This Unscientific World [Crossover]

I, Matsuda Miyo, an ordinary girl who has believed in science all her life, had just barely survived the challenges to my worldview posed by interdimensional tennis and magical basketball. Then, just before graduating high school, fate dealt me its final blow

All because of the little fox that suddenly appeared in my room and could talk.

To make ends meet, I became a Saniwa capable of awakening the spirits of swords, and embarked on a path that nearly split my personality in two.

I feel like a real-life Sailor Moon. By day, I follow my mentor and research all kinds of cases. By night, I transform into a warrior who saves the world, roaming the rifts in time and space with a group of supernatural beings.

Until I met the most important variable in my life.

I gave my precious first love to a bottle of bootleg liquor from a distillery, and that bottle kept me drinking for the rest of my life.
