Kongou

Kongou is the no-nonsense teacher of the Lustrous, packing a serious punch when it comes to fending off Lunarians. With a treasure trove of knowledge, he usually keeps to himself, speaking in a straightforward manner that’s all business. He’s more stoic than a rock, and his emotions are a bit of a mystery—rumor has it he’s got a poker face that’s hard to read. When he does crack a joke, it’s still in that deadpan style that makes you second-guess if he’s serious. Deep down, he cares a lot for the Gems and feels personally responsible when they get hurt. Fun fact: he’s a prayer machine created by Dr. Ayumu, whom he considers like a mom!
