As a first-grade elementary school student, he recognizes calculus symbols and can even write advanced mathematical formulas.

But he couldn't solve a single calculus problem.

The pain and struggle of having your mind filled with things you don't even understand yourself is something that only those who have experienced it can truly comprehend.

What's worse is his temperament.

The worldly wisdom, power struggles, and scheming of Karasuma Renya over the past 130 years are meaningless to a child.

He did not become kinder, but rather more violent.

He doesn't know how to weigh the pros and cons, assess the situation, observe the changes, or play the long game.

Instead, they make the most extreme decisions based solely on momentary likes or dislikes.

It was in this chaotic and dangerous state that he barely managed to figure himself out, which can be considered a failure.

He immediately ordered the elimination of the Miyano couple.

But he immediately regretted it after that, because no one went on to research the antidote for the second-generation drug.

No one is researching drugs that can be successfully developed anymore.

Karasuma Renya was screaming hysterically in the room, and nearly ordered the killing of all the organization members, creating a tragedy even more horrific than 30 years ago.

Vermouth and Gin, who were standing next to him, realized something was wrong and forcibly stopped him.

After discovering that he was incapable of making rational decisions, they simply removed him from the organization's permanent headquarters and relocated him to a remote place.

Anyway, the organization's boss has always been mysterious, and his refusal to show himself in public has not aroused any suspicion.

When it comes to organizational developments or actions, Vermouth and Gin can only discuss and make decisions with Rum, and then symbolically report to the boss.

He had to appease the boss, keep Rum in the dark, and continue building the organization while recruiting new researchers to patch things up.

Absinthe and Gin had a truly bitter past.

The only hope was Shirley Miyano, the potions prodigy who had been studying in the United States for four years and was about to be admitted to Cornell University.

Fortunately, a few years later, when Karasuma Renya turned 12 again, things seemed to be turning around.

Karasuma Renya was precocious, and with the knowledge and experience he had accumulated over a lifetime, he quickly passed through his ignorant childhood.

At 12 years old, he was already able to handle things with more maturity than a 20-year-old.

Of course, it can only be compared to 20-year-olds.

His volatile teenage years made him resentful of Vermouth and Gin, who were always interfering in his lives, so he simply sent them both to the United States.

The United States was a very suitable environment for the growth of such organizations, and the distillery's overseas influence grew rapidly at that time.

Meanwhile, Karasuma Renya was engaged in a battle of wits with Rum, the second-in-command he had personally chosen, on his home turf, trying to prevent Rum from completely sidelining him.

Karasuma Renya knew that the organization members would not accept a 12-year-old boss, and that he could not show himself for the time being.

We can only wait.

We're waiting for Shirley to return home after completing her studies and discover the real elixir of immortality.

He planned to appear in his prime and take down Rum, who harbored ulterior motives, and all the undercover agents within the organization.

Wait until... grow up...

However, it seems now... we can't wait any longer.
