(Touhou Crossover)
Pre-reading by Garlude Galaxia

When a portal storm, a cataclysmic cosmic event, the likes of which have never been recorded in any history, strikes the Eastern Seaboard of Equestria along with several other locations, many beings that do not belong end up inside Equestrian territory.

Marisa Kirisame is one of them. She's not very happy about it.

However, the Equestrian Government soon catch up to the witch, and offer her a choice - Spend an indefinite amount of time in a research cell, or to join a covert unit, known as the "13th Night Fighter Squadron," hunt down the other invaders, and earn her freedom.

So, with many questions swimming around her head, like "How is spoken Equestrian exactly the same as spoken Japanese?" and "Why is everything I know about biology wrong in this world?" Marisa must gain freedom and go home the only way she knows how: Shoot everything that moves.
