).
 * His rankings as a magician are as follows:
 * «Water Emperor Ranked»
 * «Earth Saint Ranked»
 * «Wind Saint Ranked»
 * «Fire Saint Ranked»
 * «Healing Magic - Saint Ranked»
 * «Detoxification Magic - Saint Ranked»
 * «Barrier Magic - Intermediate Ranked»
 * 『Nuclear Explosion』: Unofficial God-class magic(stated by Orsted) that Rudeus created in a desperate attempt during his fight against Orsted. By focusing a tremendous amount of magic power at a designated area, he creates a huge explosion around his pinpointed target and leaves behind a mushroom-like cloud similar to a nuclear explosion. During the second confrontation with Orsted, he managed to destroy a village with this magic. Even with Orsted opening the First Dragon Gate to tremendously lower its power, the explosion was still packed with power similar to Laplace. It is hinted that this is Fire-type magic.
 * 『Ran Ma』- Disturb Magic: It is a unique magic that Rudeus learns after observing Orsted in their first fight and works by interfering with the magic of the opponent disturbing it thus preventing it from working. This is a very rare and difficult technique as Sylphiette, who is a talented mage in her own right, had a lot of trouble learning it.
 * 『Dry Steaming』: Dry Steaming is a melded magic of fire and wind originally developed by Rudeus to dry wet clothes with a risk of damaging the fabric. Used to block the opponent's field of vision. It is often used in conjunction with quagmire.
 * 『Explosive Stone Cannon』: It is a variation of Stone Cannon originally developed by Rudeus. The stone is hollow thereby exploding at the point of contact.
 * 『Electric』: Realizing that 『Lightning』 might be a bit overkill as a single target spell, Rudeus weakened the King-class Water magic. Rudeus was able to use Voiceless incantation to create a miniature thundercloud, compressing it, and designating a target for 『Lightning』. In order to distinguish it from the normal overpowered spell, he named it 『Electric』. The Electric strike is hard to avoid and can numb the nervous system, making it a very useful spell against people who can wear Touki. It is effective against the Immortal Demon Race as demonstrated in the battle against Atofe.
 * 『Light Spirits』: Rudeus can make a light spirit scroll and use them to summon bright light spirits as a source of light.
 * 『Howling Magic』: Howling is a type of magic that can locate or paralyze enemies by using sound as a medium, but Rudeus can only use it to surprise or scare opponents. He learned it from Gustav Dedorudia.
 * 【Fighting Style】
 * 『Sword Techniques』
 * Intermediate-ranked Sword God Style
 * Elementary-ranked North God Style
 * Elementary-ranked Water God Style
 * Since Rudeus cannot make use of Touki, he cannot rise to Advanced ranked Sword Techniques.
 * 『Saint Dragon Battle Aura』
 * Saint Dragon Battle Aura is a fighting style that was created by Dragon God Urupen, who was considered to be the weakest Dragon God due to having the lowest magical capacity ever and rose to become the strongest with this fighting style. It involves defeating an opponent using the minimal amount of magical power. It is described as a fighting style by Rudeus that combines magic arts and the real world martial art Wushu.
 * Rudeus is currently being taught how to use this fighting form by Orsted. This fighting technique is the best fighting style for Rudeus due to it's great compatibility with the 『Magic Armor』, making the 『Magic Armor』 performance more potent, efficient, and useful during combat. It should be noted that it is a fighting style and not a type of touki as Rudeus lacks the ability to use actual touki.
 * 『Tactics』
 * He has been noted by others to be a battle genius. During his first fight with Paul, he was smart enough to trap Paul's leg to restrict his movements. During his time as an adventurer, he was known for his skill with Quagmire and trapping opponents with earth magic before attacking. After training with Orsted, he became more aware of his tactics and was able to perform the strategies more efficiently since he was conscious of them.
 * In the case that he is trapped by a high level barrier magic that restricts his magic, he will use the Manatite stone to destroy the seal and use a combination of Quagmire, Mist, and Electric to slow down or disable his opponents before using a summoning scroll to summon his trump card, the Magic armor MK I, to defeat his enemies should the need arise for the fire power. Taking stories and legends from his previous world, he was also able to come up with a strategy to defeat a hydra that could regenerate its heads.

Production
Rifujin na Magonote commented that he created Rudeus aware of his controversial personality. He intended Rudeus' actions would be more meaningful in the process. He had no issue criticizing Rudeus at an early stage and left it to the audience to judge him. Magnote wanted the audience to pay attention to a specific side of his character and be able to relate to him. Earlier, he said that I felt a big response in episodes 6 to 7 of the web version of the novels, but that was just when Roxy took Rudeus out. Thanks to her, Rudeus overcomes the trauma. Such a story gave a warm impression to his readers and made him think, "Let's grow in this direction."

