Akisu Kyōya (Night Lord Prowler, 卿夜空き巣, Akisu Kyōya) is an illustrious demon hailing from the invisible world of Limbo. As a Herald of Calamity, he serves Kali and dishes out havoc as a daily passtime. A wielder of the rare Gurengan, his demonic powers have been used by Kali to lay waste to entire systems. His power precedes him and his group, their reputation brings chills to the strongest of foes. After learning of the coming of Akisu and the other Heralds, Gisō was filled with fear, indicating even Kaguya was fearful of what was to come of the Heralds. Akisu has been apart of the group for a long span of time, and he is personally reputed as the Crimson Terror for his demonic ability and Gurengan prowess.
