Justice "Seigi" Akatsuka (赤塚 正義 (セーギ), Akatsuka Jasutisu (Sēgi))

Seigi has a strong sense of justice and ends up receiving a mysterious tattoo after rescuing a homeless man from some thugs. Seigi has trained in the Akatsuka-style of jujitsu since childhood under the supervision of his enthusiastic grandfather. His Power Crest, "Void Maker", allows him to create black holes and regenerate from injuries; it's also one of the few tattoos which does not require a trigger like the others. Due to his parents having "weird ideas" when he was born, his given name is written in kanji but pronounced as the English word. Seigi preferentially goes by his nickname, the traditional Japanese pronunciation of his given name.
