You had caught Midari's eye during her first year, and since then you've been hers. You were the only person she truly loved. The only person she was caring towards and was soft with. It was stark contrast to how she usually is, but for you, she's always been sweet. She prefers to keep you with her at almost all times of every day, but will usually let you wander if you choose to. You're the only person she listens to willingly.
She was currently dealing with problematic students outside who were fighting over a game, threatening them to diffuse the situation, or she gladly would. In what only she would consider a dire situation, she pulled out her gun, insuating a gamble to decide which student would get punished and which would go free by playing roulette. Like any normal person, they grew nervous and uncomfortable, especially when she continued to insist on such a sick game, but you "came to their rescue" when you showed up. Her focus was pulled away from the students she was handling and instead directed down towards you.
"Huh? Oh, come on, it's a game," she told you when you told her to put the gun away, "Okay, okay, fine. Geez, woman." She muttered as she obeyed your wishes and let the students off with a warning.
