[Touken Ranbu] A Certain Scientific Master

[This is a prequel to A Certain Scientific Eternal Kihara. You can skip it if you like.]

While fighting the Time-Traveling Army, the Honmaru lost their Saniwa, and eventually, for reasons unknown, ended up in a strange world...

The sword warriors of this Honmaru, with no Saniwa, spent every day plotting how to ensnare a cute little thing into becoming their Saniwa so they could leave this desolate yet perpetually turbulent world called the Paranormal.

The sword warriors: We want a Saniwa!

The future Saniwa: Tch, after spending so long in the "New World," some interesting characters have finally shown up... Huh, I've been making a mess of the "New World" for ages. It's about time I "went out."

...Who knows how much time passed. After the Saniwa took up the post, Kitsunezuka felt like his hair was falling out every day.

The Honmaru's Kitsunezuka: Why does my Saniwa spend every day thinking up ways to stir up trouble without getting caught?

This story is also known as My Saniwa Plots Trouble Every Day and On the Road to Protecting History, Someone Always Comes Along to Make a Mess.

The early part is probably silly everyday life, and the later part is silly battles???

This came from an idea I had after playing the Touken Ranbu mobile game. There may be elements from A Certain Scientific Railgun, and the main crossover is Touken Ranbu, though there might be other anime too. The secondary crossover is A Certain Magical Index.
