Ayha and Class S agent Saulo Lima were on a mission. Their target: an Inumano known as Ioká, a Class B Isang user whose power—nicknamed Reactive Factor—manifested through a yo-yo, his Anchora. His Limiar prevented him from attacking children, the elderly, or vulnerable people. A cruelly specific ethical boundary for someone who had already murdered two senators under investigation for money laundering and a real estate tycoon. Now, it was up to Argon to bring him to justice.

The SEA (Advanced Espionage System) had provided the coordinates. They were downtown in São Paulo, following the trail Ioká had left behind.

Meanwhile...

On the sixth floor of a business building, Judge Carlos Musguitel stared out the window of his private office. The city felt distant, indifferent to his choices. For months, he'd been under investigation for accepting bribes to reduce the sentence of a state deputy. The price? Two hundred thousand reais. Dirty money. Easy money. Money that now weighed heavily.

He wondered where it had all gone wrong. The beach house loan? The mounting interest? Or maybe when that bald deputy offered the cash with a disgusting smile?

A sound behind him. Footsteps.

Musguitel turned slowly. A thin, tall man with cold features and a firm gaze stepped from the shadows. Sharp nose, short hair, beige shirt, black pants, holding a white yo-yo.

"Beautiful city, isn't it?" the man said. "Who are you?" asked the judge.

"I'm the justice you tried to sell."

He grabbed Musguitel by the neck, lifting him off the ground. "The same justice you claimed to represent. But really... you betrayed it. For a beach house. For a dirty check."

The judge tried to speak, but it was too late. "You're a disgrace to this country," said the man before driving his hand into the judge's stomach. Blood splattered. Musguitel fell to his knees, coughing, eyes wide with fear and disbelief.

The man manipulated the yo-yo. With surgical precision, he launched it in a controlled rhythm, like conducting an invisible dance. "In toc," he murmured.

A colossal version of the yo-yo burst from the floor and smashed into the judge, sending his body flying out the sixth-floor window.

Musguitel didn’t scream—not from lack of pain, but from resignation. As he plummeted, he thought: if two hundred thousand reais cost me my life, then the billions others have stolen will be paid for too. A new era had begun.

Street Confrontation

The body crashed to the pavement just as Aysha and Saulo were patrolling the area. Saulo approached, examined the remains, then looked up.

"Look who decided to show up." "Who?" Aysha followed his gaze. There he was. Ioká. The yo-yo man.

"If we’d gotten here sooner..." "There was no way to know," Saulo replied, serious. "Now he has four deaths on his record. Time to take him in."

Ioká grinned from above. He threw the yo-yo, anchoring it to a first-floor window. He leaped and landed with flair—knee and fist to the ground, like a scene from a cheesy superhero movie.

"I knew they'd send a Class S agent. I bet they upgraded me to Class S too, huh?" "Still B-class," Saulo replied. "And we didn’t know you were here. Just lucky."

"Yeah... 'lucky.'" Ioká eyed Aysha. "And her? Your sidekick?" "My name is Aysha," she said, drawing her sword.

"Wow, so intimidating," he mocked. "Argon runs a daycare now?" "She’s my student," Saulo replied. "And you’re about to get schooled."

"Then let the class begin!" Ioká shouted, launching his attack.

He performed a combo with the yo-yo: two forward swings, one to the side, then a quick pull. The string turned into an energy blade.

Saulo didn’t flinch. He manipulated his magic cube, clicked two yellow squares. "Wall!"

Two massive walls materialized and crushed Ioká before he got close.

Aysha watched, impressed. But then, the cracking sounds. The walls exploded into shards. Saulo shielded Aysha with his arm.

Ioká emerged from the wreckage, laughing. "Not bad, old man."

He transformed the yo-yo again: left, right, palm extended. "Blade!"

Energy blades flew at Saulo. The agent placed two green squares. "Column!"

A steel column rose from the ground, blocking the blades with a loud clang.

"Impressive," Aysha murmured, as if watching a live combat lesson.

Ioká didn’t back off. He turned the yo-yo into a shock glove and charged into melee. One punch. Steel shattered. Another. Saulo dodged. Another. Missed. "You can’t dodge forever!" Ioká yelled.

"And you talk too much," Saulo replied.

Three blue squares. "Crater!"

The ground vanished beneath Ioká. An endless abyss swallowed him. His scream echoed into nothing.

"Took me a while. I was assessing your level," Saulo said. "Confirmed. Still B-class."

"Whoa! That was amazing! Now what?" Aysha asked.

"Now we wait for Operations. They have the right traps for him. I already sent the alert."

Ten Argon agents arrived swiftly. The leader approached Saulo. "Another one for the vault?"

"Fresh delivery. Still falling," Saulo replied.

The leader grinned. One agent activated their Isang. Chains of energy launched in an X shape, forming a sphere that pulled Ioká from the abyss.

"This isn’t over, Saulo!" Ioká shouted from inside. "Isang! ISANG!! What the f#ck?! It's not working?!"

"Nothing works in there, dumbass," the commander replied. "Take the little menace."

Five agents grabbed the sphere with containment chains. "I'll escape this bubble! It doesn't end here!" Ioká yelled.

Aysha watched, fascinated. Argon's structure was surreal—even someone as destructive as Ioká could be neutralized with military precision.

The leader nodded at Saulo. "Thanks for the assist, professor."

"Operations is always welcome," Saulo replied politely.

Argon's vehicles rolled out, transporting Ioká like another trophy of urban warfare. Around them, some bystanders watched the end of the brief battle, scared but relieved. No one but the judge was hurt. A successful mission, by Argon's standards.

"I don't know about you, but I’m starving," Saulo said. "Best idea today!" Aysha replied. "The best restaurant in the city is nearby. Let’s go!"

Saulo laughed loudly. "You went straight from training to a mission and saw all this... yeah, you earned a good meal."

"You did all the work, I just watched!"

"Today, yes. But your day will come, Aysha. Soon, you'll be on the front lines. For now, let’s eat."

"Yesss! Let’s go!" she shouted, already running toward the restaurant.
