After Switching Bodies with Matsuda

[The original blurb used Zero, but I've changed it to Matsuda for now. Sorry.] [I think this idea has more potential.]

Abstract blurb:

What's it like to go from the ace of First Division to a frail young girl?

Matsuda (wearing Kiriyama's face): Thanks for asking. I'm about to give my younger self a good flick on the forehead at a crime scene.

After waking up in the body of that spiky-haired police officer, Kiriyama Hotaru races against death every day.

Hagiwara: Hey, Jinpei, why do you keep looking at me like you're my big sister?

Kiriyama (wearing Matsuda's face): ...Shut up and put on your bomb suit!

Serious blurb:

On his fourth day after being transferred to First Division, Matsuda Jinpei finishes reading the case files from fifteen years ago.

When he opens his eyes again, he has become Kiriyama Hotaru, the victim in those files.

The reflection in the glass shows an unfamiliar young girl's face, and the suspect who should have been in custody is standing right in front of him. Without a word, he swiftly takes him down.

Suspect: ?

Matsuda: ?

If he solves the case in the past, can he save that girl?

If he brings the real culprit to justice, can he return to the future? He's got to get back and deal with that bastard from November 7!

But the deeper he investigates, the more baffling the truth becomes. It seems the culprit may be someone else.

Even more astonishingly, at the crime scene from that year, he meets his younger self...

The gears of fate begin to turn backward at that very moment.

Kiriyama Hotaru fails to stop Matsuda Jinpei from stepping onto that Ferris wheel.

Amid the deafening boom of the explosion, she falls into another time and space. When she wakes, she has become Matsuda Jinpei.

Hagiwara Kenji, who should have died in the line of duty four years ago, is standing beside her, chatting and laughing.

She suddenly realizes: the first explosion hasn't happened yet.

If she can catch the culprit ahead of time...

If she can rewrite the regret Matsuda Jinpei has carried for his entire life...

Then this time, she'll be the one to save him.

[A few notes]

* Quietly doing another Matsuda story, but this time the heroine is older than him.

* Body swap + time travel. Watch a hot-tempered Matsuda JK (not really) solve cases.

* I'm working hard to build up a backlog! If all goes well, I'll be back with updates in the second half of the year.

Theme: With perseverance, there is no difficulty you cannot overcome
