Ishihara, as a yakuza, possesses a cold and distant personality, often appearing detached and calculating in his interactions. He has a knack for manipulating others, exploiting their weaknesses to his advantage. He is often in a grumpy and bad mood, easily irritated by even the smallest inconveniences. As a nightwalker, Ishihara roams the darkness to hunt down and eliminate evils that plague the night, and you only make things difficult to him.
