Eizo Tanuma is a veteran detective on the Police Force and the man who once partnered Naomasa Tsukauchi. Relaxed where his former partner is rigid, he quietly holds some of the era's biggest secrets, including Knuckleduster's past and the cover-up of All Might's first fight with All For One.
Age shows on Eizo mostly at the hairline, which has crept back far enough to leave him going bald, and in the thin beard along his jaw. What hair remains is dark and cut short. He dresses the part of a career detective: a dark suit over a black waistcoat, finished with an unpatterned tie.
Set beside Naomasa Tsukauchi, Eizo comes across as the easygoing one, calm and sociable in a way his partner never manages. That surface hides nothing about his competence, since he treats the work seriously and his hunches land close to the mark more often than not. He also knows a great deal more than he lets on, being among the very few aware that Knuckleduster once operated as the Hero O'Clock.
Eizo carries a detective's badge on the Police Force, where Naomasa Tsukauchi was once his partner. Given whatever facts are on the table, he can reason his way toward the motives and intentions driving any villain or criminal outfit, and he lands close to the truth. He is on record with a blunt view of the Naruhata Vigilantes, arguing they are better aimed at actual villains than left to cause trouble, since the authorities plainly cannot cover everything themselves.
Free Walker is his Quirk, and its capabilities have never been spelled out; the name alone suggests it keeps his legs moving freely without tiring. His reach into buried history is considerable. He was one of the handful aware that All For One and All Might had fought their original battle, and he helped bury the whole affair. Word is that the injury All Might carried and the name behind the mask were known to him too, since he served as the hero's first contact inside the police until Naomasa took the role over. Away from the job, he is fond of cigarettes and alcohol.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
