The original intention was to be a female supporter, Gojo Satoru, but Anna is just too cute. The heroine is Anna, who appears in Chapter 7 of FGO. FGO is just a background board and is basically not written about.
Probably the height difference among the tattoos of female vote-getter Gojo Satoru is the biggest.
It's a love story between 134 legal lolita and 190 male high school students.
Probably a story of love and hope.
Intention: It's written blindly, women don't need this kind of thing
