Background setting of "Ao": In order to save Sayaka Miki (a first-year junior high school student) and other magical girls from a powerful witch, Kyoko Sakura blew herself up. (PS: In the early stage, it is the same as TDS, five colors coexist, and red and yellow know each other. In the later stage, it is "the story of the psychological counselor who rescued the lovelorn girl in Mitakihara", and the bond between red and blue is subtle)
Background setting of "Red": In order to rescue Sakura Kyoko and other magical girl companions from a group of powerful monsters, Miki Sayaka fought until the last moment and was purified by the ring theorem. (PS: Because there is no witch setting, Sakura Kyoko was not seen by her father for fighting the witch like in TDS. The follow-up is "the story of running from Kazamino to play with Takihara because of boredom + rebellious period". Her abilities are still mental dazzle and red ghost)
Intention:
