Tenjō Amanohokosaka

Lord Tenjo was Bang Shishigami's former sensei and leader of Ikaruga before he was slain by Jin Kisaragi during the Ikaruga Civil War. This caused Bang to seek revenge on him. In one of Bang's endings in Story Mode, Valkenhayn Hellsing mentions that Lord Tenjo's son might still be alive. Bang heads to Ikaruga in his canon ending to find the answers he seeks.
