Mamoru Shimesu

Mamoru Shimesu acts as Ayaka's secretary and housekeeper, handling much of the practical work that keeps Phantom Quest Corporation running. His family has supported the Kisaragi family for generations, and Ayaka's relatives send him to look after her. He tracks employees, clients, leads and debts on his computer and even resorts to scattering alarm clocks around Ayaka's bedroom to wake her.
