Quick Transmigration Roleplay by the Police Academy Group

Before reading, please enjoy the masterpieces BV1TT411z71T and BV1dN411A7Fv.

Bound to the System, the police academy group has no choice but to embark on a one-way journey across different universes to save the world. They let loose and put on one wild performance after another, while also being forced to wreck their vocal cords. Don't ask why. The System turns out to be a niche music-saves-the-world System. If the five want abilities and identities suited to life in each world, they must perform together flawlessly and sing the assigned songs as a group!

Matsuda Jinpei and Furuya Rei, both severely tone-deaf, feel as if they've entered a torturous hell. While waiting outside the recording studio, they are always on tenterhooks, and in the end, only their childhood friends' coaxing gets them to enter the recording booth, reluctantly.

Hagiwara Kenji, Date Wataru, and Morofushi Hiromitsu smoothly finish their solo sections, happily enjoy the two tone-deaf singers' futile last-ditch efforts, and then send them into the depths of song without a shred of brotherly affection.

After watching the two finally get the hang of it after countless takes, they stop laughing at them and start familiarizing themselves with their upcoming lines in the waiting room.

When it comes to the five-person chorus, the three exchange knowing smiles and return to Matsuda Jinpei and Furuya Rei's side.

Then their powerful chorus rings out along with the accompaniment, five police cadets singing loudly enough to shatter the glass partition.

(The glass, nearly shattered: Your voices resonate so well when you hit the same notes. You guys are so high and mighty. (Not))

World One: They play the five most famous SSS-class colonels on Blue Star in the galaxy, forever victorious in battle against alien invaders and respected and feared by all humankind! (In progress)

World Two: In a modern age where everyone is connected to their destined partner by a red string, they play the hottest boy band and resolve the public-relations mess caused by fans getting tangled up with one another! (Incomplete)

World Three: They play five senior officers in black-clad special police forces who seem to despise one another but are actually incredibly close. In a world controlled by corrupt, rotten forces, they bring the people a ray of original light. (Incomplete)

World Four: They become merfolk, break through the layers of cages set up by humanity, seize the last glimmer of hope for their people's survival, and warn and punish some of the greedy humans! (Incomplete)

World Five: ...

Then, at the very moment they are about to leave, the System gives Furuya Rei a special mission in front of the other four: have your friends sing your final song, "Time-Stop Illusion."

Why does it suddenly feel so sad to sing this song, which he has repeated in his heart countless times, all the way through?

Why are you crying?

Watching the four listen to him in silence, Furuya Rei doesn't realize that his own eyes have grown misty too.

When the song ends, they smile at Furuya Rei and say, "Come on over." "Rei." "Let's go home."

He smiles. "Okay."

Theme: The police academy group sound just like themselves when they sing, and they sound so good!
