"This mutt seems strong, I'll take care of this," Balak states. "No, this is the strongest being I've seen so far. You're going to need help," Kazuki says. "If Cerberus is this strong I don't want to find out how strong Hades is. Everyone, we need to work together to kill this thing."
"You're joking right?" Issei says. "I am very serious, now let's do this!" Kazuki threw a light spear at Cerberus, the attack did absolutely nothing. "Shit! Balak, command the shadows and try to take down this thing." He looks around at the countless hellhounds surrounding them.
He equips Rasaka's Fang and the Kreeton Cutter, and Kazuki charges at the hellhounds. The monarch was given help from Koneko and Akeno. Koneko used her impressive strength to dispatch the hounds while Akeno formed ice-shaped spears with her elemental magic to kill the hounds. The sadist flew up into the air, thunderclouds started to appear, and soon after lightning bolts were raining down on the hounds. The attack killed dozens upon dozens of them.
The rest of Rias' peerage was aiding the shadows in helping kill Cerberus. "I didn't expect a cerebus to be so strong. Although this one seems to be different from the ones in the underworld."
Rias formed a ball of destruction and threw it at Cerberus. Usually, whenever her destruction energy touches a living being they disintegrate. And when an opponent is too strong, it does not work. Cerberus attempted to claw at the devil but was stopped by Balak.
The demonkin slashed at Cerberus, damaging the hellhound. Igris does the same thing, and Viser attacks with her mace. All of them did little damage, Balak was the only one to put up a fight. But even he was too weak against Cerberus, In retaliation, the main head of Cerberus fired hellfire from its mouth. The devils moved out of the way in time but the shadows were not so lucky. They were all destroyed by the fire.
They all regenerated their bodies and continued to fight. The mass regeneration caused Kazuki's mana to decrease dramatically. The devils, fallen angels, and hellhounds that we're turned into shadows were also getting in on the action.
