Bankotsubo is extremely arrogant, almost grievously so. He looks down on humans, as well as his own kind with contempt and thinks them fragile and trivial. Bankotsubo is also fond of chaos and destruction, and is manipulative to a fault. He tricked his fellow tengu into allowing him close enough to murder their leader, as well as having a hold of sorts in connection with Ein's missing memories. Ironically, because of his superiority complex, Bankotsubo's defeat was quick and unceremonious.
