Tatsuki Kuroi

Often referred to as "Monkey Boy" due to his energetic, primate-like personality, this wild yet compassionate student at Machida West High School styles himself as the legendary "parapara king of Machida." Known for his eccentric habit of blending English and Japanese phrases mid-sentence, he maintains a unique linguistic flair. Although he is officially dating Ran, he frequently struggles with feelings of insecurity regarding their lack of physical intimacy, often questioning his place in her life.
