Seigi

Akatsuka Justice, better known by his nickname "Seigi", is the main protagonist of the manga and anime Taboo-Tattoo. Originally a normal high schooler, after saving Professor Wiseman from a group of thugs, Seigi was given one of the most powerful known tattoos, "Void Maker".

Personality
Seigi's a surprisingly complex person, often switching from being a kind person to being an violent one, but ultimately he's a good kid at heart, so you can bet he'll aways fight for what's right.

Abilities

 * Void Maker: A tattoo which grants Seigi the power to create miniature black holes (or "voids") that instantly swallow up anything in their path. Being a "trigger-less tattoo", Void Maker does not require any prerequisites in order to be activated, although it's noted to crave blood. Do to having a mind of its own, there are moments when Seigi is unable to control Void Maker. Supposedly, Void Maker is the only tattoo that can reveal the truth about tattoos, but it is unknown whether this is true or not.
 * Martial Arts: Seigi is a highly capable martial artist. Since a few years ago he was trained by his grandfather and no one has beaten him other than him and Izzy.

Trivia

 * Akatsuka's nickname, Seigi, literally means "Justice".
