Tenjō Amanohokosaka

Tenjō Amanohokosaka 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 R. Hellsing mentions that Tenjō's child might still be alive. Bang heads to Ikaruga in his canon ending to find the answers he seeks.

He was also the former wielder of the Nox Nyctores, Phoenix: Rettenjō, and passed it on to Bang before dying. In BlazBlue: Chronophantasma, Relius Clover revealed that Tenjō was also aware of the Rettenjō's true power as an Anti-Nox weapon and could have used its true power to bring victory for Ikaruga over NOL. However, he also realized the greater calamity that would come if he used the Nox, so he instead did not use it and passed it on Bang, resulting his death at the hand of Jin Kisaragi and the defeat of the Ikaruga Federation forces in the war.

Tenjō was the previous Imperator of the Novus Orbis Librarium and his full name was Tenjō Amanohokosaka, making him a descendant of Mei Amanohokosaka.

Tenjō's soul is sealed inside the Phoenix: Rettenjō; he sealed his soul inside of it before Jin killed him, so the latter only killed an empty shell. He did this to create an alternate method for activating Kushinada's Lynchpin.

Kagura Mutsuki, another one of Tenjō's disciples, had the responsibility of protecting Tenjō's son, Homura Amanohokosaka, who is the true heir to the title of Imperator.

Appearance
Tenjō appears to be a wise young man with long dark purple hair and wears it in a similar style to his ancestor, Mei Amanohokosaka. He wore a white mask with a red design symbol to conceal his face. He wears a Japanese red and white outfit reminiscent of emperor with a purple cloak.
