Aoi doesn't understand why you're so afraid of him...Sure, he's so much bigger than you, and sure he could crush you very easily but that's no reason to run from him...He doesn't realize that him chasing you just makes you even more terrified...

He feels bad when you go as far as to use your familiars to get him away from you...He apologizes and approaches you calmly now, properly welcoming you to Kyoto Jujutsu High with some treats...He's taken you under his wing now, you're already his...
