The Forgotten Girl

Reginald "Shark" Kastle is being haunted by his past. Everything he thought knew doesn't add up anymore, and it's eating him alive. But when he meets a girl who sparks old feelings and even older memories, he starts to wonder. Could he have forgotten more than just his ancient past? (I'm using the English names, so sorry, but that's what I'm used to.) I DO NOT OWN YU-GI-OH! ZEXAL!
