|Relatives||Yuuki Kasugano (Brother)|
Nana Kasugano (春日野ナナ Kasugano Nana) is the sister of the protagonist—Yuuki Kasugano and a heroine from Akiba's Trip 2. She is a girl very affectionate of her older brother and was about to start her first year in High School. She became a shut-in and has a huge liking for cat-based merchandise. Nana constantly calls her brother "bro-bro".
Clearly not one to take the initiative and interact with others, her quirky mannerisms and stilted, animation-and-game-inspired speech patterns make her difficult to talk to. She rarely comes out of her room nestled in the back of the Freedom Fighters' home base, to the point where others joke that she is something of a "secret character".
She had initially been referred to as Sister (妹), referring to her status as the sister of the protagonist from the second game.
- Hobbies: Tailoring costumes, being admired by her brother
- Special Ability: Gaming, sewing, modding various objects
- Likes: Carbonated drinks
- Dislikes: School
Yuuki's sister, who for some reason has decided to start living in MOGRA's back room. She calls her brother by a variety of cutesy names and is always trying her best to win some brotherly affection from him. Highly self-conscious and almost obsessively analytical, people tend to find her a little odd. She loves playing video games, tooling around online and making costumes for cosplay (though never, ever wearing them herself). She feels blessed just to be in Akihabara. Even though her brother is a Synthister, she doesn't mind. Brotagonist is Brotagonist, after all, no matter what his state of mortality (or normality) may be.
Nana has fair skin, blue eyes like her brother and lengthy black hair with a stubborn cowlick. She appears as an innocent school girl who wears a white bobble jacket, a black frilly-skirt and red shoes. Under her jacket she wears a pink top and she also carries a cat-shaped backpack, as well as a band aid on her right knee.
Despite being an innocent-looking girl, she has her quirks, recently becoming a shut-in from High School and skipping school to live the life in Akihabara's game centre MOGRA.
