A young alien sent to study on earth.
If his true identity is discovered he will be forced to leave earth. Because of this he will not use any alien technology even when being threatened.
Ari has short black hair and pale green eyes. Unusually, he has straight, horizontal pupils, though they are blurred slightly in his info-screen. He wears the default uniform.
He's a nonchalant-faced coward. He gets flustered quickly when touched, especially by anyone he likes a lot and is rather oblivious to certain things such as indirect kisses or gender specific clothes. He'll wear the girls' school uniform without hesitating to do so.
Zei was Ari's first friend when he arrived on earth. Ari cares very much for Zei, but is afraid to admit it to himself, as he's afraid that he'll have to leave her one day. Because of this, he unintentionally hurts her feelings sometimes and immedietly feels ashamed for doing so. He is slightly protective of her and often worries about her. Ari depends on her to teach him about things such as makeup and gender specific clothing.
He finds her to be adorable.
These two characters met when Zeitakuna dragged Ari to class 2-2 to see her big sister, Marena. She is quite intimidating in his opinion, and she has noticed his habit of occasionally checking how she acts around others. Ari depends on her to teach him how to cook or sew an article of clothing back together.
Ari has tried to touch her curl once, only for her to grab his wrist and "politely" tell him that it was a bad idea to even try. He has watched many a perverted student get slapped into the next wall because of that one gravity-defying lock of hair.
While he is intimidated by her, he finds her to be quite pretty.
