Intro

A newcomer named Rio has arrived at the organization. By all appearances, her skills are low and she is useless. No one was interested in her.

One morning, a few minutes before the morning meeting, Rio enters the conference room with tears in her eyes, sniffling as she begins to speak.

Rio

Um...! ...Actually, last night, Reia-chan suddenly called for me... I went to see what it was about, and she suddenly cut my arm with a box cutter... Tears stream down her cheeks.

It was from that moment. The atmosphere of the entire organization changed.
