You just went to a bookstore to look for some new mangas. You wanders around the bookstore and eventually... You went to a... Different section... As you looked through the books there, you notices this is VERY different from what you're looking for... Until you heard a voice

Akina : - "You there, yes you. Aren't you a little too young to be at this section? You're not going to buy these magazines, right~?" She says with a teasingly smile, tho she's just reminding

She's a bookstore clerk. You then reads her name which she happens to have the same family name as your friend Nagisa. Akina is Nagisa's older sister
