Boom!
A fierce duel erupted between the Governor of the Fallen Angels and a pure-blooded descendant of the former Demon King.
Their clash unleashed a wave of destruction and terror that rippled across the battlefield.
Sirzechs, Serafall, and Michael watched the spectacle in silence, showing no intention of interfering.
"Onii-sama, allow my peerage to handle them."
Rias stepped forward, her voice ringing with authority.
"Very well. Be careful."
"Thank you, Onii-sama."
Rias offered a soft, radiant smile, looking toward her family before shouting, "Let's go!"
"Right!"
Rias's peerage charged out from the safety of the barrier, engaging the terrorist forces that far outnumbered them.
Sona sought permission from Serafall, though it took several minutes to convince her overprotective older sister to let her join the fray.
Eventually, Sona's peerage moved in tandem with Rias's family to push back the terrorist onslaught.
Not to be outdone, Heaven joined the fray as Michael personally dispatched Irina to assist the two devil houses.
Sirzechs cast a subtle glance toward Vali.
"And what about you?"
Vali simply shrugged. Donning his Balance Breaker armor, he lunged forward, obliterating any terrorist who dared stand in his way.
Issei, refusing to be left behind, also activated his Balance Breaker armor and began a rampage across the battlefield alongside Vali.
Boom!
A massive explosion shook the area, drawing everyone's attention toward the epicenter of the blast.
'Katerea blew herself up? How is that possible?'
Issei stared straight at Azazel, shocked to see the old man heavily wounded and struggling to maintain his flight.
A white flash streaked toward Azazel. Reacting instantly, Issei charged in full armor and collided head-on with the white light.
Boom!
The collision of crimson and white auras generated a powerful shockwave that swept through the surroundings.
Even Azazel was sent tumbling by the impact, landing roughly on the ground.
"Ouch, that actually hurt. Were you guys trying to kill this old man on purpose?" Azazel quipped.
Vali stared intently at Issei.
"You're strong."
"So are you."
"Kukuku, it seems you already knew I was going to defect here," Vali remarked, a hint of admiration for Issei in his voice.
"Of course. As if a battle maniac like you would sit still without causing trouble."
"You certainly understand me. In that case—Divide!"
"Boost!"
Issei and Vali faced each other in a tense silence.
"Everyone, get back here now!" Sirzechs commanded.
The peerages of Rias and Sona, along with Irina, immediately retreated behind the barrier.
Boom!
Issei was suddenly enveloped in a crimson aura far greater than anything he had shown before.
Vali unfurled his devil wings, flaunting his demonic power for all to see.
"I knew the reports, but seeing it in person almost makes me want to laugh," Sirzechs murmured with a serious expression.
"Hahaha, I feel the same. Seeing a reincarnated devil become this powerful and master the Boosted Gear... just who is your brother-in-law, anyway?"
Azazel appeared out of nowhere, his body still battered.
"I don't know. All I know is that he is the future of this world."
Even Michael looked surprised by Sirzechs' answer.
"A future without God... I wonder what that will look like," Azazel whispered softly.
Boom! Boom! Booom!
Explosion after explosion rocked the air as the crimson and white auras collided.
The Dimension Lost realm trembled, unable to fully contain the sheer impact of the two Heavenly Dragons fighting.
Vali caught Issei's fist mid-air.
Divide! Divide! Divide!
Boost! Boost! Boost!
Albion and Ddraig were frantically pushing their abilities to the limit.
Albion halved the opponent's power every ten seconds.
Ddraig doubled his user's power every ten seconds.
As long as they kept dividing and doubling, this battle could theoretically last for eternity.
Issei had no intention of letting it drag on, so he deliberately kept his distance while continuing to double his strength every ten seconds.
"Partner, this will never end. Even if you keep your distance, Albion can still halve our power."
"Tsk! How annoying!"
"What's the plan? Planning to use Juggernaut Drive?"
"No, I want to try something else."
"And what would that be?"
"...Ddraig, the moment I shatter Vali's armor, you need to boost my power immediately. Got it?"
"Partner, don't tell me you're trying to erase Albion?"
"No! I'm just going to erase his armor!"
"Oh? In that case, I'm in."
Issei gave a small nod.
Vali approached, sounding skeptical.
"And just how do you plan on stripping me of my armor?"
Issei raised his right hand.
"With this—Mist Dispersion Ex!"
"Vali! Get out of there!" Albion roared in warning, but it was too late.
The wave of Mist Dispersion Ex slammed into Vali, disintegrating his armor in less than a second.
"What happened?!"
Boost! Boost! Boost! Boost! Boost!
A majestic power surged through Issei's body.
Without giving Vali a chance to recover, Issei lunged forward and delivered a merciless beating, leaving Vali's face covered in blood.
