Ninja

The ninja (忍者) is a secret group that served Tenjō Amanohokosaka. They are also called the Ikaruga Secret Forces (イカルガ忍軍), with Bang Shishigami as the leader. After the Ikaruga Civil War, many of them moved to Rōnin-gai in the 13th Hierarchical City "Kagutsuchi".

They honor duty above all else, and the bonds among them are extremely strong.
