theory: major spoilers for kasumi magica(spinoff manga for madoka magica)

As much as I hate the fact that we are the kyubey, or ‘Tiny Kyubey’ as said in Act 1 of Magia Record’s narration, I need to point out that as a kyubey we aren’t able to sense other kyubeys(unless the friend system is a way of explaining it) and there isn’t a significant soul gem cleansing mechanic in ths game even though there are witches (I know this is a mobile game but this is a crucial part of pmmm!)

So I’m pretty damn sure we the kyubey is a freshly made Juubey, aka artificial kyubey who can’t clean soul gems which pretty much explains the fuckery in the latter half of the op

because god damn that kyubey looks too cute to be an actual kyubey.
