Doumyouji Sakurako

Shuuma's classmate, playmate, and an inspiring person. Shuuma has known her for a long time, but she is not his childhood friend. After Shuuma pulled a prank on her, Sakurako became a "mayoler" (a mayonnaise lover) who thinks it's normal to drink mayonnaise straight.

Sakurako has many friends and is sociable. Naturally, she became friends with Calen who has a different standard from normal life, also with Aoi who is not a good conversationalist.

She is a rare person in that she talks with Shuuma in a natural way, even though every other female in the school is falling in love with him.

Lycoris turned her into a vampire by sucking her blood, causing Sakurako to attack Shuuma.
