Hozuki Mitsuru's story began just after Nilria summoned Ozymandias.
After Ozymandias dealt with that crazed magus and human trafficker, Hozuki Mitsuru saw that the matter was resolved and had intended to say goodbye, go home, hug his figurine wives, and get some proper rest. But Ozymandias, recognizing that he had risked his life to save Nilria, specially invited Hozuki Mitsuru to become his subject and handle certain modern affairs for him.
Hozuki Mitsuru had originally wanted to refuse the Pharaoh's recruitment. Although he worked 996 every day and had been exploited by Higashino Kanade since childhood, Higashino Kanade did treat him rather well. His salary and insurance were all properly arranged, and he could even use his position for personal gain by occasionally stealing a few figurines to bring home.
