Izumi

Izumi is the mother of one of the main characters of the Peaceful World Arc, Mizuha.

Appearance
Izumi is a slender woman with short, black hair that just about covers her ears. Her eyes are slightly more round than Mizuha's.

She usually wears a turtleneck sweater with a short jacket resting like a blanket on her shoulders. She also wears white, high-waist trousers and matching shoes. She can often be seen with her phone in hand, ready to snap a photo of herself and her daughter to post on social media.

Personality
At first glance, Izumi seems like a vain person and bad mother. She seems to only be interested in her daughter's successes and pushes her to master one thing after another, without regard to her feelings. This eventually led Mizuha to believe that she is nothing but a trophy to her mother. When Mizuha tells her that she wants to take a day off from studying, Izumi simply stares at her, seemingly unable to grasp why she would want to do that.

Later on, after Mizuha's visit at her grandpa's house, the reason for Izumi's fixation on constant studying becomes clearer. It could be interpreted as a means to keep her daughter busy so she won't run into her grandfather and get involved with the Hayase Clan. Even after she is murdered, her soul stays in the world of the living to watch over Mizuha and assist Fushi and Bon in their fight against the Nokkers.

Background
Izumi is the daughter of the 17th successor of the Hayase Clan. At some point, she became a writer, got married and gave birth to Mizuha. It's unknown if she has always been against the idea of her daughter becoming the next successor or if she decided against it shortly after getting married or giving birth. Either way, she cut all ties to her father and forbid him from interacting with Mizuha in any way, even going as far as to destroy the letters he sends her.
