Bumdeus Goonrat

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 stands at around average height (175cm), has a muscular body despite being a magician, and his looks weren't that poor when his family members are asked. He was born with light brown hair and green eyes. However, he later has Kishirika Kishirisu switch out both of his original eyes for demon eyes, causing them to be heterochromatic. Like his father, Paul, Rudeus also has a mole underneath his left eye and follows his ponytail hairstyle as he grows older.

He is also always seen wearing gray robes but rarely covers his head during his time as an adventurer. At a young age, he is careless about the outfit he wears due to traveling the Demon Continent. He has worn the same gray robes when he entered Ranoa Magic Academy which has many cuts and hems from his countless battles that makes him look like a delinquent. During his 20's, he begins to pay more attention to the clothes he wears that even Perugius Dola mentions that he started to wear some decent clothes.[7]

Following his second fight with Orsted and later the final battle against Hitogami's faction, Rudeus' hair temporarily lost its color from mana exhaustion. Fortunately, in both cases, the roots were unaffected, causing his hair to grow back to normal over time.

Personality Because of his experience from his former life, Rudeus 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.[8][9] After reincarnation he is more willing to be kind, helping his friends and protecting his family whenever needed, where in the past he would have scoffed. Due to being considered a genius, who is capable in many fields at a young age, people have high expectations of him. Rudeus is also very polite to others, often making them uncomfortable especially to those who knows of his father's notorious reputation.

Having the morals of his past life, he hesitates with the thought of killing someone. He also has a calm personality who never lets go of his smile no matter how much abuse or violence he went through but he displays aggression and blood lust to anyone threatening his family. As a descendant of the Notos Greyrat Family who likes pretty girls and big breasts, and also by influence from his previous secluded life, he is extremely perverted that he tends to touch his wives even in public, but he never makes a move on anyone other than his wives. Aside from being sexually interested in big-breasted ladies, his other fetish is panties but after living with the Boreas family for some time, he also finds women with animal ears sexy thanks to Philip's influence. Whenever he's having perverted thoughts, he displays it by putting on a lecherous smile such as when he's staring at Hilda's boobs or when he's being smothered by them while being hugged by the latter. He is also loyal to his friends that he always takes care of them to a great extent. As such, Rudeus is quite feared but is respected and loved by the people of Sharia and to some extent even the most famous or powerful beings of the Human World either fears or respect him.

Apart from carelessness in his outfit, Rudeus also loves cleanliness that he remodeled one of the rooms of his house in Sharia to be a huge bathroom which is only made by the upper nobles of Human Kingdoms and he also bathes almost everyday.[7]

Even with very high magic capacity and high potential in battle, he often lacks the confidence to fight his enemy and his legs trembles when confronted in battle[10] but manages to overcome this after surviving his first battle against Orsted whose killing intent is significantly intense compared to what he encountered afterwards even when fighting against a Red Dragon.[11] When facing a stronger opponent he knows he cannot defeat, he prefers to talk himself out of battles which also caused him to earn various titles related to this.[12]

Rudeus also greatly values his family and friends that it affects him greatly when he is in bad terms with them like when he had a squabble with Paul[13] and when Roxy forgotten him when they reunited at the Teleportation Labyrinth[14] that he threw up on both occasions.

Background Rudeus was a 34-year-old NEET otaku in his previous life. As the fourth child of five children in a well-off family, he was praised as a bright student in elementary school considering his age. In junior high, he joined the computer club and and saved up his allowance to assemble his very own computer. However, he was so focused on tinkering his computer that he neglected his studies, causing him to fail the entrance exam of his preferred high school. As a result, the only school that would take him was a low-quality one, filled to the brim with delinquents.

Upon entering his new high school, he soon became a victim of severe bullying following an incident: he stood up to an upclassman who cut in front of him during lunch. However, this person then proceeded to beat him up, hang him up naked, nicknamed him "Pencil Dick", and took and distributed pictures of him in his state all whilst no one, not even the teachers, came to his aid. This event caused him to drop out of school and isolate himself at home, having developed a phobia toward the outside world as a whole. 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. Now truly alone, he slipped futher into being a Hikikomori as time went on, taking an interest in some subjects on occassion only to quickly drop them once he saw that there was already someone better at it than him.

He continued being a shut-in, living off his family, for twenty years. However, this unhealthy lifestyle finally came to an end after both of his parents had passed away from old age and he refused to even attend their funeral. This ended up being the last straw for his siblings, prompting them to kick him out of the family home and disown him. Homeless and penniless, he wandered the streets aimlessly while reflecting on his life until he came across three high-schoolers arguing on a road. Seeing a truck heading toward them at high speed, he mustered all of his strength to run over and managed to push one of them away to safety. Unfortunately, this caused him to get hit instead, killing him. The next time he opened his eyes, he found himself reincarnated as the newborn Rudeus Greyrat in the Human World. Realizing he had been given a second chance, he declared he would live this new life to its fullest.
