First Shibuya High School

First Shibuya High School (第一渋谷高校) is an upper-secondary school located in Shibuya that Guren Ichinose attends when he is sixteen. It is run by the religious sect known as the Order of the Imperial Demons led by the Hīragi Family. The school specializes in training magic users and is unknown to the public.

As a school for the elite, only the best and brightest of students are chosen to attend from adherents throughout Japan, with nearly every student being the son or daughter of a clan that belongs to the Order and believes in its teachings.

The school is one of the settings in the Seraph of the End: Guren Ichinose: Catastrophe at Sixteen light novel series before the apocalypse occurs.
