Start By Becoming A Mangaka

Yuuki looked at both Naegling and Hrunthing which had turned into blood-red while glowing a dim blue light. He knew that both of those weapons were ready to burst, but he knew that it wasn't enough to one-hit-kill this legendary dragon. He also decided to use a move that he had gotten from a reward in his quest in the past.

King Punch.

Yuuki remembered that it was the move of Elizabello from One Piece that could even create a lot of damage to Yonkou.

Everyone in One Piece's world knew that "King Punch" from Elizabello was very destructive.

Yuuki applied "King Punch" on both of his hands before he smashed both Naegling and Hrunting that were ready to burst at the same time to create more damage on Grendel.

"You're alright?" Jeanne asked.

"I need time to prepare something," Yuuki said while preparing his attack.

The only disadvantage of this technique was that it needed a lot of time to prepare.

Yuuki remembered that Elizabello needed one hour to warm up before he could pulverize everything with his punch. He didn't need that much of a long time, but five minutes was a very long time.

Issei had changed back and used his Boosted Gear to boost everyone's power, especially to Kuroka, Koneko, and Xenovia. He knew that the three of them had the highest strength power.

Saji continued to use his Sacred Gear to absorb Grendel's power and stamina while also channeling it to everyone. He could only support everyone in this situation. He sighed when he thought that he couldn't use his Balance Breaker and it made him very vexed at this moment. He looked at Yuuki who was giving powerful momentum. He was curious about what Yuuki wanted to do, but he didn't ask him since he was afraid to break his focus.

Sona and Jeanne were working together to stop Grendel while also giving time for Xenovia, Koneko, and Kuroka to use their ultimate technique.

Jeanne created two large dragons that were made from Holy Swords.

The two dragons worked together to attack Grendel at the same time.

Sona, who didn't like the holy aura from Jeanne's dragon, could only say that Jeanne was quite dependable in this situation. She created a large serpent to tie Grendel in place, making him unable to move. "Koneko! Xenovia! Kuroka-san!"

Xenovia, Koneko, and Kuroka were ready with their preparation.

Xenovia raised both of her Durandal and Balmung at the same time before creating two enormous lights that combined together giving an aura for the opposition.

Koneko also created a gigantic blue light sword from her lance ready to attack at the same time.

Kuroka created a large dragon that was made from white flames.

"Durandal! Balmung!"

"Bard Longineus!"

"Astor Inqerad!"

Their attacks started to combine with each other, creating a combined three swords with a white flame dragon that swirled around it.

Everyone who saw the combination attacks of the three of them could only open their mouths in awe since they could feel the powerful power behind this attack.

Issei, who saw the combination of their three attacks, started to use his Boosted Gear to strengthen their attack.

[Boost!]

Their attack grew bigger and it slammed directly toward Grendel.

Jeanne and Sona had hurriedly backed away from Grendel, who would receive their combination attack.

Grendel, who had turned crazy, didn't care about any attack that was sent toward him. He was proud of his defense and he would show them that this attack was useless. "OOOOOOHHHHHH!!!!!!" He opened his mouth and sent out a breath of flame.

*BOOOOOOOOOOMMMMM!!!!!*

Grendel's flame attacked the combination attack, but it didn't stop that attack.

Grendel charged toward the attack and blocked the attack with his punch.

*BOOOOOOOMMMMMMM!!!!*

Everyone closed their eyes when Grendel was hit by the combination attack.

The shockwave that was created from it was so powerful that it shook the field and made everything into ruin.

It was surely a luck that the stray magician had strengthened this place with their magic or else the combination attack would destroy everything.

Issei, Saji, Xenovia, Sona, and Koneko were very tired at this moment. However, their expression seemed to be very relaxed since they thought that they had defeated this dragon.

"It's not over, nyaa," Kuroka said with a serious expression.

Grendel came out of the ruin with one of his hands mangled after receiving their combination attack. His one eye was red and he looked at them with a very angry expression ready to kill them.

They felt a bloodthirsty aura that came out from Grendel that made their legs weak. They didn't expect Grendel to be alive from their combination of attacks. They had used their everything, but they couldn't defeat this legendary dragon.

Kuroka stood up in front of everyone since she knew that she was the only one who could buy time for Yuuki to send his attack.

"ROARRRRRRRRR!!!!!!!!"

Grendel roared loudly, making their eardrums almost burst.

They weren't sure what to do at this moment and could only put their hope on Yuuki.

Grendel charged toward them while opening his mouth to eat all of them. He was very angry and he wanted to eat them. He also wanted to torture them and showed them what it meant to make him this angry.

They were in despair when Kuroka had a serious expression while summoning another dragon that was made from white flames.

"I'll handle this."

Suddenly Yuuki appeared in front of everyone and his two weapons had turned into bright crimson that seemed ready to burst in an instant.

Grendel, who saw Yuuki, turned his anger toward him. He really hated him and after that, he would also kill everyone that he loved in this world. "DIE!!!!!"

"No, you're the one who is going to die."

Yuuki leaped and raised both of his weapons at the same time toward Grendel's head.

"Grendel....."

The muscle on both of his arms was tightened to the limit and it seemed almost bursting.

"Buster!"

*Splash!*

It sounded similar to a watermelon that was smashed to the ground with a lot of power.

The moment Yuuki, who had used a technique of "King Punch" on both of his arms slammed both of Hrunting and Naegling into Grendel's head.

Issei and Saji closed their eyes instantly and felt something warm and wet on their faces and body. Both of them opened their eyes and couldn't help but wanted to puke since they saw the scene in front of them.

Grendel, who was known as a legendary dragon, had turned into messy mush on the ground.
