Kei Yamori

Kei Yamori (ケイ) is Kou Yamori's mother. She gave birth and got married at the age of twenty and got a divorce when her husband cheated on her. From that point on, she has been raising Kou as a single mother and works in the night entertainment industry.

Appearance
Kei is an attractive woman with a relatively short build. She has long, bright hair that she wears loose. Her eyes with small pupils are identical to those of her son, and she is shown to wear glasses at home occasionally. Her left ear is exposed and features an earring.

While at work, she wears outfits typical for hostesses, such as a long-sleeved shirt with frills at the hips and a pencil skirt. At home, she wears a long sweatshirt that ends just above her knees.

Personality
In her first appearance, Kei shows a relaxed demeanor. Despite caring and being concerned about Kou, Kei doesn't mind him skipping school and walking around at night, believing she has no right to act like a "proper parent" because she spends little time with him due to the nature of her job, thinking that she is a bad mother.

She can be hot-tempered, like when, on two occasions, someone came to talk to Kou, and he kept them waiting because he was sleeping. In those situations, she isn't above hurling insults at her son. Kei also doesn't give Kou presents for Christmas, asking why he should get anything if she doesn't.

Abilities
As an average human, Kei doesn't possess any kind of extraordinary ability.

Trivia

 * Her height seems to be inconsistent. In one panel she is shown to be shorter than Kou while in another panel it seems like she is taller than Akira, who is generally shown to be taller than Kou. The most likely explanation for this (Aside from inconsistency by Kotoyama) would be her wearing shoes with heels.
 * Like Kou, she became a dropout after middle school.
