Fukurou
フクロウ
He is Isami in the same future timespace as Karasu. He also became a Dragon Knight. Unlike the tormented Karasu, Fukurou managed to keep his sense of humor and laid-back personality, and his motto seems to be “Don’t worry about it.” Being Karasu’s best friend, Fukurou failed the mission to kill him when he was declared a traitor deciding to aid Karasu.
However, Noein killed/absorbed Fukurou after Haruka changed the future she saw in which it was Karasu who killed him. Fukurou is a close friend with the future Ai, and expresses his wish to see her one more time as he dies. Fukurou’s spin weapon appears to be simple energy blasts.
