Tatsuki Mirei

Tatsuki Mirei (辰伎美麗) is a student of Tokiwadai Middle School who appears in Toaru Kagaku no Mental Out. She is one of the candidates for Tokiwadai's Student Council Election.

Appearance
Tatsuki has dark-colored hair, slightly parted at the center of her forehead, wearing rectangular glasses and a light-colored headband. Being a Tokiwadai student, she wears the school's uniform.

Personality
Tatsuki has exhibited a tendency for morbid remarks and voiced an apparent desire to dissect or stick things in peoples' brains. She also expressed a liking for Kumamori as a 'troll', and displayed similar behavior in addressing Iori with nicknames. She also supported prompt action and violence during the meeting between the election candidates. Like most of the other election candidates, Tatsuki was not willing to give up on her bid for student council presidency and support another's bid for the sake of stopping another one of her rivals.

Background
Tatsuki's background is mostly unknown, but she was established as a clique leader by the time of the student council presidential election.

Tokiwadai Election Arc
Tatsuki attended the meeting Kamino held with the other election candidates (with the exception of Inubushi, who ignored Kamino's invitation) about potential cooperation and courses of actions in response to their two main rivals in the competition joining forces, as Shokuhou Misaki and Gaouin Tsukasa were working together to find evidence that would exonerate Hokaze Junko.

She participated in the joint attack the candidates launched against Shokuhou and Gaouin, making her move when Iori Mashiro passed the baton to her after her own attacks missed.

Abilities
Her ability is currently unknown, but as a student of Tokiwadai Middle School, it can be presumed to be at Level 3 or 4. She appears to control liquid-based 'slimes', both multiple small ones and one larger one.
