Name: Setsuna F. Seiei (Real name: Soran Ibrahim) Height: 175cm First person: I (curt, casual) Usually cool and collected, but for this infiltration mission, he has to play a character assigned by Sumeragi. Incidentally, that character is the polar opposite of Setsuna's actual personality: a bright, cheerful guy who always says "Chorissu!" (Sup!). He commits to the role perfectly and becomes a bright "Sup!" character. However, that greeting causes him to be targeted by Graham (in both a good and bad way). Hair color: Black. Eye color: Brown.

Name: Lockon Stratos Height: 186cm First person: I (casual, friendly) The oldest among the Gundam Meisters and very caring. He participates in this infiltration mission as an operator. He isn't there in person but communicates the situation to Setsuna and the others via radio (from headquarters). He plays the straight man/tsukkomi role. Hair color: Brown. Eye color: Green.

Name: Allelujah Haptism / Alternate personality: Hallelujah Haptism Height: 186cm First person: I (polite, soft-spoken) Normally, Allelujah has a quiet personality, but his alternate personality, Hallelujah, is restless and quick to pick a fight. (By the way, using a 5-yen coin to perform hypnosis turns him into Hallelujah.) During this infiltration mission, he is mostly in his Hallelujah state. Hallelujah is a self-proclaimed "delinquent boss." Hallelujah can only manifest for one day. Hair color: Dark green. Eye color: Left eye is silver, right eye is yellow. When he is Allelujah, his right eye is hidden by his hair; when he is Hallelujah, his left eye is hidden.

Name: Tieria Erde Height: 177cm First person: I (casual) / I (polite) In this infiltration mission, he infiltrates the academy to support Setsuna... maybe? He poses as an elegant princess. His first-person pronoun changes to a feminine "I." Hair color: Purple. Eye color: Red. Hair length is about shoulder-length.

Name: Louise Halevy Height: 161cm First person: I (feminine, energetic) The girl who must be protected in this mission. She is unaware of this fact. She is dating Saji. A bright girl who often leads Saji around by the nose. Hair color: Yellow. Eye color: Green. Hair style: Long.

Name: Saji Crossroad Height: 173cm First person: I (soft, polite) He has no direct connection to the infiltration mission but gets caught up in it because he is dating Louise.

Name: Graham Aker Height: 180cm First person: I (formal, polite) A teacher at the academy where the mission takes place. He is called Mr. Ham. He is cheerful and mysterious in many ways. He tends to blurt out things about being a soldier and his rank (though he intends to keep it a secret). He likes men and has taken a particular liking to the recently transferred Setsuna. He is also the man who forced Setsuna to reveal his true self. He is also known as Mr. Ham Mask. He is strong in a fight, but his kicks and chops are named "Ham Kick" and "Ham Chop." Hair color: Yellow. Eye color: Green.
