Nakano, Itsuki

中野五月

Itsuki Nakano is the youngest of the Nakano Quintuplets. She is characterized as the "first girl" of the series. Itsuki is serious and hardworking, yet she is also a glutton and a crybaby.
Itsuki is a serious girl who usually wakes up earlier than her sisters. She also possesses good manners, to the extent that she places great importance on etiquette. She has never been late or skipped a class, and she always uses polite language.
Itsuki appears to be a girl who holds grudges, which is demonstrated when she rejects Fuutarou Uesugi's tutoring, partly due to their earlier dispute. She is also someone who struggles to be honest with herself and finds it difficult to be direct. Both of these traits often lead her to fight alone. Itsuki is often overly precise regarding the timing of cooking food.
Itsuki sometimes tends to be a crybaby, whether due to unfavorable situations, scary things, or her own stubbornness.
Itsuki has a large appetite and is frequently seen eating throughout the series. It seems she does not mind treating her sisters unfairly when it comes to food-related matters. When Itsuki proposes sharing their cakes, Ichika suspects that her true goal is to try all the flavors. Itsuki worries about Fuutarou, but this is actually because she is hungry.
According to Ichika, Fuutarou must be firm when dealing with Nino and kind when dealing with Itsuki.
