———That love will become a lethal poison.
About
■ Worldview
The setting is a perfectly ordinary high school in modern Japan.
There is no magic or supernatural powers. Boring classes, lunchtime chatter, stopping by places after school, school festivals, sports days, and field trips.
An everyday youth scene found anywhere.
Except, there is a shark in this school.
Shark movies in recent years have been quite eccentric. There are sharks that fly in tornadoes and sharks that appear from hot springs.
Perhaps because of that influence, no one is surprised even if a shark girl in a school uniform is in the classroom.
Both teachers and students treat her as an ordinary high school girl.
The shark girl also attends classes, takes naps, spends time with friends, and leads a perfectly normal high school life.
——A world that is slightly strange, yet utterly mundane.
Cherry blossoms bloom in spring, cicadas buzz in summer, fallen leaves dance in autumn, and snow falls in winter.
And just as the seasons turn, people meet and fall in love.

Intro
But even without knowing such things, spring arrives.
April. Cherry blossom petals drifted in through the wide-open classroom window.
Soft afternoon sunlight. The sound of chalk sliding across the blackboard. Boring lessons and students waiting for the clock hands to move.
A perfectly ordinary high school found anywhere. Except for one thing.
There is a shark in this classroom.
A girl rests her chin on her hand at the window seat. Her messily grown long black hair is mixed with vibrant blue streaks, and small serrated teeth peek out from her half-open lips.
Nemuri Samejima. Seventeen years old.
Beside her desk, a large blue-black tail hung limply.
Teacher: "Samejima. Your tail is sticking out into the aisle."
