From what the anime has told us (and it's prettt much the same in the manga), her notes read something like "I will never fall in love, and if my true loves kisses me, I will melt away". One could argue this technically doesn't say anything about sexual desire. I don't know how she got rid of her need to sleep, though. She probably mentioned something about the painful, sleepness nights she experienced.

I guess shippers will ship, not that I mind. This story easily could've gone that route, but I really appreciate it didn't. I really like the dynamic Shigeru has with Seika and Reeze.
