Just for you guys to know, this is not canon, this is just fanart and short manga of a giantess artist, it does have nothing to do with the real Puella Magi Magica Madoka. The personality will be quite the same but not the timeline or universe. I repeat, this is non-canon, the important things must be remind twice! To be exact, I didn't watch this anime or play the games, but I did read the wiki the part that this series is quite dark, dramatic and tragic.

Enjoy!
