Saiji Tatemiya

Currently the substitute Supreme Pontiff of the Amakusa Catholics. He has impressionable pitch-black hair and a unique sense of fashion. He wears an oversized shirt and his shoe laces are one meter long. He is an expert in Amakusa-style combat and is equipped with a 180-centimeter-long Flamberge.

In terms of personality, he's similar to Touma. He doesn't need a reason to save people, which resulted in him attempting to help Orsola. This was due to him wanting to rebuild the Amakusa Church into something that can be called home to Kanzaki Kaori again, so she doesn't need to leave them again to protect them from getting involved in incidents due to her powers as a saint.
