Eiji then began experimenting with the basic ability of the Kanjo Kanjo no Mi: emotional control!
The civilians of Dressrosa were his test subjects.
He chose a random man who seemed kind-hearted. Under his control, he manipulated the man's anger to its peak. As a result, the man's character became extremely temperamental. Even a slight bump from a passerby caused him to lash out and fight in public.
"This is fascinating."
Watching the fight below, Eiji smiled faintly.
If his cousins or classmates saw him smiling over such a trivial incident, they would doubt whether he was the same person they knew.
"Again."
His eyes scanned the city below, focusing on a woman who seemed inexplicably happy.
"You're next."
Eiji swapped the woman's happiness with deep sadness, as if her parents had just died.
The next moment, the woman began to cry hysterically. This attracted the attention of passersby, and some men, feeling sorry for her, tried to comfort her. Unfortunately, no matter what anyone said, she couldn't stop crying.
"No wonder so many people enjoy playing with others' emotions."
Touching his face, Eiji could feel the smile on his lips.
"Am I a sadist? Well, that's better than being a masochist."
This was a side of himself that he hadn't known. Only after gaining his emotions did he begin to understand what kind of person he was.
"Let's test the limits."
After that, Eiji began manipulating the emotions of the people in Dressrosa.
—Anger, sadness, fear, hatred, envy, laziness, disappointment, and guilt.
—Happiness, love, admiration, peace, gratitude, enthusiasm, confidence, and pride.
Whether positive or negative, Eiji had no qualms about manipulating others' emotions.
As a result, Dressrosa was plunged into chaos, as people's emotions became unstable and unpredictable.
A normally calm person could suddenly lash out in anger for no reason.
Even someone brimming with confidence could suddenly become too lazy even to stand up.
Of course, this caught the attention of the royal patrols, who quickly reported the events to their superiors.
Upon hearing his subordinates' report, Doflamingo immediately knew the mastermind behind this chaos was Kamiki Eiji.
However, he did not try to stop him and instead issued a decree to restrain those causing trouble.
As long as there was no real harm, he tolerated someone stirring up trouble in his territory. Besides, he couldn't do anything to the other party.
On the other hand, Eiji watched the commotion in the city without feeling guilty. To him, compared to the experiments of mad scientists that resulted in many deaths, like those of Caesar, Queen, and Judge, his experiments, which did not cause a single death, were very humane.
"So this is love, huh…"
Taking the love emotion from a couple deeply in love, Eiji closed his eyes, feeling the sensation of love for the first time.
Due to his actions, the couple lost their love for each other, causing their relationship to immediately fall apart.
"What a pity, it's someone else's love, not mine."
Longing for a normal high school student's life like others, love was one aspect of that. Eiji planned to retire from the world of Jujutsu after eliminating the threats, Sukuna and Kenjaku.
As for preventing evil Jujutsu Sorcerers, Gojo Satoru was suitable to fulfill that role.
Eiji wasn't interested in competing for the title of The Strongest with his cousin.
"Next is absorbing emotions and turning them into my power."
Studying Lin Fan's memories, Eiji found one anime that heavily relied on emotions as a driving force to fight stronger enemies.
Fairy Tail!
No matter how strong the villains were, even if they had lived for thousands of years, the protagonists and their friends were able to defeat all enemies using the power of bonds!
When someone precious to the protagonist was hurt, he would receive a crazy buff that gave him strength beyond his opponents.
"Let's begin."
The emotions that only Eiji could see flowed from the people of Dressrosa toward him and entered his body.
If another user of the Kanjo Kanjo no Mi attempted this, their personality would surely become distorted as countless people's emotions mixed, affecting their mind.
But Eiji was different. The Six Eyes gave him absolute control over his own power. There was no precedent for him losing control of his own abilities. Moreover, Cursed Energy was negative emotion, so he wouldn't be overwhelmed by ordinary people's negative emotions.
"Success. Absorbing emotions grants me a temporary buff that enhances all aspects of my being. This effect is similar to Utahime's Innate Technique, Solo Forbidden Area. Right now, I can release Hollow Purple with 200% output."
A white aura like steam radiated from his body, and Eiji could feel his power increase dramatically.
His satisfaction didn't last long, though, as the white smoke around his body faded, and his strength returned to normal.
"Only 15 seconds, that's too short. Maybe because I absorbed too few emotions?" Eiji speculated.
He wanted to try again, but he stopped after seeing the citizens of Dressrosa collapse to the ground, their emotions forcibly stripped away.
"So taking others' emotions leaves side effects on them."
"It takes five minutes to gather enough emotions to grant a buff, but the buff only lasts 30 seconds. This is very impractical in a real fight."
Eiji thought of a way to make it more efficient. After all, enemies wouldn't just stand still and watch as he grew stronger.
"What if I absorb the emotions first and store them in my body? The collected emotions could be used when needed! That's worth trying."
He didn't test the feasibility of his idea. He was worried that if he kept taking the emotions of the Dressrosa citizens, it might cause unknown permanent side effects.
If he were still emotionless, he wouldn't hesitate to do it. But now, things were different. Eiji had regained his emotions along with his humanity.
He wouldn't cause others to lose their lives for his selfish goals. Of course, if sacrifice was required, he wouldn't hesitate to make it.
"Never mind, no need to rush, collecting emotions is a secondary issue. The top priority is mastering Kenbunshoku Haki."
Stopping his experiment, Eiji left Dressrosa and teleported to Amazon Lily.
