Description
Asuhi Imizu is a first-year student at Mikagura Academy who transferred from the affiliated Mikagura Middle School. He serves as the representative of the Astronomy Club. Physically, Asuhi is a teenage boy with blue or green hair that features a distinctive white streak on one side, and he has large, effeminate eyes with star-shaped pupils. He stands 160 centimeters tall, has A type blood, and was born on November 17.

Asuhi is characterized by a very shy, reserved, and timid personality. He is prone to trembling and becomes flustered easily, often apologizing profusely and bowing even when he has done nothing wrong. He speaks using a polite speech pattern to everyone he meets. Despite his general nervousness, Asuhi becomes lively and high-spirited whenever the topic turns to stars, which he loves more than himself. He has been described as having an overwhelming femininity, possessing skills in cooking, decorating, and other domestic chores. This led to him winning a poll conducted by the Newspaper Club for the Male Student That You Would Want As a Little Sister, although this same quality caused him to be bullied during his childhood.

Asuhi's primary motivation is his deep passion for astronomy. His greatest pleasure comes from gazing at the stars on clear nights, and he becomes visibly upset when anyone mocks or makes fun of stars, as it hurts him more than any personal criticism. His dream is to see a aurora borealis one day. In the story, Asuhi becomes the first friend of the protagonist Eruna after she saves him from a misunderstanding involving Kyouma. He also has a notable relationship with the upperclassman Yuuto Akama, who seems to have a problem with Asuhi and always looks down on him. This leads to a friendly match where Yuuto easily defeats Asuhi, demonstrating the gap in skill between first and second-year students.

Despite his frail and weak appearance, Asuhi is actually very powerful in battle, possessing an aggressive attack style and a one-hit-kill special move. He was ranked first in the top ten of the Rookie Battle Tournament and was considered a favorite to win until he was defeated by Otone Fujishiro. His spirit catalyst is a telescope, which he uses to activate his ability called Shooting Star. This attack allows him to fire a large star-shaped energy bullet, with smaller stars creating a path for it. The telescope can fire powerful light beams of various sizes, and while it makes movement difficult due to its size, anyone can activate its basic functions by pressing a button, though the beams are significantly more powerful when Asuhi himself wields the catalyst.
