Grendel seemed wronged here, but he didn't care. "Hurry up and fight!" He was very impatient looking at them.
"I'll start!" Issei raised his Boosted Gear and said, "Ddraig!"
"Oh! Partner!" Ddraig shouted. He had woken up from his trauma and had turned back to normal. He saw Grendel and his blood was excited to fight this dragon.
[Balance Breaker!]
[Illegal Move Triaina!]
[Welsh Dragonic Rook!]
Issei was covered in red crimson armor with very thick arms. In this form, he possessed massive power and defense but had a low body maneuvering speed because of the massive, thickened armor. Even though it had a low speed, what he wanted to get was the power from this form.
Issei was powerful, even though he wasn't as powerful as in the original since his body was a normal human. Originally, his body was destroyed and it had been created once again by both Ophis and Ddraig. Making his body into a half-dragon and became stronger than before.
Everyone had high anticipation of Issei since this guy had always been unexpected.
"Finally, just come and hit me," Grendel said with an impatient expression.
Issei didn't disappoint him and charged directly toward Grendel. His booster boosted his speed and he raised his fist to punch Grendel's face.
*BAAAAMMM!!!*
They thought that this punch could defeat Grendel, however, they needed to be disappointed.
Grendel grinned, showing his sharp fangs in his mouth. "Is this it?"
"Then, I'll come once again!" Issei didn't raise his fist, but the booster behind his elbow and created a force similar to a hammer. "Solid Impact!"
*BAAAAMMMM!!!*
Issei had always been confident with his physical power, but it seemed that didn't work on this dragon.
"Ha! How boring!" Grendel raised his large fist and punched Issei.
*BAAAAAMMM!!*
The result was obvious, Issei was thrown and hit the wall on this field.
"Issei!!"
"Hyoudou!"
Everyone seemed very nervous when they saw the power behind Grendel since they knew very well how powerful Issei was in this Welsh Dragonic Rook form.
"You're too boring!" Grendel opened his mouth wide and sent out a blast of fire through his mouth.
Sona hurriedly used his water magic to create a large amount of water to cover everyone.
Fafnir, who had been summoned, also used his golden aura to cover everyone.
Shinra also used her Sacred Gear to try to reflect on the attack.
Koneko was the same and hurriedly changed into her other form using her magic item. She used her lance to destroy this large blast of fire.
The four of them combined their power with each other to block Grendel's attack.
*BOOOOOOOMMMM!!!!*
They knew very well that a dragon that had fought against Ddraig in the past was very powerful and it seemed that was right. They had successfully blocked Grendel's attack, however, they realized how powerful Grendel was.
Shinra's Sacred Gear broke instantly when she tried to reflect on Grendel's attack. Even though her power was able to reflect on an attack, it had a limit. She couldn't reflect on an attack that she was unable to handle.
Sona was also quite troubled since her expertise wasn't a power, but rather a skill. Her family's trait was water magic, but her power couldn't handle this dragon. She knew that she needed to work together with everyone to handle this dragon.
Irina and Asia went to Issei who was being thrown by this dragon.
"Issei-san!"
"Issei!"
"Cough! Cough! I am alright," Issei said and tried to stand up. His chest was hurt, but it didn't mean that he would stop fighting. He stood up once again and joined the battle. He felt very unsatisfied when he was thrown by Grendel's power. He was also quite dumbfounded since his attack didn't even put a scratch on this dragon.
"Koneko, can your power do damage to it?" Sona asked.
"I'll try," Koneko said and leaped very fast. Her movement was in an instant as if she was teleported directly.
Grendel was a bit surprised, by this little cat, but he was more excited to see the power of this little cat. "Come!"
Koneko slammed her lance in a crazed manner on Grandel's head.
*BAAM!* *BAAM!* *BAAM!*
Grendel was a bit in a daze when he received an attack from Koneko. Even though this attack didn't damage his skin, his brain was a bit shaken by the shockwave that was produced by Koneke's lance.
Sona saw a chance and said, "Hyoudou! Saji!"
"Yes, Kaichou!"
Issei and Saji moved in together at the same time.
Issei, who wanted revenge on this damn dragon, also moved and used his punch again in his Welsh Dragonic Rook form. If his punch earlier wasn't enough, then he only needed to punch this dragon more until he beat this dragon up.
Saji also used his line on his Sacred Gear to absorb Grendel's power along with burning him in the fire curse.
Three of them charged together using all of their power to attack Grendel together.
"Xenovia," Sona said. She could see that Grendel was unscathed and felt very uncomfortable since the defense of this dragon was too strong, right?
Xenovia knew that it was her time. She used her Balmung directly since she really loved this sword.
Fafnir who was Xenovia had taken Balmung seemed a bit agitated.
"Fafnir-san." Asia could feel that Fafnir was a bit agitated for some reason.
Fafnir looked at Asia for a while and looked at Asia's panties on his horn. He calmed himself, but he was still annoyed. [Asia-tan, I'll go back.] He had been slain by Siegfried with Balmung in the past and seeing that sword made him very uncomfortable. His body was engulfed in golden light and he teleported back to his home.
Sona was startled when Fafnir teleported back. She looked at Xenovia and knew that it might be because of Balmung on her hand. She knew the legend of Fafnir very well and understood why he decided to go back. She knew that the power of this dragon was very powerful and she looked at the amulet that Yuuki had given to her.
"Balmung!"
During Sona's deep thought, Xenovia used Balmung right away to slay Grendel.
*BOOOOOOOOOMMMMM!!!!!!*
