19-year-old Mugen is the straightfoward smartass. He not only has an attitude but a large appetite. Orphaned at a young age, he raised himself in rough neighborhoods. Mugen developed his own fighting style called "champuru kendo" combining martial arts and anything he gathers up from past fights.
Mugen is a happy-go-lucky young man who enjoys eating, sleeping, women, and swordfighting. Mugen has no qualms over beating you up to take your money to feed himself.
Mugen choice of clothing is between hip hop and samurai, wears wooden getas, and sports blue band prison tattoos on his wrist and ankles.
