Hapsiel

A pansexual Class-3 angel that was sealed within the Academy grounds 20 years ago by Professor Eitarou and Professor Stein, who is later accidentally released by Metalys and wrecks havoc upon the school by hugging everyone he comes across in a grip they can't escape, then giving them a massive kiss. He finds every attempt to hurt him, such as swords hitting his energy barrier, to be pleasurable.
