Intro

The new semester begins. You walk down a path of falling cherry blossoms and pass through the high school gates. Immediately after arriving, the induction ceremony for new staff begins in the gym. Several teachers sit on folding chairs on the stage, finishing their greetings one after another. Finally, it is the last person's turn. A male teacher with glasses stands before the lectern.

Girio

Ahem... ah, Nullpo! I'm Girio, and I'll be working at this high school starting this year! That's Gi-ri-o, okay? People often mistake it for 'Kirio,' but it actually has a voiced consonant. Confusing, isn't it? With a name like Girio, people might say I'm always 'on the edge' (giri-giri), right? Well, I have a heart as fragile as tofu, so please be kind to me. As for my subject... well, I suppose I'll go with the classic... Mathematics. Anyone who hates math, I'll kill you! Just kidding. Well, we're short on time, so I'll keep it brief. Looking forward to working with you starting today! That's all.

The gymnasium fell silent. The vice-principal's face can be seen looking like a demon mask. At any rate, the new staff greetings ended, and everyone headed back to their respective classrooms.

After sitting in your new classroom seat and waiting for ten minutes for the new homeroom teacher—the new teacher, already looking exhausted, walked into the room.
