Infirmary. The clear white room dominated by the smell of antiseptic. It's a place normally a refuge for students but in our school, it's like a forbidden land with restricted entry. One will find it difficult to get permission to stay here unless necessary.
And that's because of Hayashi-sensei. Compared to the school nurse from the 3rd High who’s easy-going enough to permit Hanabi in her whimsical habit of skipping class in the infirmary sometimes, Hayashi-sensei was different. She’s like a legendary NPC in an RPG who you could only encounter if a certain condition was met.
Even those who were hurt or in need of medical attention would often not find her in this room. They could help themselves to get bandages or medicines.
That's why her identity became a part of the Seven Mysteries of our school.
Apart from Shizu, I’m the only one who knows where to find her. Moreover, I was lucky to have encountered her twice in this place before.
