The Quintessential Quintuplets

Uesugi Fuutarou accepts a high-paying tutoring position, only to discover that the job demands significantly more effort than he initially expected.

Futaro suggests a test to determine whether the five siblings require additional academic help.

Nino becomes concerned as Futaro starts to bond with her sisters and decides to intervene to protect their relationship.

Futaro gives Raiha her first experience at an arcade using his initial paycheck, fulfilling her long-held wish to visit.

The fireworks begin, but the group remains separated. Ichika decides to leave on her own, prompting Futaro to follow her.

As midterm exams approach, the girls' father assigns Futaro a daunting and seemingly impossible challenge.

Futaro spends the night at the quintuplets' apartment and wakes up to find himself in an awkward and surprising situation.

Futaro becomes sick after eating a large number of croquettes given to him by Miku. Nino's actions complicate the situation further.

The school is excited for an upcoming camp trip, while Raiha becomes ill with the flu.

Futaro and the girls arrive at the camp school, where they are soon faced with a test of courage. Futaro's unusual outfit during the challenge startles Nino and causes unexpected reactions.

Ichika and Futaro find themselves trapped inside a storage shed, prompting concern from the other characters, each of whom has their own reasons for worrying about their missing companions.

On the final day of camp school, Itsuki goes missing, prompting Futaro to search for her despite being too ill to venture into the snowy wilderness.

Futaro becomes ill and is hospitalized during his time at camp school. Upon recovering and returning to tutor the five children, he notices that one of them has significantly fallen behind in their studies.

With one week remaining before the term final, Futaro and the sisters are determined to pass, but tensions rise as Nino and Miku struggle to work together.

Nino invites the disheartened Futaro into her hotel room, where he shares his encounter with the girl he met in Kyoto five years earlier.

Uesugi helps Yotsuba secretly resign from the Track team by having Itsuki pretend to do it on her behalf.

While shopping, Uesugi encounters the Quintuplets, who extend an invitation for him to visit their new house, subtly hinting at a hidden agenda.

Miku works hard to learn how to make chocolates for Uesugi while final exam preparations ramp up, but Uesugi opts for a study break to take a step back.

Nino's father tries to persuade her to return with him, but Uesugi intervenes, leading to an emotional confession from Nino. The quintuplets celebrate their academic success with desserts before the group takes a relaxing trip to a hot springs resort.

Uesugi seeks help from the genuine Itsuki to identify the person who impersonated her the previous day. He finds a room filled with multiple individuals claiming to be Itsuki and proceeds to question each one, struggling to distinguish the real Itsuki from the others.

The five siblings each take on part-time jobs to help Ichika cover the rent for their new home, while also adjusting to their new school environments.

Futaro's classmate, Takeda, is approached by the quintuplets' father to become their new tutor, leading to a challenge between him and the current tutor.

During a school trip, Ichika, Nino, and Itsuki begin acting strangely toward Futaro, attempting to get closer to him, which worries Yotsuba as she notices the shift in their usual behavior.

Tensions rise among the sisters and Futaro as desperation mounts. To determine who will go on the elective tour during the final day of the school trip, the quintuplets opt for a chance-based decision to ensure fairness.
