It's no good to overestimate me. Victory is something that you grasp by always being modest, you know.


Rudeus Greyrat (ルーデウス・グレイラット Rūdeusu Gureiratto) is the main protagonist of Mushoku Tensei. He was an overweight 34-year-old Japanese NEET who is reincarnated into another world after being hit by a truck whilst saving some kids. Realizing he wasted away his previous life, he resolves to live this new one to its fullest and the series revolves around how he impacts his new world all whilst slowly growing out of his reclusive ways.


Rudeus is a tall, well-built, and cool-looking man. He was born with brown hair, but after his second encounter with Orsted, his hair temporarily became white. His eyes are also slightly mismatched as he switched one of his eyes out for a demon eye. Like Paul, he also has a mole underneath his left eye.


Because of his former life, he is careful not to get carried away and become arrogant. As a result, he is extremely self-aware and humble because he does not want to revert to his old self.[7][8] He is a kind person, helping his friends and protecting his family whenever needed. Due to being capable in many fields, people have high expectations of him. Rudeus is very polite to others, often making them uncomfortable.

One side effect of being formerly Japanese is that he doesn't want to kill anyone. However, he displays aggression and blood lust to anyone threatening his family. He is extremely perverted and even though he has this shortcoming,[9][10] his family and friends still love him since he always takes care of them to a great extent. Even with very high magic capacity and high potential in battle, he often lacks the confidence to fight his enemy.


Rudeus was a 34-year-old NEET otaku in his previous life. It is stated by Rudeus that he was born in to a well-off family, and was the fourth child out of five children in the family. When he was in elementary school, he was actually quite a bright student, and was praised for being smart for his age. In junior high, he joined the computer club and and saved up his allowance to build his very own PC. However, he got so focused on building his PC, he neglected his studies. During his high-school years, he was a victim of severe bullying that resulted in him dropping out. For example: when he was in line to buy lunch, some person cut in front of him and he gave them a piece of his mind. However, the person who cut in front of him was an upperclassmen, and beat him up, and hung him up naked, taking pictures of him, giving him the nickname, "Pencil Dick". His family tried to encourage him to go back to school, but he brushed them off. There was at least one classmate whom he had a good relationship with who came by everyday to deliver homework. However, he pushed him away too when he also tried to get him to return to school.

He continued being a shut-in, living off his family, for twenty years. However, this toxic lifestyle finally came to an end when his parents passed away and he refused to even attend their funeral. This ended up being the last straw for his remaining relatives, prompting them to disown him.

Homeless and penniless, he wandered the streets aimlessly while reflecting on his life until he came across three high-schoolers on a road. Seeing a truck coming toward them at high speed, he mustering all of his strength and manages to push one of them away. However, this caused him to get run over himself instead, killing him. The next time he opened his eyes, he was reincarnated as his current self. Realizing he had been given a second chance, he declared he would live this new life to its fullest.

Rudeus was born with the "Laplace Factor". This means that his development as a fetus was influenced for him to become a potential vessel for the Demon God Laplace to be reincarnated in, resulting in his abnormally large mana capacity. This is also why it was this body that he was reincarnated in, as it did not have a soul of its own and would have otherwise been stillborn.


  • Rudeus: "Hey, Eris."
  • Eris: "What?"
  • Rudeus: "Can I grope your tits?"

  • Rudeus: "Aisha... Norn... I'll help you anytime you need... If you are in trouble,, don't hesitate to rely on me... You might think I'm unreliable, but no matter what, I'll do everything in my power..."

  • Rudeus: "I think Pax is a jackass. But he should be able to change; I've changed. There isn't anyone who cannot change."

  • Rudeus: "Some people just prefer to see a more dramatic world. Fact is stranger than fiction. Reality is strange, helpless and disappointing."

  • Rudeus to Claire: "And what if she gets pregnant? Will you bear it? Will you consider bearing it? Even if she does give birth, what about Zenith's intention? What about my feelings? What do you think will become of the children that are left behind? What do you know about a person's mother! What do you know about your own daughter! Substantially, what's up with this function! Means of treatment? A machine to give birth? Don't joke around!"

  • Sylphy: "This time, Rudy won't be here for the birth?"
  • Rudeus: "No, I'll be here, in the house."
  • Sylphy: "But... Rudy..."
  • Rudeus: "I'll be here."

  • Rudeus: "I will protect Sieg even if the Sky Fortress falls."

  • Rudeus: 'Eris, I want to go to bed with all four of us like this, is that fine?"


These are the current achievements that Rudeus gained through his adventure, action, and training:


  • Rudeus' name before reincarnation remains unknown.
  • Rudeus can speak multiple languages (Magic God Language, Beast God Language, Fighting God, Human Language) by the time he was 9. Which he learned when he tutored Eris.

  • All of Rudeus' wives seem to get pregnant right before he goes on a journey to somewhere.
  • He has a tendency to always overestimate his opponent.
  • Incidentally, although he is Emperor Ranked in Water Magic, he has mostly used Earth Magic in combat.
  • He was given the title "Hero" due to him being able to defeat Demon Kings (initially Badigadi but, he refused to call himself a hero, and later on after defeating Atofe, he accepted the title).
  • It can be noted that even though Rudeus is unable to wear Touki, he has attained a Saint-class combat ability of a swordsman with his 『Magic Armor Mk II B 』 and God-class power with 『Magic Armor Mk I 』(The latter one was stated by Atofe).
  • He is feared by all Demon Kings after they learned he is a "Hero" who defeated Atofe.
