I... had a character idea a few days ago, but I've not posted to apply or anything mostly because of the somewhat... awkward way things would need to happen to make it work? The simple version is that to take the character from the right point as-is would introduce a temporal problem due to coming from somewhat earlier in the series as compared to another character. But given something else that happened, it's entirely possible to explain around it.

Or in less obtuse terms: Kohinata Miku with the Shenshou Jing (but without the huge-ass laser due to lack of synchronisation), theoretically because if you gathered a bunch of shit from the moon after G and then got someone who could repair and enhance relics, you'd probably end up with that. And who else would you give it to? xD
