A bear Transient and high school student who is highly intelligent and knowledgeable in many subjects. He skipped a few grades to enter a university medical research lab. His personality, however, tends toward cowardice and nerves. The people around him take advantage of those attributes and force their troubles onto him. He currently lives in an apartment complex that once allowed pets and has now become a dorm for Ueno-based Therian Transients in Taito Ward.
