Mairu Orihara



She kisses Aoba after Kururi does, claiming she was happy to get an indirect kiss from her sister.
 * Mairu is one of Izaya's younger sisters. She has a twin named Kururi. Like her brother, she's a troublemaker at school and introduces herself as liking to read encyclopedias, manga, and adult magazines. She also declares that she is bisexual and is looking for girls who are interested. This causes a stir in the class and she is bullied briefly until she responds to one of the bullies by threatening her with thumbtacks as well as taking her to the bathroom and stealing her bra. Later, the sisters are assumed to have framed the bullies for having drugs by sneaking them into their backpacks.

Along with her sister, she is known to be a big fan of Shizuo's brother Kasuka, stating that she would gladly see Izaya die in front of a truck for a chance to meet Kasuka.

Anime
There is a cameo of both of the twins walking side by side behind Simon and Walker. There is another cameo when Mikado checks the 'lost and found' notebook at the ending of episode 6 when both of the twins wrote down Kasuka, then drew chibis of themselves in the corner of the page.

Trivia
Both of the twins are bisexuals.
