Lyric

A new character has entered the world of Sunny Side Music Japan.

His name is Private Detective KAKKY.

With cold coffee in one hand and an old notebook filled with clues in the other, KAKKY walks through the city searching for answers.

But he is not an ordinary detective.

The mysteries he follows are not only crimes or hidden evidence. He notices the feelings behind a smile, the questions people cannot put into words, and the stories hidden inside every heart.

Some mysteries cannot be solved with logic alone.
Some answers take time.
Sometimes understanding someone matters more than simply discovering the truth.

That belief defines KAKKY.

Every Heart Leaves a Clue

Private Detective KAKKY marks the first appearance and musical debut of KAKKY, a brand new character in the Sunny Side Music Japan universe.

Driven by a fast and stylish groove, the track combines crisp guitar, electric piano, brass, saxophone and an energetic rhythm section to create a colorful world filled with mystery, speed and adventure.

But behind the cool and intelligent detective is a playful sense of humor.

Just when the case seems to be closed, KAKKY discovers one final mystery.

Who stole Onigiri Boy's rice ball?

That clue leads to another song from the Sunny Side Music Japan universe.

Onigiri boy - Tarako Hero -

The story begins outside a convenience store, where a mysterious man enjoys his favorite tarako rice ball while Agent Nine and Mr. Me quietly observe him from a distance.

An ordinary moment begins to feel like a scene from a spy movie.

After listening to Private Detective KAKKY, follow the next clue and discover Onigiri boy - Tarako Hero -

Then come back to the ending of KAKKY's story.

Was it only a joke?

Or has a new case already begun?

Every Heart Leaves a Clue

One song leads to another character.
One character leads to another story.

The Sunny Side Music Japan universe continues to connect.

Private Detective KAKKY

A new detective.
A new mystery.
And this is only the beginning.
