Rias and Akeno did their best but Raiser just continued to regenerate like no tomorrow while attacking them with firebase attack.
Raiser haughty said," Just like I said just stop doing this, you can't win against an immortal like me ~"
Rias make a large ball of Power of Destruction, throw and successfully destroy on of his hand but he just regenerates it fast.
" Ha…. Ha …. Ha ….. This is not good Akeno, I think I almost reached my limit," Rias said.
"Me too, the phoenix clan ability is like a cheat, even if we bomb him like no tomorrow, he's just going to regenerate it," Akeno said.
" But we can't stop, I am going to use my trump card now!" Rias said.
"You know that you did not need to do that, we have Xin-kun right?" Akeno said.
"You are right we have Xin-kun that's why I'm doing my best! I don't want him to see me as a weak woman!" Rias insisted.
"Ara ~ Ara ~ you're starting to get worried how Xin-kun sees you? That not good Rias, Xin-kun is mine ~" Akeno said.
Rias looked at him and righteously said," No he is mine, he is my pawn!"
"You are right, but what will happen after 3 days? Fufufufufu ~," Akeno said.
"You don't need to worry about that, I'm going to get him after 3 days!" Rias said.
"Well ~ you wish," Akeno said.
"Hold him down," Rias said.
"Okay," Akeno started to generate thunder in her finger and shot it to Raiser.
"Lightning Bind"
Raiser successfully bind by a thick Lightning rope, he try to escape but the Lightning rope is too powerful.
Rias starts gathering a gigantic ball of Power of Destruction, she compresses it to make it smaller and this not only can make Power of Destruction more powerful but explosive too.
Meanwhile, Akeno gathers a gigantic ball of Thunder and Lightning, she feels excited that her power has almost doubled after that training, she can't wait to show off in front of others and of course to Xin.
"Power of Destruction: Black Dragon of Destruction!"
"Thunder and Lightning Dragon!"
A large black dragon made by Power of Destruction and a dragon made by Thunder and Lightning fly straight to Raiser.
Raiser's hair stands up when he see the two attack, he feel that this time he will lose. But because of his pride he will never bow down to others much more than a woman.
He uses his maximum power and gathers fire from the phoenix to defend.
"You can't defeat me, Rias!!" Raiser shout.
"Hell Fire: Hell Phoenix"
A huge firebird appears and tries to swallow the two attacks, but Raiser underestimates the attack he is actually being pushed by.
He try to fight back but the Power of Destruction starts to destroy his body while Thunder and Lightning make his body numb.
Then Raiser devour by the two ultimate attacks,
"Aaaaa!!!!!!!!"
"BOOOMMM!!
Rias and Akeno feel relief when they see Raiser hit by their combination attack, the only thing that they are hoping is that Raiser will not survive from that attack.
"Ha…. Ha …. Ha ….. That's... a good attack ability Akeno," Rias said while panting.
"....Ha…. Ha …. Ha ….. You too Rias…. I did not expect that either," Akeno said.
Asia, who was hiding not far away, ran to help them to restore their stamina.
Akeno looked at Asia and said," It's good that we have a good healer.."
"N-No I'm not good enough, I still need to train, Akeno-san." Asia embarrassingly said.
Rias patted her read and said," Why not become my permanent peerage Asia-chan?"
"Ummm.... I can't do that, I want to... to follow Xin-kun," Aisa shyly said.
Suddenly they hear a nasty laugh," Fufufufu do you guys think that you won?"
They look up and see Raiser who almost looks like a beggar still alive, they did not expect that he would resist that combination attack.
"I'm tired of this game, let me finish all of you!" Raiser said and made a giant ball of fire and shot at them.
The three girls unconsciously close their eyes and wait to be hit by the attack but they hear a calm voice.
"Why are you guys closing your eyes, you can't win if you not open it"
They open their eyes and see Melan hugging Xin behind while Xin calmly touches the ball of fire.
Xin said," You guys did a good job, but the phoenix clan ability is like a cheat likeability"
"If you guys want to win to him you need a thing, and that is overwhelming power that can erase him in the face of the underworld without giving him time to recover"
"And the other is to seal his ability so that he cant regenerate again"
Xin then flick the giant fireball back to Raiser.
"You are here Pawn-kun~ do you want to get beaten too?" Raiser said while deflecting the fireball.
He don't know why he feels somehow scared from the woman behind him but just like the author said a prideful person became an idiot because of his own pride.
"Melan, you can put me down now, and I want you to try to subdue that chicken man." Xin said.
Melan reluctantly put down his master,"…. I will subdue that.... chicken man master… "
Asia, Rias, and Akeno look at him, they were curious how strong Melan really is. Now they have a chance to see her prowess.
