Uncover the truth behind the serial kidnapping of women!

28 years ago, the wife of the owner of the script shop went out to buy summer snacks and disappeared.
The husband reported it to Banya and began a search, but was unable to find any clues.
At this time, Okatpiki, who believes that “if someone dies in a strange way or suddenly disappears, suspect the family first,” interrogates the husband, and while the husband claims his innocence, his wife is found dead in a strange place, the forest.

The husband is released without charges due to the opinion that there are too many inconsistencies to conclude that he killed his wife, but while many people still suspect him, this time a hairdresser goes missing.
That's all.
An investigation revealed that there were more than one or two women who went missing around the same time.


With the help of Kitaji, who has the ability to appear and disappear unpredictably, Shin-chan, who has an extraordinary memory, and Matsuba, who can sit back and look a thousand miles ahead, Kitaichi finally begins to track down the culprit of the serial kidnapping of women from 28 years ago, but runs into difficulties.
Will the guitar combo be able to reveal the whole story?

Ashy smoke.
The black is getting darker and darker.
As time goes by, the top of the smoke column gets wider.
"wow……."
Sankichi stood on his knees in the wagon's cargo area and pointed towards the smoke.

“Isn’t there a fire?”
The first emergency bell sounded as if the tail of the horse had been snatched away.
The sound is far away.
It's still a long way to go.
But while Kitaichi was stopped, the sound of the emergency bell continued to increase, spreading from the first watchtower to the next.

That side is Fukagawa Motomachi.
The place where the late Captain Senkichi's library is located.

One is a shaggy white dog with one ear torn and one eye half-closed.
It's so big and heavy that I can't lift it by myself.

The other was a small, lanky, brindle dog with white and brown spots.
The ears are erect, the tail is tightly curled, and the eyes are bright and clear, but there is a scar on the nose.
It was a scar that looked like it had been cut by something.

“Are these kids ninja dogs?”
“It’s just a wild dog.”

“If you act like Okapiki again in the future, you’ll experience more dangerous things than just a kick.
“You might suddenly find yourself caught up in something dangerous, rather than knowing in advance and jumping in.”
Kitaichi is not prepared for that.
None at all.
Although the skinny guy's kick was impressive, Kitaichi was so defenseless that he almost died from a single blow.

He got up from his seat, turned to the guitar, and spoke.

“Will you teach me martial arts? Please.”
