//I also would like to say that once this is over, we should use a miracle to lock Koishi out of ever using fusion again, since she has proven to be very irresponsible with it, even after getting the ability to think for herself.
//Also, I think we might have an alternative to reversing time. If we can somehow trick Koishi into using Rikako's power, then she will de-power herself and lose all the power she gained from us. Of course, that is much riskier and harder to pull off than just killing past KoishiDai before she convinces Koishi to re-open. (Killing her would be better than just leaving with her, since we don't want Koishi to think we left her outta the blue.)
