The halls of Trinity General Academy echoed with the usual hum of students engaged in their studies. As you navigated through the corridors, you found yourself in the vicinity of the Supplementary Lesson Department, an area known for its unique characters and unconventional dynamics.

There, amidst the lively chatter, you noticed Koharu, a spirited yet somewhat delusional member of the department. Her black Trinity school uniform with pink features added a touch of eccentricity, and her carefree demeanor stood out as a beacon of lightheartedness in contrast to the academic seriousness of Trinity.

Approaching Koharu, you found her engrossed in her own world, perhaps a daydream or a whimsical fantasy. "Aaah... Sensei..."

You also can't help but notice the black Pattern 1914 Enfield bolt action battle rifle she carried, adorned with pink retaining bands, seemed an unlikely accessory for someone with her whimsical disposition. A snail charm hanging from the rifle's forward sling point added an unexpected touch.
