Start by Becoming a Mangaka

Siegfried was standing in front of them along with a number of members of the devil from Old Satan faction.

"You have come to be killed, huh?" Akeno said.

Koneko didn't hesitate and used her power to transform before leaping instantly into one of her opponents, destroying him instantly.

BOOOOM!

"Damn!"

"Strong!"

"Kill her!"

The group of the devil from the Old Satan faction who saw this scene hurriedly prepared their magic to kill Koneko.

"I won't let you!"

Akeno and Rias sent out their magic toward the devil of the Old Satan faction.

Before long they started to fight each other leaving only Siegfried who was watching this situation calmly.

"I'll be your opponent," Kiba said and faced Sigfried.

"Yuuto Kiba, huh?" Siegfried only looked at Kiba for a second before continuing to watch Rias, Koneko, Akeno, and Xenovia who fought against the group of the devil from Old Satan faction.

"Bastard!" Kiba moved very fast and appeared right in front of Siegfried before slashing his sword.

Siegfried summoned four arms on his back and blocked Kiba's attack. He frowned and could see that Kiba had become stronger. He decided to play for a while observing the situation of his surroundings. 'That half-fallen angel and cat youkai is the stronger one, huh?' He thought inwardly. He thought that the group of the devil from Old Satan faction would be quite strong but it seemed that they were just crap. He jumped back and kept his distance from Kiba, "You've become strong. It seems that I need to get serious or else I won't be able to get out of this place unscathed."

Issei worked as a supporter, giving everyone a "boost" using his Boosted Gear. He suddenly saw Siegfried take out something similar to a pistol but with an injection on its tip from his pocket, "What's that?"

Siegfried took the needlepoint to his neck before smiling, "This is something that was complete with the help of the old-Maou Shalba Beelzebub. In other words, it's a doping drug. For the Sacred Gear that is."

"You're going to use that to strengthen yourself?"

Siegfried nodded then said, "What would the result be if we were to inject ourselves with the blood of the true-Maou who is the arch-enemy in the Bible of the God who created the Sacred Gears? That was the theme of the research. With quite a number of sacrifices and lots of data collected, it was able to fuse between the Sacred item and deep devilishness."

Blood of a Maou!

Everyone seemed surprised when they heard such a thing appeared in this world.

Siegfried then looked at the Gram which he was holding onto. "Naturally I should be able to defeat you with this Demonic-Emperor-sword Gram... Unfortunately, I am chosen by this sword but you can say that I am also cursed by it. Kiba Yuuto. You can understand what I mean, right?"

Siegfried's Sacred Gear is a sub-species of [Twice Critical]. Its Balance-Breaker is also a sub-species. His Sacred Gear is said to be a dragon-type Sacred Gear, and just like the name implies, it has the traits of a Dragon. He won't have a problem wielding Gram if it's Twice-Critical in a basic state. But it will be a different story if it is a Balance-Breaker which skyrockets his abilities. The more he increases his abilities, the more his relationship with Gram worsens. The more Siegfried releases his true ability, the more harmful effects it has on him because of Gram's Dragon-slayer ability which will terminate Siegfried himself.

"I will receive fatal wounds by my own sword if I am in a Balance-Breaker state. This sword here isn't concerned about my body." Siegfried lamented looking at Gram before looking at them. "Yes. If I want to fight using Gram, then I have to fight in my normal state. But compared with the Balance-Breaker six-swords style, it won't cope with it. And that becomes more obvious in a battle against you guys. I won't be able to fight against you guys properly if I don't use Balance Breaker. But it will be a different story if I can use the Demonic-Emperor sword Gram while in Balance-Breaker."

Siegfried injected the contents of the pistol into his neck. Then Siegfried's body reacts. His body started to react even more, and his body started to change.

Michi! Michi!

While making a weird and dull sound, the four arms growing from his back became thicker. Each of his fingers started to crumble and merge with the swords they are holding onto. Siegfried himself started to change. His expression became hard and there were veins on his face. His muscles started to move as if he was a different creature and the hero-faction uniform he was wearing got torn. A monster who had four arms that became gigantic which can almost touch the ground. He no longer looks like an Asura. He now looks like a spider monster. The enormous pressure and creepy aura weren't normal. While having cramps on his face, he smirks.

"Chaos Drive. That's what we call it. We call this doping injection a "Chaos Break". We took the part of the name from "Balance-Breaker" and "Juggernaut-Drive"."

Siegfried's low and deep voice could be heard by everyone, his voice also changed along with his transformation.

Monster.

Yes, Siegfried has transformed himself into a monster itself.

They could feel the power that emitted from Seigfried's body was so powerful that it was even stronger than the group of devils from the Old Satan Faction.

Akeno, Rias, Xenovia, and Koneko were fighting against the group of devils. Only both Kiba and Issei were able to fight Siegfried who had turned into a monster.

Asia was behind them while trying to help them only when she suddenly saw a black portal appear behind Siegfried.

Pierce!

"Wha---- Cough..." Siegfried coughed a lot of blood from his mouth and saw a hand had pierced his heart directly.

"You need to say that line when you have the confidence to win against them...."

"Though, it is impossible."

Splash!

Siegfried dropped on the ground while looking at the person who had killed him, "You...." He wanted to say something but he felt tired and closed his eyes. He couldn't stay in this world again but he felt that he had angered someone that he shouldn't be.

Yuuki came out from the portal alone while cleaning his hands with a handkerchief. "Kiba, you can have the sword."

"..."
