His attack hit him only a few centimeters away.

Yuuki calculated the energy, trajectory, speed, and many important aspects of this attack and bounced it back. He also made this magic more powerful than before.

Shalba was startled but he had a lot of fighting experience. He dodged his attack while looking at him with a worried expression.

BOOOOM!!!!

That magic hit the castle and almost destroyed it.

“Hurry up and go,” Yuuki said to them.

They still felt reluctant but they knew that they couldn’t be helped and would only become a burden for him.

“You need to come back,” Rias said.

“I won’t forgive you if you don’t come back to me,” Akeno shouted.

Koneko also wanted to say something but decided to keep silent. She knew that she needed to get stronger or else she would only be a burden for him.

Issei and Asia still fainted and both Kiba and Xenovia carried them to get away from their battle.

Shalba looked at him and asked, “Who are you?”

“Archer,” Yuuki answered.

“Archer?” Shalba looked at him with a confused expression since he didn’t see any bow on his hands. He snorted and said, “Whatever, I will show you the power of true devils!!!”

“Hoo, interesting, shows me how strong a true devil is,” Yuuki said to him.

They looked at the destroyed castle and the area around them. They saw massive demonic energy kept destroying the area. They couldn’t get close to the battle and could only look from far away.

“Hooo, they’re fighting, they’re fighting.”

Suddenly the Gremory group noticed the appearance of Vali Group. They saw Vali, Bikou, Arthur, and Kuroka looking at the battle with popcorn on their hands.

“Nee-San,” Koneko called her sister.

“Shirone, nyaa,” Kuroka nodded and looked at the battle.

“Is this okay?” Kiba asked. He looked like the one who attacked was Shalba and Archer didn’t do anything.

“It is okay, he is probably thinking about something right now,” Arthur said while adjusting his glasses.

“Huh?” They looked quite confused when they heard it.

“It means that he is only testing something now,” Bikou said.

“Testing, huh?” They looked at the battle and sighed. They thought they were strong but it seemed they needed to train harder.

Vali noticed something strange on the boosted gear of Issei. He turned his head suddenly Ophis appeared on his side. He saw Ophis took out some black gas from the boosted gear on her hands, “What is that?”

“It was inside of him,” Ophis said and absorbed it in her hand.

No one noticed that she had taken this black gas from Issei.

Issei opened his eyes slowly and shouted, “ASIA!!!”

“Issei, calm down, Asia is here,” Rias said.

Issei turned his head and saw Asia was in Akeno’s arms sleeping soundly, “Asia….” He was crying in happiness when he saw she was fine. He suddenly noticed a battle in front of him, “Who is fighting?”

“Shalba and Archer,” Xenovia said.

“They have been fighting for a while,” Kiba said.

“Bastard….” Issei was angry when he remembered Shalba. He tried to get up slowly and only fell down on the ground.

“Issei,” Kiba caught him on his arms. He looked at him with a helpless expression, “You’re still weak, don’t force yourself.”

“But that guy is still there!!!” Issei said.

“You don’t need to worry that much, partner, the battle will be over soon,” Ddraig said.

“Do you mean?” Issei looked at the battle with a serious expression.

Shalba was really annoyed when his attack bounced back on him and several times stronger than before. He kept attacking and dodging at the same time. He had seen someone in the past that could reflect someone magic and made it stronger but he had never seen someone that could do this a lot of time.

“DIE!!!!” Shalba decided to use his ultimate magic. He released his magic bees on his body and decided to take over this battle.

His ability to manipulate bees is a nod to the demon Beelzebub’s title as “Lord of the Flies” and his ability to control all families of flies.

Shalba could control any kind of flies but these bees were his favorites. He released thousands, ten thousand, hundred thousand, until millions of bees to fight to kill him. He knew that this guy could reflect any attacks but could he reflect on these millions of bees.

bzzzt! bzzzt! bzzzt!

These bees were very loud and they were very aggressive, each of them had magic energy similar to Low-Class Devils but when it combined it even reached the Demon King level.

Shalba was confident that he could kill him and continued to destroy the Underworld.

“That’s crazy!!!” Xenovia said while looking at those millions of bees.

“Bikou, his power is similar to yours, nyaa,” Kuroka said.

Bikou felt complicated since he couldn’t control that much of bugs. He shook his head and said, “Don’t forget that those bees are small, it is different from my fungus.”

“But can you defeat him?” Arthur asked.

Bikou snorted, “Of course I can, but it won’t be an easy fight.”

“Hmph, you talk big, nyaa,” Kuroka said.

“What do you say?” Bikou got pissed.

“Shut up,” Vali said.

“Yes…” Kuroka and Bikou said at the same time.

Vali shook his head while looking at the battle. He wanted to know how strong Yuuki was since he had never seen him get serious on the battle. He looked at the Red Dragon Emperor and sighed. He wanted to fight his rival but it seemed this pervert needed sometime before it had reached his standard.

At that time, Vali was sure that he had gotten several times stronger than Issei. He shook his head and decided to think about it later.

Everyone was watching the battle with various expressions and they hoped for him to win.
