Kirara Mizutani

Kirara Mizutani (水谷 きらら Mizutani Kirara) was one of the Otherworlders summoned to serve Falmuth.

Personality
Kirara was a self-centered individual who always blame everyone else but herself. She tried to convince herself that none of the things in the new world matter, she just had to go back home which is why everyone she has killed doesn't bother her one bit.

Much like Shogo Taguchi, Kirara was shown to have similarly strong feelings of resentment for her being summoned into the Other world and being forced to become a human weapon for the Kingdom and due to her actively not wanting to care about anything in the new world or being all that attached to the people of the new world, Kirara has shown to blatantly declared that the world itself should be destroyed.

Due to her apathy and resentment for the Kingdom of Falmuth, Kirara herself has shown to not really put too much effort into actually helping the Kingdom unless ordered to.

However despite her largely amoral and apathetic view of the new world she was summoned to and its natives, Kirara was hinted to hate them due to her greatly missing her home and family in her Original world. This is seen where she called out to her mother in her final moments upon being killed by Shogo.

Background
Kirara was still young, aged eighteen when she had been summoned into Falmuth-controlled land three years prior to attacking Tempest. Her skill—which involved influencing people's thoughts during negotiation—wasn't directly related to battle, which led to rough treatment and assumptions that she was just another failed summons at first.

Kirara then massacred all of her summoners until she was finally put down under a locking curse. Ever since, Kirara's skill had been sealed away, restricted from activating without permission.

Story
Kirara was ordered to provoke Jura Tempest Federation together with Shogo Taguchi and Kyoya Tachibana and managed to kill several of Tempest's citizens. She initially wanted to provoke the town's guard by falsely accusing Gobzo, but was stopped by Gobta and Shuna. She was very shocked when Shuna cancelled her unique skill, as she thought that no one was able to do that.

Later on, she was killed by Shogo in her camp because Shogo needed more power to defeat Geld.

Unique Skill

 * Bewilder: Kirara's unique skill obtained after being summoned. This Skill allows Kirara to directly send commands to her victims brains through her voice, allowing her to forcibly take control of them and force them to do her bidding. This skill was noted to be powerful and the overall range of it allowed her to compel anyone within earshot of her voice, with Kirara having forced all of the mages present in her summoning ritual to commit mass suicide by simply saying "die".

Etymology

 * Kirara's surname Mizutani means "water" (水) (mizu) and "valley" (谷) (tani).

Trivia

 * Kirara's death was not shown or specified in the manga and lightnovel, but it was in the Anime.
