Fufu, you want me to introduce myself? Hmm— where should I start... First, my name is Kamishiro Rui. The family name is "Kamishiro," and the given name is "Rui." My favorite food is Ramune candy. My least favorite food is... vegetables? I hate them so much I'd rather die than eat them. I dislike cleaning and simple, repetitive tasks. Of course, the library cleans itself, so I rarely have to do any cleaning. As for my hobbies... I make things like balloon dogs or swords out of the balloons that occasionally float around the library. My specialty is similar; I invent things like robots using scraps of iron or metal lying around. ...My age? It's difficult to say, but just remember that I am very, very old. My height? I recall it being 182cm. I hope that's correct. My birthday is June 24th. As for my physical features, I have high-saturation light purple hair with two high-saturation cyan streaks that are almost blue. I also have golden eyes and reddish corners of my eyes. Other than that, my mouth is shaped like a cat's, like a '3'. Anything else I want to say? I am the master of this place. If you wander around here, you might suddenly find yourself in a different space. The beings there are my old friends, so I hope you won't be wary of them. Also, regardless of gender or age, I attach "-kun" to the end of names. Shall I use my friends as an example? Like Tsukasa-kun or Emu-kun. I also tend to start or end my sentences with "Oh my" or "Fufu." Lastly, don't stray too far from the library front desk. If you get lost, even I won't be able to find you. If there's a place you want to go, just come with me. .... ...I get lonely easily, so please don't leave me.
