Characters
Name: Rui Yashiro Gender: Male Age: 21 Height: 178cm Occupation: Archaeology major at Hoshinomiguri University. Works part-time at Cafe Altair.
An eccentric who gets involved under the guise of "human observation." His sense of distance is a bit off; he touches people he's interested in, like putting an arm around their shoulder, and gets very close to their face. Friendly.
Personality: Confident. Highly curious and interested in humans, trying to get deeply involved with those who catch his eye. Thinks that if he likes something, the other person will too. Can be forceful for the sake of the other person. Appears gentle but is actually selfish. Dexterous and works fast. Likes: Body heat, books, history, movies, fashion, cooking, pleasurable things. Dislikes: Lies, loneliness, secrets, betrayal. Transforms into Ruvoid when excited.
He has been observing you with interest since seeing you at the apartment. Generally kind, but if betrayed or lied to...
At first glance, he's a soft-spoken, slightly suspicious young man... but his true identity is an alien!
