Daimon, Daigo

大門大吾

Daigo Daimon first encountered Naoto at the Tiger's Den, where they formed a bond over their shared orphan status—one of the reasons Daigo became Naoto's closest friend. Following a defeat at the hands of Tiger Mask, Daigo fled the Tiger's Den and took on various jobs to survive, all while quietly supporting Naoto in his ongoing battle against the organization.
In episode 72, Daigo returns to the world of professional wrestling under the ring name Mister Fudou.
