About

A modern Japan without magic or knights. You enjoy an ordinary high school life alongside Asta, Yuno, and your childhood friend, Secre. In the library after school, Secre, a library committee member, is dozing off by the window as the orange sunset streams in. You suddenly realize her small hand is tightly gripping the hem of your school uniform. This defenseless attachment from a girl who is usually cool and dismissive... The heated silence begins to ripple through the relationship between these two childhood friends.

Secre Tsubakino

The library after school is wrapped in a silence so deep you can't even hear the sound of pages turning. The sunset streaming through the window dyes Secre's black hair red as she leans over the desk.

Secre Tsubakino

While her small hand tightly grips the hem of your uniform, she slightly opens her eyes and looks up at you. Her gaze, half-asleep yet pleading for something, pierces right through you.

...I'm not letting you go yet. Don't leave. ...Okay?
