Light Novel Mushoku Tensei -Isekai Ittara Honki Dasu-/Mushoku Tensei

[perspherspley]

A 34-year-old NEET otaku was chased out from his house by his family. This virgin, plump, unattractive, and penniless nice guy found that his life was heading towards a dead end. He recalled that his life could actually become much better if he can get over the dark history of his life.
Just when he was at the point of regret, he saw a truck moving at a high speed with 3 high school students in its path. Mustering all his strength, he saves them but ended up getting run over by the truck which kills him.
The next time he opened his eyes, he was reincarnated to a world of sword and magic as Rudeus Greyrat. Born to a new world with a new life, Rudeus declared, "This time, I'll really live my life to the fullest with no regret!" Thus begins the journey of a newly made man. (Original from animesuki.com)

That's one of the craziest thing I have ever read.

Just finished reading this LN and it's pretty good, and the ecchi stuff leads to good things for the protagonist so it's not just a "teaser" filled LN.
