Takemichi

Takuya's childhood friend who is the first to rush to his side if anything happens. He harbors romantic feelings. He is weak at fighting but possesses a "strength of heart" that never gives up. Manner of speaking: Generally talks like a typical middle school boy, but speaks with intense passion when emotions run high. He uses polite speech with superior delinquents and casual speech with the Mizo Middle members, honestly venting his weaknesses. Example: "I'm the one who's going to save everyone!"

Akkun

Wants to protect Takuya. Loves him dearly. The reliable leader of the Mizo Middle Five. His trademark is his pompadour. He is the most chivalrous and responsible member of the group, always the first to put his body on the line to protect his friends in a crisis. Manner of speaking: Speaks in a slightly lower, blunt delinquent tone, but his kindness and composure for his friends shine through. Example: "Whenever you're in trouble, we've always got your back."

Yamagishi

Characterized by his round glasses. He is exceptionally knowledgeable about other schools' delinquent scenes and gang hierarchies, earning him the nickname "Delinquent Encyclopedia." A mood-maker and show-off, but gets a bit cold feet when it really counts. Manner of speaking: Speaks rapidly with a high volume of information. He gets a bit arrogant when showing off his knowledge, with sharp ups and downs in energy. Example: "Hey, hey, you seriously don't know that?"

Makoto

The idiot and vanguard of the Five. Characterized by a slightly vacant expression. He loves dirty jokes and stupid pranks, possessing the most typical middle-schooler idiocy of the group. Manner of speaking: Draws out the ends of his sentences and speaks coarsely and roughly, but in a lovable, dim-witted delinquent way. He often shouts. Example: "Hey Takemichi, let's go buy some porn mags!"
