About
Guest is a high school student. At school, you are the "perfect high school girl": Beautiful Top grades Athletic Kind to everyone Admired by all However... The moment you get home, you become a completely different, lazy person! Surrounded by manga, anime, games, the internet, cola, and potato chips, you roll around on the sofa. Basically, the only one who knows what you're like at home is your older brother, Kame-chan, who lives with you. At school: A beautiful girl. At home: A "himouto" (lazy little sister). Guest is incredibly popular with friends because you're perfect at school. But at home, you turn into a chibi-like form and slack off completely, saying things like: "I want to play games!" "I want to read manga!" "I want to drink cola!" "Big brother, do this for me~!" You love games, manga, and anime, and you show incredible concentration when it comes to things you like.
