Mushoku Tensei: Magic Swordsman
On the eve of being drafted as a pro soccer player, Noel Miller was hit by a drunk driver and became paralyzed from the waist down. Falling into a deep depression and believing himself to be a financial burden to his family, Noel goes to kill himself. However, he died after pushing away a boy from a speeding truck and thus reincarnated as Rudeus Greyrat.
Now with a body that could walk and run as well as the prospect of learning magic and swordsmanship, Rudeus Greyrat is resolved to become the greatest Magic Swordsman in the world.
Author's notes: Loved Mushoku Tensei, hated the main character. Wanted to write a story with the great world building of MT but with a better main character, that while also possessing his own set of flaws, is at least not a perverted horndog who lusts over the body of children.
MC is more mature and charismatic than original MC, but still has his moments of childishness. He is also more focused on swordsmanship and martial arts than magic.
People who keep asking if it's a harem: I don't know yet. Confirmed pairing Eris. Anyone else, I am undecided.
