[2] At Keio Senior High School, 80 clubs are active in various fields such as academics, culture, and sports.

Keio University has inherited the “Source of Honorable Character and Model of Wisdom and Virtue” (character building through study) and “Independence and Self-Respect” (independence of mind and body and respect for self and others) to produce leaders for the entire society (Keio University's purpose).

A highly refined form of cheering has been established in the school through its history.

"Young Blood", "Titan," "Sirius," "Raging fire," and "Dash Keio" are some of the songs sung during the cheerleading.

The usual songs such as “We are the Champion” and “Blue Sky Keio” are omitted from this tournament's cheerleading.

The Keio University cheerleading team (Majorettes) performs two different songs in the Saturday games and the Sunday game (and later on if a game is carried over to Monday or later due to a tie or rain postponement since the Tokyo Big 6 University Baseball League of which Keio University belongs uses a point system) each in the spring and autumn league games, but the baton team of Keio Girls Senior High School only performs “A picture drew in the heart” as their repertoire.)

"Raging fire" It is an original song of Keio Senior High School and is played during the most exciting scenes in the game.
