Beach Vacation (Kamen Rider Ghost, Agender Ganma universe)

This will be added to the Agender Ganma post shortly, but it's split out as it fills a square on my GYWO bingo (which I need to paste to here), for beach with palm trees, featuring Chiyo, Gako, Haru, and Comede.

It's set after my Unconventional Courtship fic "A Dance We Do" and references it.
( And probably is quite an infodump.... )
