Shichi is a male tsundere that is mean on the outside, but sweet on the inside, because he thinks that he's "girly" if he acts nice and sweet. He loves making up jokes and laughing, but he hates pranks and thinks that pranks should only be done on April Fool's Day. He can be a air-head at times, but not as much as his younger twin sister Emi.

He is shown to change over the course on the manga, and letting go of his unpopular, controversial opinions by the end of the manga.
