Koharu Otori (鳳 小春, Ōtori Koharu?) is one of the main characters in the series. She is a third year student and the president of the Astronomy Club who later starts going out with Shouma Akiyama.


Koharu is a small and petite looking girl who is often said to be beautiful and rabbit-like with long and somewhat wavy light bluish-white hair that has bangs hanging over her eyebrows and blue eyes. She usually wears her school uniform with an orange bunny hoodie over the top.

Despite being the lolita character, she is actually in her third year.


Koharu is often described as rabbit-like girl who has a graceful personality.

She is revealed to be in love with Shouma Akiyama as she is shown to have taken photos of Shouma and she appears to be somewhat of a stalker who goes as far as blackmailing Keiki Kiryuu into helping her get close to his best friend or act as the "cupid" for them as Otori describes.


Shouma Akiyama

Koharu is in love with Shouma as he plucked her hat ; that had blown onto a tree, out of the tree. However she is too shy to talk to him and instead stalks him and takes many photos of him. She is aware of Shouma's lolita tastes but thinks he won't accept her because she is older than him, but they do eventually start to date.

Keiki Kiryuu

Koharu has a friendly relationship with Keiki as he has been forced to be the middle man or the "cupid" that will bring Koharu and Shouma Akiyama together. She didn't know how else to get Keiki's help so she blackmailed him with a photo she took of him and Sayuki Tokihara.
