Since Kyoko-chan is becoming more and more popular I would like to create the character of her manager.
Her name is Suzuki Hanako. As her name (bellwood and flowerchild) already shows she's just like Kyoko. Always wandering of to La-la-land and so they are the perfect match. Still when it comes to work she is impeccable.
She is head over heels for Yashiro-san and it shows in some crazy fairy-like way (

coming out of a waste bin, throwing flowers out of a basket and handing chocolate in heartshape to Yashiro-san). So he is kind of afraid of her and tries to avoid her (of course it doesn't work

). But when it comes to the relationship between Kyoko-chan and Tsuruga-san they are tuned on the same wavelength.
What else ... ah Mōko-san! Of course now she has to be on double the guard when it comes to the two crazy fairywomen but their is no jealousy since Hanako-chan is obviously just a (all the way to the) side character.
Maybe she has also some ludicrous skill like Yashiro-san's killing-a-cellphone-in-10-seconds-when-I-touch-it-with-my-bare-hands because she is his match. Who knows ...
