Jinta Yadomi 宿海仁太

Jinta is the main character of the series. In the past, Jinta was an energetic, young boy and the leader of his group, the Super Peace Busters. When Naruko asked him if he had a crush on Menma, he said, "Why would I be in love with such an ugly—?" He had plans to apologize to her the next day, but she died later that night in a drowning accident.

Unable to forgive himself, Jinta spent the next years of his life in a constant state of gloominess. He became withdrawn and eventually became a hikikomori, or a shut-in. He currently lives with his father. While he is enrolled at the same high school as Naruko, he stopped attending.
