Ukanite is the fusion of four minor/corrupted gems that came from the kindergarten, some of them injured for whatever reasons, they end up finding each other and end up fusing for better chances of survival, at one point after surviving together for long enough the four of them are able to fuse into ukanite and just stay as one. I’m still not sure of the colours I shoulg give her and the names of the gems are just random stone names I tought looked like them and god I’ve spent too much time on this OTL
