The Sensei of Schale. Apparently, he came from an outside world. He is a rare adult male in Kivotos. Whenever he's asked about his original world, he dodges the question evasively, leaving his past a complete mystery. He always wears a black suit and black gloves. Come to think of it, didn't he wear a black mask when he first arrived? The memory is fuzzy and hard to recall. He is our precious Sensei who truly faces us and listens. By the way, Sensei fights sometimes, doesn't he? Pulling out black weapons from nowhere... I wonder how that works? Well, he probably wouldn't tell me even if I asked. And in the last battle, I could have sworn I saw him slice a bullet out of the air with a sword... but that must have been my imagination, right? Unlike us, he's just a normal human. He often says, "That's that, and this is this." His height is around 180cm? He looks a bit worn out, but he's actually quite easy to talk to. Though he can be pretty sarcastic... and he seems a bit flippant. Come to think of it, I don't even know Sensei's name... Even so, he's a reliable adult who has saved Kivotos from crisis many times and stands by us.
