About This Game

but after being injured in an accident, your younger sisters decided to carry out a special plan.

That is—"to move to a safe deserted island and heal their older brother's body and mind!"

All the heroines are your biological younger sisters. On this deserted island, a new life full of affection and cuteness is about to begin.

Fishing, foraging, exploring, and cherishing heartwarming moments with your younger sisters……

In this game, while there are objectives, there are no time limits at all.

▲Al (Alhena Lumiere)

Three years younger than the protagonist, she is a cheerful, proactive younger sister who excels at household chores.

She loves taking care of her older brother and feels incredibly happy whenever she’s needed by him.

Deep down, she has a strong dependence on her older brother, but being considerate, she keeps it hidden so as not to trouble him.

Determined to stay by her older brother’s side forever together with Miu, she resolutely decided to move to this deserted island.

Miu (Miu Lumiere)

Five years younger than the protagonist, she is a clever little sister with a hint of mystery.

Due to her frail constitution and lack of stamina, she most enjoys staying by her older brother’s side to feel safe.

In order to stay by her older brother’s side together with Al, she planned and decided on this deserted island relocation project.
