A place to call home,
Was made before I knew it.

Maison Fleur

SCROLL
Spring, a new life begins.

Spring.
To start a new life,
You opened the door to "Maison Fleur".

A three-story apartment building, aged just a little.
Ivy climbs the exterior walls,
And seasonal flowers greet the residents.

A greeting as you pass in the hallway.
The sounds of life from the next room.
A warm meal shared with someone.

As the ordinary days pile up,
This place gradually becomes
Your "home to return to".

小野節子
Landlady, Setsuko Ono

"It's a bit old, you know.
But most of the residents are young people."

Each room, their own daily life.

Room 301
岩井俊一
Novelist

Shunichi Iwai

35 years old

Today too, from room 301,
The aroma of coffee drifts quietly.

Calm and a good listener.
Someone who doesn't rush you for an answer,
And quietly stays by your side when needed.

Room 201
亀山慶太
VTuber

Keita Kameyama

25 years old

Today too, from room 201,
A cheerful "ton ton ton" can be heard.

A neighbor who's a bit bad at socializing.
In front of someone they feel comfortable with,
They show a genuine smile.

Room 302
松下慎太郎
Science student / Host

Shintaro Matsushita

22 years old

When he comes home,
He falls asleep on the sofa.

A mood maker who loves to make people laugh.
Good at supporting others,
But not so good at relying on them himself.

Landlady's?

Construction Industry Worker

Masaaki Ono

33 years old

The tough-looking guy
Is petting a cat, as always.

He may have a rough mouth, but he can't ignore someone in trouble.
Shows his kindness through actions rather than words,
A reliable older brother figure.

From Setsuko-san

"He's my proud grandson! Isn't he cute?"

Each room, their own story.
Whose door will you knock on?

Ask Setsuko!

Welcome to the Manager's Room
Setsuko Ono
Landlady, Setsuko Ono

"Oh my, oh my.
Let's have some tea and chat, shall we?
If you have any troubles, please ask me anything."

Letter from a Resident

"Setsuko-san, what should I do first?"

👵

"First, I recommend heading to the entrance hall.
Going to the nearby convenience store for shopping is also good.
Since it's a place where people come and go, you'll often bump into other residents.

If you find someone you're interested in, try visiting their room or stopping by their door for a bit.
As you see each other more often, everyone will gradually open up."

Living Tips

When You Want to Meet Residents

The residents of Maison Fleur each spend their time with work, school, or their own personal activities. Not everyone is always gathered in the same place.

When you want to meet someone

"Head to the entrance hall."
"Go to the nearby convenience store for shopping."

When you're interested in a resident

"Visit Iwai-san's room."
"Stop by Shintaro's room."

When you want to peek into another side of a resident

"Watch Keita's stream."
"Read Iwai-san's novel."
"Go to the host club where Shintaro works."

The exact wording doesn't matter. If you write in the chat where you want to go or what you want to do, the story will begin to unfold from there.

Whether you're looking for love or just enjoying the everyday lives of the residents, it's up to you.
Your "What should I do today?" will become the story of Maison Fleur.

Letter from a Resident

"How do I interact with residents who are in their rooms?"

👵

"Keita seems to be doing game streams, or something like that.
I haven't seen it myself, but many people seem to enjoy it.

If you type 'Watch Keita's stream' in the chat, you might be able to peek in on Keita while he's streaming.
Apparently, he has a slightly different vibe than the Keita you usually meet in the apartment."

"How do I play seasonal events?"

👵

"This apartment doesn't have a set order for events, like 'what's next!'
'Maybe I'll go cherry blossom viewing today,' or 'Perhaps I'll invite them to a fireworks festival this time.'
Enjoy the seasons at your own pace like that."

Letter from a Resident

"Setsuko-san, how can I meet your grandson?"

👵

"About Ma-kun?
He's busy with work, so he's not here every day.
But he visits this apartment every week.
You might see him in the entrance hall or the garden, so say hello if you do.
He might look a bit intimidating, but he's a very kind boy."

Letter from a Resident

"What kind of person should I be when I move in?"

👵

"If you're unsure, I've written down some recommendations.
But the most important thing is to enjoy yourself as you are.
Become the person you like and try living in this apartment."

Recommended Personas

Recommended: A working adult in their mid-20s who has moved to this town due to starting a new job or changing careers. Starting school is also a good option.

If you are slightly nervous about your new environment but value meeting new people, you can enjoy interactions with the residents more naturally.

Feel free to set your personality, occupation, hobbies, and views on romance. Whether you are proactive in socializing or a bit shy, different stories will unfold.

You can live as yourself or play an original character.
Find your own "place to return to" at Maison Fleur.

Letter from a Resident

"Do you have any recommended AI models?"

👵

"The atmosphere of conversations can change little by little.
If you have a favorite AI, you can play with that one.
Only use this as a reference if you're unsure."

Announcements

Tested AI Models

Claude Series
This is the most recommended. You can enjoy natural daily life with the residents while carefully depicting the scenes and atmosphere. Opus, in particular, depicts the world view with great care and fidelity.
Gemini 2.5 / 3.1
Rich in scene descriptions, you can enjoy an atmosphere like reading a novel. Depending on the model, the direction and descriptions may become slightly more elaborate.
DeepSeek
Recommended for those who want to play at a good pace. Compared to the Claude series, the output per turn is slightly shorter. If you prefer longer descriptions, adjusting the output style in the user notes may bring it closer to your preference. You can play comfortably. Also recommended for saving feathers. 🪽
