Second Shibuya High School Arc
He first appears in chapter 5 during a meeting among the top-ranked members of the Japanese Imperial Demon Army.

Nagoya Arc

He informs Kureto that their father will not tolerate failure, but Kureto laughs and tells him their father can be angry in Hell. The two argue, and Kureto intimidates Seishirō. When Seishirō calls for backup from his soldiers, he sees that Kureto's aide and another soldier already took them down. Kureto's aide informs him that preparations are complete.

When Seishirō hears that Kureto is getting on a helicopter, he asks where Kureto is going and says the vampires are headed to Shinjuku to attack them. Kureto states he will imprison the vampires in Nagoya. Seishirō says he will report Kureto for defying their father, so Kureto draws his sword. Seishiro panics and begs for his life. Kureto says that Seishirō's obedience to those in power is useful, so he tells him to wait in the brig until he returns with "supreme power." Kureto does not explain his plans to Seishirō.
