The Ordinary Teitan High School Student's Daily Life as a Spirit Warden

(I)

During spring break in the year before she starts high school, Jiang Yu becomes the Saniwa of a corrupted Honmaru.

When she first arrives, the sword warriors are all very "friendly."

* * *

On the first day, Jiang Yu is practicing with a sword in the training ground. Seeing this, Kashuu Kiyomitsu and Yamato no Kami Yasusada assume she's just putting on a show.

Yasusada: "Do you think she'd agree to spar with me if I asked?"

Kiyomitsu: "No idea. Don't care."

The next second, Jiang Yu chops through a thick wooden post with a wooden sword.

Yasusada, who was about to step forward: "...You're amazing."

"Am I? Kyogoku from the martial arts school next door can kick a stone pillar in half. I've still got a long way to go!"

It's her first day of school, and she's about to be late, but Tsurumaru, her school companion, has such low mobility that he can't keep up.

Jiang Yu: "How about you turn back into your sword and let me carry you?"

Tsurumaru's gaze slowly turns dangerous. "Do you know what it means to ask a sword warrior to turn back into his true form?"

"If you don't like that, let's do it another way."

That day, a Tsurumaru Kuninaga in a high school uniform is seen being carried bridal-style down a street in the district by a Saniwa whose speed rivals that of a tanto...

Later, the Time Retrograde Army plans to work with the Black Organization to disrupt the order of the Conan universe.

Jiang Yu finds Mikazuki. "Mikazuki, you've served as my attendant for a long time, and I trust your abilities more than anyone. We need someone to infiltrate the Black Organization..."

"If you need me, my lord, I would be glad to do it."

A few days later, Mikazuki runs his hand over his completely transformed true-form sword and regrets his words. "My lord, what is this?"

"A sniper rifle!" Jiang Yu flashes a thumbs-up and a big, toothy grin.

"Grandpa, times have changed!"

(II)

Conan notices that a lot of dangerous people have recently shown up in Beika Town.

First, there's his fellow Junior Detective League member, Tora Todo of the Awataguchi school. The boy seems timid, but when faced with thugs, he grabs a sword and thrusts straight at their vital spots. Conan barely manages to save the thugs.

Then there's Nagayoshi Osafune, a suspect in one of his cases. He carries a sword and claims to be an exorcist. The murderous intent he occasionally lets slip is highly suspicious, but he isn't the culprit in that case.

Finally, a new host club has opened on a street corner. The hosts use sword names as their stage names. Each one is strikingly handsome in his own way, and every one of them has a murderous air about him. They're all skilled swordsmen!

Conan decides to investigate.

In the end, he traces them back to his high school classmate Shirakawa Chisato, a fellow kendo expert who once saw him turn into a child.

"Shirakawa, is there something you'd like to tell me?"

Shirakawa Chisato, code name Jiang Yu, is actually the master of all the sword warriors mingling among humans mentioned above.

"Hahaha, what are you talking about? I have no idea what you mean. I'm just an ordinary high school student."

A crossover of Touken Ranbu, Demon Slayer, Detective Conan, and Natsume's Book of Friends, with a few lighthearted everyday-life anime mixed in, like Monthly Girls' Nozaki-kun and Ouran High School Host Club.
