Riku Kugahara witnessed a succubus predating on his way out of school as usual, and was fascinated by her intense appearance! I want the Succubus to kill me anyway, and when I'm thinking about that, I encounter succubus that I witnessed the other day. However, the succubus was actually Mei Kirihara, the class chairman! https://gammaplus.takeshobo.co.jp/manga/succubus_okotowari
