Is he a beast or a man? More of some or less of the other? No one knows, not even he knows. What is known is that his loyalty to Shiho Hiroto is unquestionable. Eldest Brother would walk through the fires of the 10,000 Hells for him. His word is his bond, and his bond is everything. Being left behind after a Savage Wave raid, Eldest Brother now strides two wholly incompatible worlds, doing the best that he can with what he has. Hiroto saved him from the very worst of humankind’s behaviour, and they have been together ever since.
