Tenmoku Ikko

Tenmoku Ikko is a massive warrior known as "the monster torch," recognizable by his samurai armor and a single-eyed Oni mask. He accepted the role of a Mystes specifically to ensure the survival of Nietono no Shana, a powerful blade capable of killing Crimson Denizens. After an unsuccessful attempt to test his strength against Shana, Ikko entrusted her with the sword, forming a partnership dedicated to fighting supernatural threats.
