Marvel's master of cosmic magic-Chapter 602

"That aura... so it really is you."

The instant Rowan Mercer sensed that familiar, abyssal presence, he stopped guessing and vanished. Space folded, and he reappeared directly above the ruined Magic Council headquarters.

The scene below confirmed everything.

High in the sky, the Fire Dragon King had fully manifested from within Natsu, locked in combat with the Black Dragon. The clash was brutal, but one-sided. Even in his true form, the Fire Dragon King was being pushed back.

Below them, Natsu and the others were fighting desperately against nine demons, their formation barely holding.

Rowan stroked his whiskers thoughtfully.

"Perfect timing," he murmured. "Once I deal with the Black Dragon, these demons can be wrapped up and handed over to Mirajane. Her Take Over magic could use some new material."

He stopped suppressing himself.

For the first time in this world, Rowan released his full presence.

The change was immediate.

Magic surged outward like a tidal wave. The sky darkened as thunder rolled in from nowhere. Black clouds swallowed the sun, winds tore across the ruined city, and lightning split the air again and again. It looked less like a battle zone and more like the opening moments of an apocalypse.

Every fight on the battlefield stopped.

Fairy Tail’s mages retreated instinctively. The demons of Tartaros pulled back in alarm. Even the Black Dragon paused, its massive form shrinking as it assumed a human shape, eyes narrowing as it focused on the source of that pressure.

"Master! It’s the master!" Fairy Tail cried out.

Relief spread through their ranks instantly. To them, Rowan’s arrival meant one thing.

The battle was already over.

Across the field, Mard Geer stood frozen. The magic rolling off Rowan crushed his confidence completely. He had known Fairy Tail’s guild master was powerful. He had even believed he could surpass him.

Now, the truth stood before him like a mountain before an ant.

"Run," he thought desperately.

He turned and fled without hesitation. The other demons reacted a heartbeat later, scattering in the same direction. Their curses meant nothing in the face of such overwhelming disparity.

"This is impossible," Mard Geer’s mind screamed. "Even E.N.D... even Zeref shouldn’t be this strong!"

"Stop."

Rowan’s voice was calm. 𝓯𝙧𝙚𝒆𝙬𝙚𝒃𝙣𝙤𝒗𝓮𝓵.𝙘𝙤𝙢

Time itself obeyed.

The entire city froze. Wind, lightning, debris in midair, even the fleeing demons were locked in place, unable to move or breathe.

"Seal."

Rowan flicked a card from his paw.

A radiant sealing array unfolded in the air, swallowing the nine immobilized demons one after another. In seconds, they were gone, imprisoned within the card as if they had never existed.

The spell was Rowan’s own creation, a hybrid born from multiple worlds’ sealing systems. Once a target was restrained even briefly, escape became nearly impossible unless the victim possessed comparable mastery over sealing arts.

These demons never stood a chance.

"So it is you," the Black Dragon said slowly, studying Rowan. "I’ve seen you before... somewhere."

Time magic didn’t affect him, but Rowan’s raw presence did. Uncomfortably so. Even the Black Dragon’s vast reserves felt thin by comparison.

Rowan released the time lock and turned to face him, smiling faintly.

"We met in the northern lands," Rowan said. "Back then, I wasn’t worth remembering."

He remembered it clearly. Watching Gildarts fight this monster. Watching a single casual blow cost Gildarts a limb. At the time, Rowan had known better than to interfere.

That was then.

"I don’t care," the Black Dragon replied coldly. "I’m here to kill dragons and Dragon Slayers. Stay out of my way, and I won’t bother killing you."

Rowan chuckled.

"Unfortunately for you," he said, raising a paw and pointing straight at the dragon, "I came here for you. So yes. I will interfere."

The Black Dragon’s eyes burned with rage.

"Then I’ll kill you first," he roared, transforming back into his true form. "Then I’ll erase everything else. This world will end in ruin!"

He opened his jaws wide.

"Black Dragon’s Roar!"

A beam of pure annihilation erupted forth, far more powerful than anything he had unleashed before. The energy distorted space itself. Had it struck the ground, entire regions of the continent would have vanished.

Rowan didn’t move.

White energy surged around him, flowing like living light. His eyes gleamed as he calmly raised a paw and pointed.

"Disperse."

The white current collided with the black beam.

The roar shattered.

The destructive energy unraveled, dissolving into nothing as if it had never existed.

Rowan lowered his paw, smiling faintly.

"You’re not the only one who’s immune to magic," he said softly. "So am I."
