Katerea was undeniably strong. Her attacks weren’t limited to simple magic projectiles; as a Devil, she could make full use of the demonic power in her body and convert it into various sophisticated offensive spells.

Furthermore, her ability to mobilize so many mages for this attack showed her deep connection with the magical world.

In addition to spells specific to Devils, Katerea also possessed a wealth of magic formulas. Her flexible and ever-changing incantations made her a difficult opponent to handle. Roy couldn’t kill Katerea as quickly as he had killed Kokabiel.

After all, her main power at the moment came from Ophis, the Infinite Dragon God. Power at that level meant that even if Roy used the skill Envy, it couldn’t be fully sealed. Katerea’s flexible spells also made Envy less effective; even if one spell was sealed, she would simply switch to another.

Of course, if Roy used Rage and Aeriel, his strength would increase enough to suppress her, but there was no immediate need to rush.

Because Katerea was one of the few who knew so many different types of spells, Roy decided to use the time to secretly learn them. At this moment, Roy’s Arcs Magica and Omniscient were active, allowing him to memorize her magic formulas as quickly as possible.

“Stinking brat, wipe that arrogant look off your face!”

Irritated by Roy’s calm demeanor, Katerea began to attack him crazily. Layer upon layer of magic circles emerged around her, and she poured her surging demonic power into them like water.

So magic can still be used like this? Roy felt he was learning something new. Katerea was using different spells simultaneously and then linking them with a special technique, superimposing their power to a level far exceeding their original capacity.

This usage had a drawback, it consumed a massive amount of mana but that was nothing to Katerea. After all, the power given to her by Ophis allowed her to use this secret technique without any scruples.

“Are you laughing at me, brat?” Katerea’s state of mind was very sensitive, and Roy’s silence felt like mockery to her.

“Die!” she shrieked. Her magic was ready in an instant. The violent and terrifying spells poured out from the magic circle, drowning Roy immediately.

“Roy!” Rias cried out, her face pale with worry. The power behind that attack had already surpassed the standard for a Maou class entity.

“Don’t worry, that brat is tougher than he looks,” Azazel said leisurely. “With Katerea’s strength, it’s impossible to take him down like that.”

Just as he predicted, when the magic light faded, Roy stood revealed.

“Unscathed…” Katerea muttered, her eyes wide with disbelief. That was her most powerful strike, and it hadn’t caused any damage. Roy was wearing his crimson armor, with a layer of emerald green wind from Aeriel still swirling around it.

“It wasn’t exactly ‘unscathed,'” Roy said lightly. “At least my Via Shilheim was completely destroyed by your blow, and even the wind wall from Aeriel was broken.”

Between the Boosted Gear, Via Shilheim, and Aeriel, Roy’s defense was nearly impenetrable. Even Katerea’s amplified attack couldn’t pierce all three at once.

“Is that the end of your tricks? It’s time for me to pay you back.” Roy’s aura suddenly rose, and the emerald wind of Aeriel appeared again. Roy activated Rage and Aeriel together, pushing his power to a new level, though he noted the relative increase felt smaller now.

Is it because my Falna is still only Lv.5? he wondered. The skills developed through Falna were growth-based, but his strength was currently being pushed to the Maou level by his Balance Breaker.

Because his base level hadn’t caught up yet, the boost from Aeriel at Lv.5 wasn’t as effective as it used to be.

Sensing Roy’s jump in power, and looking at the leaders of the three factions below, a look of desperation finally crossed Katerea’s face.

“I won’t die for nothing! I’m taking you with me!” She turned her arm into a mass of writhing tentacles, lashing out with unavoidable speed and binding Roy tightly. Simultaneously, strange, glowing lines appeared on her body.

“Damn it! That…!” Azazel shouted.

“A self explosion technique,” Sirzechs said, his expression darkening as his Power of Destruction rose. A self explosion at this level, fueled by Ophis, would likely be twice as powerful as her previous spell. If she succeeded, Roy would be in grave danger.

Sirzechs prepared to intervene, but Roy’s voice rang out. “I’ve been waiting for this.”

At that moment, the power of Envy was fully activated.
