Start by Becoming a Mangaka

"How did you come back?" Serafall asked. She had seen herself self-destruct during her fight with Azazel in a peace meeting with three factions.

"Hahaha, there is no way, I will tell you, idiot," Katarea laughed.

'Is it Sephiroth Graal?' Yuuki remembered this Longinus could reincarnate death.

The Sephiroth Graal, also known as Holy Grail of the Secluded World, is listed as one of the thirteen Longinus. It has the ability to make contact with the principle of life, where the possessor is being forcefully told about how life and soul are made. The possessor also takes in the mind and the concept of the dead, the living, and various other things as they use the Holy Grail which would result in the possessor being broken by the abundance of thoughts that enters their heart and soul when overusing the Sephiroth Graal.

From its power to control the principle of life, the Sephiroth Graal can bring the dead back to life.

Yuuki could only think of this possibility, he wasn't sure why Katarea suddenly came since he thought this was one of the worst time to start to have revenge since they had won from the Khaos Brigade, 'I need to destroy her soul then.' He remembered the Sephiroth Graal can also revive the dead as many times as the desire as long as the soul of the deceased remains intact.

"I will kill you Serafall!" Katarea said and shot demonic energy toward her.

"Sona-Chan protects everyone," Serafall said, and also shot her with demonic energy.

"Yes, Onee-Sama," Sona said while looking at the enemies. Her older sister had trusted her to protect everyone. Her demonic energy flared showing her talent in manipulating her trait magic at a young age. She knew that she couldn't hold back or else they would start attacking everyone. She created a water dragon and unleashed it toward the group of a magician.

The group of magicians wasn't a group of weaklings, together they made a barrier and blocked her attack.

"Hurry up and catch them, before the group of Onmyouji comes!"

"Yes!"

Their boss, Katarea ordered them to catch Serafall's little sister.

"Don't forget to catch the human too, I'm sure he is Serafall's toy boy."

"Hahaha, I can't wait to enjoy them."

"Attack her at the same time!"

"Fire Stinger!"

"Thunder Snake!"

"Holy Cross!"

"Energy Missile!"

Sona erected a barrier in front of her and blocked their attacks.

Boom! Boom! Boom!

Sona gritted her teeth to block this attack. She felt that it was too hard since their numbers were too much and most of them were quite strong, especially some of them had holy magic in their group. She needed to do something or else she would be defeated.

"Sona-Chan!" Serafall shouted until she was hit by something, "Kyaaa.."

"Ahahaha, I will kill everyone that you care about, Serafall," Katarea said with a wicked smile.

"YOU!" Serafall started to change and her body kept letting out very evil demonic energy.

"Hooo, you start to get serious, but it is futile since you will die here!" Katarea said while gathering her demonic energy.

"You will regret your choice," Serafall said and suddenly the temperature became cold. Her expression was very dark and she said slowly, "Celcius Coffin."

Katarea was very excited to kill her until she couldn't feel her legs. She looked down and saw her legs were covered in ice.

The ice didn't stop and slowly covering her entire body, she frowned and used more and more of her magic to destroy this ice only she couldn't. She looked at Serafall with anger and hatred, "SERAFALL!!!!" She kept this expression until her entire body was covered in ice.

Serafall sighed in relief and looked at Sona and Yuuki. She saw him take a silver gun out of nowhere and pointed it toward the evil magician. She didn't help them and looked at them with curiosity.

---

Sona couldn't attack and only in passive defense.

"Do you need my help?"

Sona turned her head and looked at him, "Can you?" She hoped that he could do something to help stop their attack and let her do the counter-attack.

Yuuki nodded and created a silver gun in his hand. He aimed his gun and shot it toward one of the magicians.

This attack didn't have any sound or light and they only realized that they were attacked when one of them suddenly disappeared.

"Eh?" They couldn't register what was happening until he saw them keep shooting at them and saw another person disappeared.

"R - run! Run!"

Everyone was panicked but they couldn't run from him and they disappeared one by one without having a chance to do something.

They looked at him in fear and felt regret for attacking him.

Yuuki wasn't going to let them run away and needed to kill all of them. He didn't want his life to become troublesome and needed to erase them from this world. He kept shooting without emotion until there was nothing left.

Sona opened her eyes wide, she couldn't believe it that and wasn't sure what it was. She only saw those magicians dissipate to dust, transform into steam and then scatter. She looked at the silver gun on his hand, 'Is it the sacred gear?' She decided to ask him later when he had done his job. She kept erecting her barrier to protect him while letting him kill them.

"Why don't you leave one?" Sona asked.

"I don't want to be known, it is better to kill all of them," Yuuki said. He closed his eyes and really needed to smoke a cigarette right now. He took a cigarette and started to smoke it.

Sona frowned, "Please, don't smoke, it is bad for your health."

"Okay," Yuuki said and ignored her.

Sona shook her head, "Is it the sacred gear?"

"Something like that," Yuuki answered vaguely.

Sona wanted to say something again until she heard her big sister's voice.

"Yuuki, Sona-Chan, are fine?" Serafall hugged both of them and placed them on her b.r.e.a.s.ts.

"O - Onee-Sama, please stop!" Sona blushed.

Yuuki wasn't going to be shy and needed some comfort right now.
