Seri Kikiyou

Seri Kikyou (セリ) is a side character in Call of the Night. She is a a gyaru who seeks enjoyment in life and finds it increasingly challenging to have fun.

Appearance
An attractive, young-looking girl with blonde hair but a brown root, golden eyes, and pink lips, wearing a school uniform consisting of a white t-shirt, a sandy brown sweater, a dark blue skirt and socks, and brown loafers. Under her shirt, she wears a tiny chain necklace and a purple bra; her left ear has four piercings.

Personality
She acts similarly to a typical gyaru. She is very carefree and loves having fun and flirting, a hobby in which she displays great confidence, shown when she casually reveals her cleavage to Kou when she notices that he is staring at her. Seri is a fan of modern and trendy things and isn't too fond of retro stuff, although she can be relatively open-minded.

She is incredibly ruthless and doesn't hesitate to kill someone if she has a reason to, something she apparently did multiple times in the past.

Seri admitted that flirting stopped being fun to her and that people stopped turning her on. The men she chooses as servant candidates eventually all end up the same, irrational, possessive, and attention-seeking. Despite mentioning that vampires can't be friends with humans, she wanted to have a platonic friendship with someone but subconsciously flirted with them and wanted to make him like her because she had no experience in a normal friendship. When she tried to end the relationship, she started to cry because of the fun she had.

Kou Yamori
Seri and Kou first met when Kou was taking shelter from the rain. After spotting him, they would sit next to each other, and Seri talked to Kou about her lifestyle. When Kou could sympathize with her problems, she embraced him and almost sucked his blood. After getting stopped by Nazuna, she declared how she would kill Kou since humans mustn't know about the existence of vampires, which served as a distraction so that Kabura could kidnap Kou. Later, Seri was still on good terms with Kou, finding him sympathetic, sharing her worries with him, and singing karaoke with him, but she didn't hesitate to try to kill Kou again when he defended Akkun.

Akihito Akiyama
She met Akihito after he got dumped. They would talk, and Seri was intrigued by Akihito's disregard for romance relating to him. However, she still ended up making him fall in love with her, leading to Akihito becoming obsessed with her and Seri cutting him off. When they met again, she saw him as a nuisance and tried to kill him, unsuccessfully, because of Nazuna's and Kou's interference. After partially confessing what happened, she proposed to Akihito that they stop meeting for the sake of them both. Kou said she wanted to kill him because she didn't want to lose him as a friend. Seri explained to Akihito that humans are either servants or food for vampires and that she couldn't hang out with him because of that and started to cry because of it.

After turning him into a vampire, they would almost always appear as a duo, and she was shown to care a lot about him, being very upset when he got injured by Anko and promising to make new memories with him when Akihito got rid of his weakness from his human past.

Nazuna Nanakusa
Seri's and Nazuna's relationship is defined by animosity from both sides. She scolded Nazuna for hanging around with a human, telling her that she should create offspring (servants). Nazuna then aggressively fought her and left her in a very damaged state. They fought again when Nazuna brutally kicked her in the face when Seri approached Kou later, to which Seri reacted by punching Nazuna's head, causing both of them to go ham and throw insults at each other. Seri later asked Nazuna why she didn't tell anyone about Anko's true identity after Anko heavily injured Akkun. She was very surprised when Nazuna showed noticeable growth when she took responsibility for what happened.

Abilities

 * Vampiric abilities: Like all vampires, Seri has superhuman strength and speed, can regenerate and quickly recover from a injury that would be incredibly dangerous for a human and levitate.
 * Pain endurance: When Nazuna cut off her arm, she kept her composure and wasn't too affected by it.

Trivia

 * Like many other Komori vampires, she is named after one of the seven herbs of spring, Japanese parsley or seri (セリ).
