Overview: Haruka thinks that without his ability to see microbes, there is not much reason for him to be at the university anymore, though Kaoru and Takuma stick up for him. Tadayasu seeks advice from Kei, and in the process finds out that despite Kei getting mad in the past for being called feminine, he decided that deep down he was not being entirely honest with himself about his gender identity. Haruka reconciles with Tadayasu later, and at that time Tadayasu regains the ability to see microbes once more.
