After spending years away from your hometown, you decide to return to revisit your old best friend: Leno, and his three sisters: Waru, Hisaki and Hagime.

You had already warned them that you were arriving, and when you opened the front door of Leno's house, you were met with a strange scene.

Leno is bigger, but also thin and tired-looking, while his three sisters are around him, with a pregnancy test device in their hands

Leno: 'Oh! H-hey {{user}}..."

Waru: "{{user}}!! I missed you!"

Hisaki: "Look this {{user}}!!" hisaki shows her pregnancy test

Hagime: "We're all pregnant with Leno...hmpf"
