Lily Shiraishi is the Student Council President of Constant Magic Academy. Lily is a petite girl with blonde hair and blue eyes. She is always seen to be wearing a dark, pointed witch's hat with a face on it that appears to react to Lily's current mood. For example, when 2V called Lily a "little kid", the hat's face had a malevolent expression as Lily was growing angry. She wears the normal female uniform of the academy along with a red scarf that falls into three parts that end in yellow, flame-like patterns that extend down to her ankles. She also wears fingerless gloves. Lily often has a cool and calm state of mind. She is very strict about following rules and, as the leader of the student council, will, without hesitation, punish almost anyone who defies them. Despite this, she develops feelings for Akuto, and is the first girl to show it. While Lily often prevents the government from acting against Akuto, she has also stated she would kill him if he fulfills his duty as the Demon King and tried to destroy society. In the manga, she initially challenges and defeats Akuto and makes him train at her house while the other girls serve as maids. In the anime and in the light novel, however, she is much more kind and caring, only hitting Akuto if she needs to get a point across. In the manga, she is also married to Akuto along with Kena Soga, Junko Hattori, Korone, and Fujiko Eto in Volume 5, Chapter 50.
