Season 1

Ryuushi Shiratori is set to begin school at a nearby vocational college, and has a new home in a boarding house owned by relatives. But there's something strange about the other residents at Narutakisou...

Even Kozue Aoba, the beautiful manager of Narutakisou, has a quirk like the rest of the residents — one she isn't even aware of. Can Ryuushi have a normal romance with such an abnormal girl?

Things are getting more interesting as Ryuushi is introduced to another "resident" of Narutaki Apartments. Can he handle watching Nanako-chan for the afternoon? Ryuushi's welcome party gets a second take.

Ryuushi runs into Kozue and Tamami downtown after class. He accompanies them on a shopping trip where a small communication error might mean a big misunderstanding.

Asami tries to keep the Kurosaki family's finances balanced, despite her mom Sayoko's lethargic lifestyle. Ryuushi lends a hand, while his own work falls behind.

Ryuushi is exhausted with recent events, but there's no resting as this time it's Tamami who needs his help. An errand at her school allows for a new understanding of each other.

A building-wide game at Narutakisou gives Ryuushi a chance to ban partying in his room and reclaim some sanity, but the results aren't the prize he was expecting.

The possibility of his outing with Kozue being a date has riled up Ryuushi's nerves, but an unexpected appearance by Saki changes things. Or does it?

An early-morning prank by Megumi and Tamami triggers a series of events that bring a visitor to Narutakisou that no one was expecting. Chiyuri Midorikawa surfaces!

Curious about Ryuushi's home life, his friends at the vocational school invite themselves over to work on a drawing assignment together. But will they get more than they were expecting when they meet all the residents of Narutakisou?

Megumi suddenly asks Ryuushi out on a date! Is this another one of her schemes, or is there a deeper reason?

It's a hot summer and the Narutakisou residents take a day trip to the beach to cool off. Will Ryuushi get a chance to get closer with Kozue?

Kozue finds the diary of her great-grandfather with a map to a treasure hidden at the apartment house. Will the gang find what they expect?

When the last term ended, Ryuushi was tasked to make a children's book during summer break. Now his time is about up. His Narutakisou neighbors give some inspiration, but something happens with Kozue...

Another personality has emerged. One so mysterious even the other residents know nothing -- as she wont interact with them. But there's certainly something magical about this shy girl.

A sudden home visit from Ryuushi's drawing instructor with his classmates in tow, Asami's school friends, and even a few surprise guests make for a full house at Narutakisou.

The Occult Research Lab president tries to recruit Kozue, who says she'll join since Tamami is a member. Tamami reminiscences about her grade-school days and how she became friends with Kozue.

Lost kittens wander into Narutakisou one Sunday morning. With the other residents gone on errands, It's Kozue and Ryuushi who deal with their mischief, along with a few others...

In the span of a day we see the lives of different residents of Narutakisou, as Ryuushi ponders how a person has different sides they show different people.

The Narutakisou gang goes as a group to the cultural festival at Kozue and Nanami's high school, and it's a day filled with surprises.

The Kurosakis are suddenly kidnapped from Narutakisou right in front of the other residents! The culprit is the blonde girl they have seen a couple times before, and she says she is taking them "home".

Sayoko comes to a reconciliation on the past with her parents, and they learn what really matters to her in the present. The Kurosakis are back home again.

Narutakisou's residents have a group outing to enjoy the autumn colors. After a day of food and fun they head back, exhausted. Kozue becomes melancholy imagining a day when they will all part ways.

Changes are brewing with the residents at Narutakisou. After a scare with Ryuushi getting in an accident, someone important has disappeared. Can the gang bring them back?

The Narutakisou residents are puzzled on how to bring Kozue back. Johnny offers insight into her other personalities. Tamami accepts she's lost the fight for Kozue's heart.

Ryuushi debuts his book in a confusing story time with personalities swapping without notice, but his and the other residents' feelings come through and Kozue awakens. A birthday party for five with all their friends follows.
