Yuuki was teleporting together with Rossweisse, Kunou, and Yasaka. He took control of three gigantic monsters before teleporting them to the realm of the dead, where it was the home of both Hades and the Grim Reapers. He was confident that Azazel and Sirzech wouldn't get into a fight with Hades and it would also be very hard to put blame on Hades since there wasn't any evidence or proof that Hades had colluded with the Khaos Brigade. He also knew that it wouldn't be easy for those who had the power to fight each other since the result of their fight would be devastating.
'Concern, huh?' Yuuki started to think about what to do with the Hero Faction. He knew that it was impossible to change their mind and after what they had done it was impossible to be forgiven. He knew that he couldn't be merciful toward them. He thought that he should end them when he had a chance in the past.
"You've got three of them," Rossweisse said.
"Papa, you're very strong," Kunou praised.
Yuuki smiled and patted Kunou's head, "If I am not strong, I won't be able to protect you."
Yasaka shook her head and said, "You don't need to push yourselves. I can handle the rest of the monster along with everyone."
Yuuki thought for a while and felt that he was the one who had done the job. He felt that he should leave some of the monsters to the other people. He nodded and said, "Let's visit, Serafall."
"Good," Yasaka agreed.
"I'll open the portal to get there," Rossweisse said and created a constellation portal for Serafall's location.
They entered the portal and teleported to the location where Serafall along with her subordinatres were fighting against the gigantic monster.
"Huh? Yu--- Archer! What are you doing here?" Serafall was surprised when she saw four people appearing beside her. She wanted to call his real name but she corrected herself since she knew that he wanted to hide it.
"We're coming for help," Yuuki said.
"Eh? How about the monster in your place?" Serafall asked.
"This guy has defeated three of them," Yasaka said.
"...."
"3?" Serafall felt that she would lose. She thought for a while and said, "No. Let me, The Magical Girl Levia-tan defeat this monster!" She also wanted to show him her power since she wanted to recruit him to her peerage. She started to fly toward the monster while getting ready to use her magic.
Yuuki was also curious about the power of Serafall and decided to watch in silence.
"Archer, do you know what Serafall's magic is famous for?" Yasaka asked.
"Hmm, I am not sure, but it should have something to do with water, right?" Yuuki said. He remembered that the Sitri Family was famous for their water magic.
Yasaka nodded and said, "Yes. The Sitri Family is famous for water magic, but Serafall is special since she is famous for her mastery of ice magic."
"Ice magic, huh?" Yuuki was wondering who was stronger Yasaka or Serafall but he knew that it was better to shut his mouth now.
Rossweisse was also curious about the power of Serafall since she was known as one of the four Maous.
Serafall wanted to show her cute magic on him and took a deep breath before a large magical circle appeared right in front of her. She closed her eyes for second before saying, "Celsius Cross Trigger!"
Then it was just a moment that the land in front of them had turned into the world of ice and she froze up an entire region of the Underworld, along with the Jabberwocky that had been created by Anhilitation Maker.
Everyone only looked at this magic in awe until they felt a cold temperature on their bodies.
"I am cold," Kunou said while hugging her body.
Yuuki created a coat for Rosswseisse, Kunou, and Yasaka since he had to admit that this magic wa very strong.
"Thank you, Papa!" Kunou smiled and wore a warm coat immediately.
"Thank you," Yasaka also said while smiling at him.
Rossweisse blushed while giving him a peck.
Yuuki caressed his cheek and thought that there were a lot of problems lately. He looked at the sky and shouted inwardly, 'I want to go back!' Though, he couldn't do that until he had settled the problem in this place.
"How is it?" Serafall asked after she had defeated the monster.
"You should have used your magical stick when you attacked that monster earlier," Yuuki said.
"Oh, right! How can I forget about it!" Serafall said and wrote it in the memo.
"......"
Yasaka and Rossweisse were speechless at their conversation.
"Do you want to come to hunt another gigantic monster?" Yasaka asked.
"Sure," Serafall nodded since she felt that it was faster to travel along with them.
Yuuki suddenly felt something and said, "I'll go somewhere first."
"Where are you going?" Rossweisse asked.
"Help someone," Yuuki said.
"Then we'll come too," Yasaka said.
"Don't you want to take care of the monster first? I'll come back as soon as possible later," Yuuki said since he didn't want to show Kunou his other side. He patted Kunou's head and said, "Let's play after this matter is over."
"Uhm," Kunou nodded in response.
"Take care," Yuuki said and gave a peck to both Yasaka and Rossweisse.
"How about me?" Serafall asked.
"......"
Yuuki looked at Serafall for a while then gave her a peck on her cheek. He separated from them before saying, "Then, I'll go now." He entered the black portal and teleported somewhere.
Serafall caressed her cheek and then said, "Yosh! Let's defeat the monsters that have caused trouble in the underworld!"
"Yeah!" Kunou cheered.
Rossweisse and Yasaka only shook their heads at the same time.

Pierce!
Yuuki stabbed Siegfried right into his heart with his bare hand. He created a handkerchief while saying, "Kiba, you can have the sword."
