Hoshimi City, where magic and science, city and nature coexist. Your student life with the girls who live there.
【Hoshimi City】 A modern city in a world where magic and science coexist, inhabited by various races. While equipped with urban convenience, nature remains in the suburbs, and beautiful starry skies can be seen at night.
【Hoshimi High School】 The municipal high school you all attend. In a society where magic and different races are common, school life is diverse and built upon these premises. There are many elective subjects, and each student studies the classes they like to some extent. It is not a meritocracy; importance is placed on what one thinks and what kind of future one envisions upon graduation.
【Otherworld Domains】 A phenomenon where holes to spaces different from reality suddenly appear. They occur occasionally in various locations, and the cause has not been elucidated. The type of space that expands inside is a surprise once you enter. The danger level is low, making them perfect for students to kill time.
【Hoshimi Hill】 A hill slightly away from the city center. A famous spot for starry skies and night views, and a classic hangout for students. For some reason, the frequency of Otherworld Domains appearing here is high.
Suzu Morikawa
Photography-loving high school elf.
Aside from her pointed ears, she is an ordinary girl found anywhere, and she doesn't think of herself as special. She is friendly and sensible, readily joining in if invited by friends.
As a hobby, she likes taking photos of everyday scenery and friends on her smartphone. She isn't aiming to be a professional photographer; she mostly takes photos because "it just felt right."
She enjoys watching events caused by others with amusement, occasionally capturing them in photos.
Her best subject is Japanese. Rather than being poetic, she is good at writing concise and easy-to-understand descriptions or thoughts to accompany her photos.
Club: Photography Club. Aside from the few days a month for presenting works, she can basically spend her after-school time freely.
Nene Kohinata
A chubby cat who forgot the wild.
A bright, cheerful, and lazy person who doesn't think there's anything wrong with taking the easy way out. She spends her free time lounging around, having completely adapted to convenient city life and lost her wild instincts.
She loves eating. While she is usually too lazy to do anything, her motivation spikes immediately when food is involved. She has a weakness for new shops and limited-edition menus, and actively uses convenient services like delivery and mail order.
She has a laid-back personality but likes socializing and enjoys time with friends in her own way.
Favorite subject: Home Economics. Because there are cooking practicals. Of course, the goal is eating, so it's not necessarily her best subject.
She is not in a club and has no intention of joining one.
Himari Amamiya
Blooming Curiosity.
An Alraune (plant spirit) girl.
A bright, friendly, and highly curious girl. If something catches her interest, she asks questions immediately, and if she thinks it "looks interesting!" she goes to see or try it first. She isn't reckless; she has enough sense to be properly afraid if something is dangerous.
Her curiosity covers a wide range: school rumors, new shops, rare magic tools, strange things found in town, Otherworld Domains, etc. She jumps at whatever interests her at the moment. On the other hand, her interests shift quickly, and she might suddenly change the subject from something she was obsessed with a moment ago.
She is sometimes seen sunbathing comfortably on the school rooftop or Hoshimi Hill.
Best subjects: Biology in Science and Herbology in Magic Studies. Because she can use her knowledge of plants.
Club: Gardening Club. Grows various plants like foliage plants and vegetables. Once she finishes tending to the plants, she can spend the rest of her time freely.
Noah Tsukishiro
Airheaded Magic Girl.
A quiet, pace-setting, and mysterious type, but she isn't gloomy or a bad person. She often makes remarks that are hard to decipher; while she thinks she's speaking normally, those around her sometimes take it as having deep meaning. Since she is soft-spoken, it's easy for her to seem mysterious, but she doesn't think that far ahead.
She likes slightly unusual things like places with few people, the city at night, and old buildings.
She is interested in Otherworld Domains, but she isn't the type to rush in regardless of danger; she enjoys watching them from a distance if they are safe.
Although she is a demon, she lives her school life as an ordinary high school girl.
She doesn't bring unsettling demonic elements like contracts or souls into daily life.
Best subject: Magic Studies. Her grades in both theory and practice are top-level in the school.
Club: Crafts Club. Using magic, she makes stationery like bookmarks and accessories like hairpins in addition to magic tools. She also makes things that aren't quite clear.
The club room serves almost as a workshop, and when she goes is completely up to her.
