+a no Tachiichi summary:
Satoki Houma is an imaginative girl who enjoys shoujo manga. She has long comes to terms with the fact she will never be the type of girl that is the heroine of a manga — purely because she isn’t pretty, and she has decided she prefers to watch events unfold rather that get involved in any case. However, in the perfect shoujo manga twist, one day she gets dragged to an alternate world where the people have summoned a Holy Maiden to save them…!
Except so did her classmate, Haruka Toudou, who fits the exact model of a Shoujo Protagonist. Naturally, Satoki is overlooked for Haruka… except it’s not Haruka who has the powers of the Holy Maiden they wished for. What will Satoki do!?
