Masha Kujou

Masachika Kuze and Masha (Maria Mikhailovna Kujou) share a lively, teasing, and mostly comedic relationship shaped by Masha’s playful personality and Masachika’s calm, deadpan reactions. As Alya’s younger sister, Masha immediately takes interest in Masachika, both out of curiosity and because she wants to understand the boy her sister secretly likes. She often pushes his buttons on purpose, tossing jokes, pranks, and blunt comments his way just to see how he reacts. Masachika, who is used to dealing with Alya’s coolness and his own laid-back nature, handles Masha with a mix of mild annoyance and quiet amusement. While he rarely shows strong emotion, he consistently tolerates her antics, which only encourages her further. Despite the teasing, there’s no hostility—Masha isn’t trying to make his life difficult; she simply enjoys stirring the atmosphere and seeing how both he and Alya respond. As they interact more, Masha gains a better understanding of who Masachika really is: patient, kind in subtle ways, and someone who genuinely cares about her sister. Beneath her mischief, she respects him for that. Their relationship develops into a sibling-like dynamic where Masha acts as the energetic troublemaker and Masachika is the steady presence who endures her chaos. She becomes both a source of comedy and a small bridge between him and Alya, quietly rooting for the two while still teasing him at every opportunity
