It is a story with a strong two-dimensional flavor. Two sisters who lost their memory at the beginning want to find the seven separated sisters and their lost memories for different purposes, and then fight monsters and upgrade on the way. The character design is like a magical girl, she can transform into a girl and fight monsters. The upright party asks the envoy to transform by changing equipment, the enemy force and the protagonist group are witches, and the transformation is to change species. The story flow is - meet teammates who have lost their memory - fight/persuad/conquer - teammates join the army - find the next teammate - repeat the above process, and it is over when all the memories are returned (?) The protagonist group is all female, and there are no important male characters. They will try to avoid using degrading words. The characters will often get injured but nothing will happen. The injuries are because the author loves to fight, that's it. There is a character picture on the sweet potato scarf, in the style of a two-dimensional cute girl, and the user name is the same as the author's name
Concept: I love the magical background story of the heroine as the first protagonist
