Five years ago on a snowy night, Genji came upon a helpless leopard cub and brought him home. Since then, Koshiro has stayed by Genji’s side, growing up into a healthy leopard—who also can shift into a handsome young man. Neither understands what Koshiro is or where he came from, but Genji has taken care of him regardless. Now that Koshiro is growing older, his body is going through changes he can’t quite figure out. All he knows is that he wants to be closer with Genji in a more physical sense. Can Genji help him with these unfamiliar urges, or is this a step too far for the former yakuza?
