Hana, a high-schooler that is known as the cutest girl in school, gets pulled into a supernatural event while on a beach trip with her friends. This event, called a "Red Night Eve" involves a transformed extremely massive shark, which targets Hana while she's swimming! Luckily, she's rescued by the siblings Yayako and Yuuto Kagimori, students from her school who know all about these occurrences, and who even have a support program AI named Acacia in their tablet to help them. Not long after, Hana and the siblings are involved in another event, this time involving her precious class pet parakeet being transformed into something monstrous. With all these supernatural events, Hana's life is never going to be the same!

My first impression of Ryuuga was “This is the kind of protagonist you’d see in something like an anime.” Then, that thought soon changed into conviction. First of all, this guy almost never talks about his past. Also, he frequently slips out of class. As soon as he comes back, he gets extremely tired, blood comes out from his lips, the sleeves and cuffs of his uniform get torn, and so forth. Furthermore, there’s always beauties that are surrounding Ryuuga. The one who’s like an idol within the school, Yukimiya Shiori. The cool expert of the sword, Aogasaki Rei. The mysterious transfer student, Elmira McCartney. It’s very tiring for me when these people appear in front of Ryuuga. I have to frantically make a fuss by saying things like “H, hey Ryuga! How did you get acquainted with Yukimiya!”, “W, why did the beautiful swordswoman Aogasaki come to the classroom to specifically meet Ryuga?!”, or “E, E, Elmira! What is it that you see in Ryuga!” …So why am I doing this? That’s because I, Kobayashi Ichirou, am a pro at being a friend. My life’s calling is to support Hinomori Ryuuga, the protagonist amongst protagonists, as a close friend character. ―Let the curtains open for the rom-com presented by co-starring best friend, Kobayashi Ichirou!

It's about an odd girl doing odd things.
