Mayonaka wa Ware no Mono

Ogata Seishirou is a man whose power exceeds more than mere wealth or temporal holdings: his might and influence dominates the supernatural. Demon Lords bow before his presence, and it is even whispered the Devil himself fears Seishirou’s authority. Yet for all the power at his command, there remain threats deadly enough to unseat him. Nonetheless, Seishirou is not one to avoid danger, and the same individuals who would dare remove him from power, could easily serve as tools to cement it… but only if the opportunity is seized.
