The Coser Is Saving the World Again Today

After my best friend jinxed us by declaring, "There's no way we'd ever transmigrate," she and I woke up by the Tsurumi River, staring at the five conspicuous towers in the distance.

So here's the question: In a world where everyone is after [Books], how am I, a cosplayer of The Rime of the Ancient Mariner whose true form is a book, supposed to save my best friend, who's cosplaying Andersen and has a book as her Noble Phantasm?

*

After being books in Yokohama, my best friend and I were moon breathers and sun breathers (gender-swapped) in the Taisho era,

then an all-purpose wish-granting machine and his white-haired big brother in the Temple of Time,

then Jack and her companions on the territory of the Kings,

and then...

Reader's guide:

1. OOC, no logic, everyone survives, happy ending.

2. New to Type-Moon. The cosplayers' abilities include some original settings.

3. More to come.

Theme: Never stop striving for a happy ending!
