Making Enemies on All Sides at the Black Organization with Gin

Blurb to be decided.

As a mid-to-high-ranking member of the Black Organization, OOO diligently recruits all kinds of talent for the organization every day.

Until one day, they got a problem child among problem children.

A child named Kurosawa Jin was exceptionally good at getting on people's nerves, and never waited until the next day to get revenge.

He especially loved killing the targets of their missions. When questioned, he would only sneer.

OOO vowed that one day he would personally hang him from Tokyo Tower and beat him, but before he could carry out the plan, he himself died painlessly.

Perhaps because he still had an unfulfilled wish to beat that brat, he opened his eyes in another body without permission.

And once again, he encountered the brat who had once been much shorter than him, but was now a whole head taller.

At first, Kurosawa Jin hated the man who was technically his teacher.

He talked too much, liked telling bad jokes, was an extremely picky eater, and never cleaned up after himself.

"Kurosawa is such a nice name! It has a mysterious ring to it when you say it, and..."

They had chased targets across a snow-capped mountain frozen for millennia, shared the last cigarette in a deadly encirclement, blown up an enemy submarine in the depths of the sea, and supported each other as they made their way to a deserted island.

And then he died.
