   Summary

   Kyomi saiki is well the only normal saiki sibling, maybe even simple minded.. but compared to her two brothers she has a whole generation more of social skills compared to both of them. She thinks kusuke is weird (he is) and Kusuo a little autistic. But she loves both of them anyways!
