Omake Gif Anime - 3-gatsu no Lion - Episode 30 - Hayashida Flicks Rei's Forehead

Mr. Hayashida used his formidable forehead flick to knock some perspective into Rei's worried forehead.

Mr. Hayashida felt the rage and frustration that Rei felt after hearing about Hina's awful homeroom teacher. The difference between them, however, is that Hayashida-sensei knows certain things as a teacher that Rei couldn't possibly know yet. His JoJo Stand is proof of that.
