Fukurou

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 laidback personality and his motto seems to be Dont worry about it. Being Karasus best friend Fukurou failed the mission to kill him when he was declared a traitor deciding to aid Karasu. He seems to find our timespace less painful than Karasu looking fondly on Ai Y and his younger self and admonishing Y and Isami to stay friends. Like Karasu he looks very different from his younger self tall muscular with a long brown ponytail and only one eye presumably lost in a gang war in his teens. Fukur is Japanese for owl.
