Motto: "A database can't draw conclusions."

Satoshi went to the same middle school as Houtarou and Mayaka. He knows a lot of things, but most of all are trivial ones. He's really cheerful and a great match to befriend the apathetic Houtarou. He is really active, already being a part of the Student Council and Handicraft Club before joining the Classics Club. He is the "database" of the club and has a very good memory.