After publishing the first parts of his work, Rifujin wrote that he intended the series to last at least a hundred chapters. Due to criticism towards his work, Rifujin considered ending the series prematurely but was inspired to continue when his work reached the first place on Syosetu's daily rankings. Originally, the story arc where Rudeus' reunites with Aisha was supposed to be completely different from the published work. The author intended to have Lilia die off-screen, and Aisha to be hiding under a different identity. However, he found Lilia's death anticlimactic and decided against it; thus, he had to rewrite the story arc to make sense of her survival and lack of contact. Rifujin stated the story arc might be bizarre due to the changes but expresses no regrets in his decision; he noted Lilia's survival made him reconsider Zenith's condition in the story.

Aisha Greyrat's after-story

LexBurner's controversy
On February 8, 2021, before the premiere of the fifth episode of the anime adaptation, a Chinese streaming network, Bilibili, temporarily halted the streaming of the anime on the grounds of a "technical failure." According to fan speculation, it might have been linked to the actions of the popular Chinese influencer LexBurner, who insulted the series and its fans, with one of his remarks saying that it is "for bottom-feeders in the social hierarchy." Incited by his words, his followers went to the media-reviewing website, Douban, to review-bomb the series with a 1-star rating; although the series concurrently enjoyed a 9.2/10 rating on Bilibili. This has led to LexBurner, who was one of Bilibili's top streamers, being banned from the site. Later, author Rifujin na Magonote commented on LexBurner's actions as follows: "His words are only his personal opinion, and he is free to hold whatever views he likes. Although I am displeased at how he has insulted other viewers, anime is not made only for successful people, so I hope that those who can enjoy it will enjoy it." He further commented: "If that is the kind of online presence he is, that's just the way it is sometimes. Even in Japan, there are plenty of people like him, although they might not have his influence. As far as I am concerned, instead of engaging with him, I think it is more important to ignore him and grow your own communities. Thank you!".

The main character of the series Rudeus, has been criticized for being overtly perverted. Anime News Network found Rudeus hard to sympathize, as in early chapters he barely develops connections. However, the way Rudeus interacts with Roxy during his training as a mage was noted to benefit him, was the subject of praise. Real Sound was concerned about how the narrative portrays Rudeus' previous life as it appears to focus highly on retired school students and issues they had at school comparing it to the famous light novel series Re:Zero − Starting Life in Another World. Nevertheless, Rudeus commitment to surpassing his flaws in his new life was noted to turn him into a more sympathetic main character. Re:Zero − Starting Life in Another World novelist Tappei Nagatsuki said that one of the strongest points of Mushoku Tensei was the handling of Rudeus who is noted to suffer in a similar fashion to the main character from the visual novel Clannad. Mindo Manihar Pasaribu from Institutional Repository of the University of North Sumatra notes Rudeus, who was previously a cowardly, weak, insecure character into a hard-working, strong, or fearless character who is more confident and compassionate; This makes the novels of Mushoku Tensei served as a major appeal to the audience. Writer Niji Kusano from Real Sound said that the key to Mushoku Tensei 's success was how deep is the success Rudeus achieved in his new life despite how common it is in Isekai stories. Another element that helps the novel outstand is the mix of realism Rudeus is often seen while being mixed with the popular high-fantasy style.

Anime
The anime adaptation received positive responses from both critics and audiences, having considered one of the best anime of 2021.

At the Anime Trending Awards, the series receives 18 nominations in total, with seven wins. It receives three nominations, including Best Fantasy category twice in two consecutive years, at the Crunchyroll Anime Awards. Wiriting for the first season, Irfan Ghani Muhammad from Universitas Kiai Haji Achmad Siddiq Jember noticed Mushoku Tensei often tests Rudeus' morality from different point of views. His fears of the outside world change when Roxy starts training him and takes him through a ride across the town which changes the protagonist's point of view of how society works. The scholar mentions Roxy's character faces a similar arc due to her differences from her people. HITC found the anime properly followed the novel's narrative, most importantly Rudeus' coming-of-age story, which appealed to the audience. Comic Book Resources saw the focus on Rudeus' emotions as what marks the series a major departure from other isekai storylines.

The early episodes of the second season earned controversial responses due to the more miserable portrayal of Rudeus while highlighting a decrease in the animation values. Positive response focused on how more depth was given to Rudeus as he was now alone and tried interacting with new characters.
