I'm Madoka. I'm Really Sorry

I wondered why I was standing here. Oh, that's right! I traveled through time! I traveled to the world of the magical girl Puella Magi! But wait, this plot line seems off! How did I become Puella Magi!? And a magical girl?! But if I'm a magical girl? Then what is this Salvation Witch's Lament Seed in my hand? ...Oh, so there's a real Puella Magi! ! But wait, aren't there too many Puella Magi? Why do I feel like all of these Puella Magi have a bit of a sister complex?! And me! No! Yes! A sister!!!...Wait a minute... "That... Flame Demon, I'm really not Puella Magi!" "Wait... You... Don't come over here!!"
