Rui Kamishiro

Rui is a tall boy who has thin, amber eyes with red eyeliner along the crease, and uneven, choppy purple hair with two cyan streaks. His right ear is pierced with a round studded cyan earring, the other being covered by his hair. His voice is gentle, though it becomes strained when he is excited or curious.

Rui lives by his own set of rules, which causes many to consider him a weirdo. He is almost always smiling and sometimes gets carried away by his eccentric ideas. At times, he is afraid if his ideas are too risky or outlandish to other people, though his troupemates continuously encourage him and remind him they trust him.[4][1]

Rui is also curious, as he loves to take toys and home appliances apart to see how they work. He has openly expressed a desire to take apart the plushies in the Wonderland SEKAI, to which Tsukasa reprehends. He is observant, and uses his observations to help direct his troupemates, encourage Mafuyu to understand how she truly feels,[2] and help Akito overcome his fear of dogs.[5]

He cares deeply for his friends, shown when he defended Emu and her dreams from her brothers,[6] as well as building NeneRobo to help Nene with her fear of talking to others. He is also a teasing and playful person, with an example being his constant ideas for performances that often involve putting Tsukasa's life in danger.

Fellow troupe member and friend. Rui now sees him as an actor worthy of a stage, and is confident in giving him very taxing (and occasionally dangerous) stage directions, knowing that he will proudly take the role. The two are known as the "Weirdo Wombo Combo" at school[9] (Also known as "Oddball 1-2 Finish" on the JP and KR servers), causing ruckus and trouble around the campus daily. Though, it's mainly Rui causing trouble and dragging Tsukasa into it.
