Magical Girl Lyrical Witch

I am Madoka Kaname, a resident of Uminari City. I live with my family and friends. I am Kriemhild Gretchen, a monster that said no to being one and protect Uminari City to protect my family and friends. It would seem that my problems seem to relate to seeds judging by the latest upset to my life. Plus it seem that two puella magi have appear in my home, wait, why is one Nanoha?
