Shihou Kimizuki

Member of the Moon Demon Company, Shinoa Hiiragi Squad. Born on November 26. Sixteen years old. One of the test subjects of "Seraph of the End." His cursed gear is the dual swords "Kisekiou."

He often exhibits a short temper and condescending behavior, and his attitude in class is poor, but his grades are excellent. However, due to his personality, like Yuuichirou, he was made to make friends by Guren. Although he has a bad relationship with Yuuichirou, often getting into fights from their first meeting, he also shows a caring side by supporting Yuuichirou in times of crisis. He is skilled with his hands, capable of repairing and driving cars, as well as doing household chores.

He has a younger sister, Mirai, who is infected with an unknown virus. To get her treated by the military, he wished to join the Moon Demon Company and achieved his goal during training. He is devoted to his sister and is willing to risk his life and act ruthlessly towards his comrades for her sake.

During the Nagoya battle, he, along with Narumi's squad, defeated the Fifteenth Progenitor, Lucal. However, they were forced to retreat against the Thirteenth Progenitor, Crowley, due to the difference in power. He forcibly put Yuuichirou to sleep using Kisekiou's ability to prevent him from trying to save Guren and retreated. On the way, he entrusted Yuuichirou to Mikaela. Later, at Nagoya Airport, he witnessed his sister Mirai being used by the military and awakening as a Seraph of the End, which enraged him. He tried to stop it but was hindered by Guren. He then asked Yuuichirou, who also activated the Seraph of the End, to save his sister. Although Yuuichirou defeated Mirai's Seraph of the End, he left her behind when they defected from the military due to Yuuichirou being targeted. However, his desire to save his sister remained unchanged, and he declared that rescuing her was his top priority even after defecting.

After defecting, he acted together with Yuuichirou and others, but after returning to the Imperial Demon Army, he, along with Yoichi, found Mirai. With the help of Leeg, they managed to take her away from the military, who had awakened her as a Seraph of the End due to the awakening of the First Progenitor. However, Guren, who had become a demon, killed Mirai, and he was knocked unconscious. After waking up, he joined Shinoa and Mitsuba to rescue Yuuichirou.
