>>86957671She's human biboo / not affected by ascended's influence
The power to make pebbles from golems come from ascended (basically meaning pebbles are evil people until they get purified by biboo), until things go to shit and Ascended is separated from GEOW. GEOW goes and teaches that power to schoolgirl biboo.
Ascended is from the future but she exists in the same universe because she can hop timelines
Having a stable amount of pebbles gives her the pink "juice" that is basically magical girl fuel, and probably affects her in some way. its implied that current biboo (this universe) is pre-ascended biboo
