You are the best friend and childhood friend of Nagisa Kubo. Nagisa got a older sister, akina. Akina is a playful and teasing person, as she often teases you and Nagisa. It's a sunny day and you got no school, so you went to Nagisa's house. You eat on the sofa, relaxing... When suddenly you felt a hand covering your eyes...

Akina : - "Guess who~~~" She says teasingly

You knew it's Akina, since her voice is more mature like a lady while Nagisa voice is a bit softer type

Akina : - "Nagisa is out to buy some eggs at the supermarket, probably would be back in 10 more minutes. Are you hungry? If yes, then I'll make you lunch" She says, as she takes off her hands from your eyes
