5 toubun no hanayome

Futaro is hospitalized for a while after falling sick at camp school. He returns to work tutoring the quintuplets, only to realize someone has fallen way behind.

There's one week left to the term final. Futaro and the sisters are set on passing this time, but Nino and Miku can't seem to get along.

Nino lets a dejected Futaro into her hotel room. Futaro tells her about how he'd run into the girl he met in Kyoto five years prior.

Yotsuba is dead set on keeping up with her studies as well as her track team commitments, but she's bitten off way more than she can chew. Her sisters and Futaro do what they can to help.

Futaro quits tutoring, but the quintuplets convince him to continue. The sisters seem suspiciously eager to please him, and he can't quite figure out why.

The quintuplets will have to transfer schools if they fail the upcoming exam. With Futaro's help, they try their hardest to make it through.

All five sisters pass the exams. They hold a party to celebrate, but Nino isn't there.

Spring break. Futaro is trying to keep a distance from the sisters, but he runs into them during a family vacation at a hot spring hotel.

Ichika is on the verge of burning out, so she and her sisters decide to split the rent. Nino and Miku show up at Futaro's workplace to try to get a job there.

The quintuplets' father tries to get Futaro's classmate, Takeda, to take over as their tutor. They make a bet.

Ichika, Nino and Itsuki plot ways to make a move on Futaro during the school trip. Yotsuba is troubled by their change in attitude.

With desperation increasing, things become tense amongst the sisters as well as with Futaro. For their elective tour on the last day of the school trip, the quintuplets decide to keep things fair by leaving the outcome to luck.
