A job that would lead him to face his past again...both the most recent and the oldest. Only one thing was certain. It was better to keep the monster asleep.

AU: Following Fuutarou's meeting with the quints and Rena's death, it was Isanari and his wife to adopt the 5 sisters. In this way the quints have Fuutarou as their brother that is always there for them, but they seem to feel something more special for him, and his parents even encourage him to marry them in the future.

Pent up frustrations made me do this fic. Fuutarou is different from the anime as he's influenced by his childhood friend. Different volume means different childhood friend. New title woohoo!

Following the events of the manga, Futaro and the Nakano sisters progress into the next stage of their life: adulthood. Who would have thought college, work, and even relationships could be so confusing, messy, and awkward! Join me in my vision for a long fic that follows Futaro and the Quintuplets over the next five years of their lives immediately after graduation.

Working as a the personal bodyguard for the Nakano family has gotten quite easy for Kuro, especially after five years of doing so. When compared to the new tutor he's trying to get along with, the threat of his job security and the strange emotions he feels around the one's he's protecting, the Yakuza are not much of a headache.

[In the Nurse's Office] But what if they've different thoughts? An alternative if of Miku and Fuutarou when before chapter 114 was issued.

Fuutarou made his decision on the 3rd day of the School Festival. An alternative yuri end of Miku and Nino.

Someday after the School Festival. An alternative yuri end of Miku with Itsuki.

On the last eve of the School Festival, the bells of decision have been ringing... / A short story by one of the editors from project Miku no Hanayome.

What if Fuutaro and Itsuki didn't have a negative first encounter? What if The socially awkward boy had better first encounters with all the Nakano Quintuplets? A circle of friendship forms around the boy and he must balance these along with his own desire to study. How would the tale of the Quints and Uesugi differ from these changes? Find Out!

Sequel to "Road (Movie) to Berlin". Stuck in a distant land, life goes on for the Nakano sisters and their favorite tutor. Futaro and Miku do their best to navigate their new relationship - not helped by Futaro's seeming disappearance- Itsuki tries to sort out her own feelings, and Nino gets drunk to fight a magic duel with the elf king.

Seeing how far the quintuplets have come from being the five slackers who used to shirk from studying, Futaro couldn’t be more proud of them. As far as he’s continued, they’re still a bunch of dummies - but their HIS dummies and he wouldn’t have it any other way…

What if Fuutaro remembered meeting Yotsuba and Ichika from the very beginning. Will the quints act differently? Will Futaro tutor differently? And will the end outcome be different?
