"...Azazel... Please explain what's happening..." Vali couldn't believe that the people he was looking down on just now started to push back Kokabiel, a leader of one of the biggest factions in the world. He couldn't fathom how they suddenly powered up as he could tell it isn't from a Sacred Gear or something he could see.

"... I don't know... tch." Azazel is currently staring at Aika's current form. Koneko also caught his interest, but not as much as Aika. He has a clue on what Koneko had become, but in Aika's case, it is totally unknown to him. He wouldn't dare think that he knew everything in the world especially those on top of the power ladder, but Aika is only a normal human in his eyes not long ago and even after her transformation, she isn't that very strong, 'Did a new power rose up somewhere and didn't notice it until this point? And where did that nodachi came from?'

As he is currently watching him taunt Kokabiel, Azazel also managed to pick up some information, "Urahara Shop... is it? I need to take a look at it later... No that I think about it, there are also some rumors about a powerful but unknown individual with never before seen power system appeared in the Underworld... It seems that there is some truth to it.'

Azazel smiled at the prospect of a new player coming in, 'Now then... It seems they have some power and they could be useful. Sooner or later, someone would think of unsealing that thing, if not, then I would have to make someone do it...' Thinking of his future plans, Azazel's smile suddenly froze when Aika's aura suddenly raised multiple times and her nodachi suddenly changed into twin swords which are emitting two very distinct familiar but also unfamiliar aura, "Impossible!"

"What!? What happened?" Vali is also surprised by Aika's sudden second transformation, but he's more surprise at Azazel getting 'too' surprised.

Azazel didn't answer him and his mind started running at full speed, 'I can't be wrong! Those are Great Red Dragon and Ouroboros Dragon's aura... They are... but somehow, it's also different... very different.' He didn't know how to judge the current our emitting from her, but he knows one thing for sure, 'She was able to awaken those two partial souls from Great Red and Ouroboros... I already tried and studied it in the past multiple times and I already gave up, but somehow, she managed to do what I can't all those years... Dammit! I want to go, but I can't step on Kuoh Town yet! I should have sent those Peace Conference invitation earlier!?'

They watched in fascination as Aika suddenly appeared on top of Kokabiel's head and blasted him with a black and red wave of energy.

Kokabiel blocked it with his spear of light quite easily, but to his shock, his spear of light was being corroded and consumed by the wave of energy. He also noticed that his movements are a bit sluggish like something is trying to lock him in place.

She threw off Aika using his superior strength and renewed the spear of light in his hand. From there, they had multiple exchanges which resulted in some of the school buildings collapsing from their clashes. Using this chance, Aika also destroyed the magic circle from fusing the four Excaliburs using her energy blast to stop it from gathering mana.

"W-what's this?" Xenovia blankly asked. She's still thinking if this the same girl she just sparred before, 'She's been holding back this much?' She felt funny boasting her 'trump card' in front of her.

They are matched at the start of their second round, but as time goes, Aika started coughing blood and her movements became sluggish until she finally took a clean hit from Kokabiel and dropping to the ground like a meteor creating a crater.

"Aika!" Sona called out for her in worry for the second time today. She tried to catch her fall again by using her magic, but their battle is too fast for her to react and next moment, Aika already laying on the crater, coughing up blood, and trying to stand up but couldn't, 'What to do? What do I do...?' Tears are already threatening to fall from her eyes as she reaches Aika. She noticed that these past few days, all she can remember doing is crying silently so she tried to hold it in. She didn't think that it would be this easy for her to cry as this wasn't the case in the past.

Sona helped Aika stood up while still coughing blood, "What happened? Why did you suddenly start coughing blood?"

"Well... I pushed myself forgetting about the side-effects of that candy..." Aika answered.

"Candy? What candy?"

"It's something Kisuke gave me to forcefully pulls out my potential to fight. And as you might have expected from hearing that, It also damages my body with prolonged use." With Sona's help, they went out of the crater and gathered with the rest.

Koneko is still unconscious while being healed by Asia and being carried by Akeno. The rest are just looking at Aika with differing expressions.

"What? The first time you see someone so cool?" Despite her appearance and her inability to stand alone, Aika was still able to joke around. It's not that she still has confidence, but she already resigned herself to fate. Due to the self-hypnotism, she was able to see life lightly, including her own. Although she still knew the importance of her friends and allies that's why she didn't escape alone.

"Kuh Kuh Kuh. I see you still have the guts to joke around. Do you still have something you haven't shown?" Everyone looked towards the floating figure. Although he's a bit tattered, he still very energetic and they can feel a more intense aura than before. Kokabiel already stopped holding back.

"I'm really surprised that you were able to push me this far. I didn't expect that someone of your caliber would appear here, though it seems that there are limits to what you can do." Truthfully, Kokabiel became a bit fearful of Aika. Although he is one of the strongest in Grigory, his strength doesn't lay on himself and a one on one fight isn't his forte.

"This has gone for too long. Time to end this." Kokabiel then conjured the largest spear of light he ever did in the duration of the battle intending to annihilate them in one shot.

Sona, Akeno and Rias went in front of everyone and used the last bit of there remaining Demonic to create a barrier that will shield all of them from his attacks, '...Is this the end?' Sona thought as she knew that despite their best effort to defend, they won't be able to take that, '...Kisuke...' Sona thought of the guy who gave some 'excitement' to her monotonous life of chasing after her dream despite the short time they have met and ended up tearing up again. She at least wanted to meet him one last time, 'I shouldn't have run away... I should have followed what I want... At least, that way, I wouldn't have to regret my actions until now... I'm a failure of a Devil...'

"Vali, go take Kokabiel now. And don't forget about that Freed. I have a few questions I want to ask him. Make it fast before the host of the Red Dragon Emperor finishes surrendering his whole body to the dragon." Azazel commanded seeing the situation. He's also staring at Issei as he tries to seal the deal with Ddraig but he won't be able to make it in time before Kokabiel blasts them into pieces. He already lost his initiative.

"Understo..." Vali was about to take off but he suddenly stopped in place.

"What's wrong?"

"Someone is coming..."

Out of nowhere, a bolt of lightning suddenly pierced the barrier on the school and it landed behind the group of youngsters. Everyone looked behind to see what's going on and from it, a door made out of wood and transparent paper or a shouji suddenly materialized. From behind it, they can see a very familiar shadow with a bucket hat and large kimono.

Just from this, they knew who had just come in an unbelievable way. Meanwhile, Sona is panicking, 'What is he doing here!?'

The traditional Japanese door opened and the rhythmic sound of wooden sandals hitting the ground was heard all around. And they all saw Kisuke with a grin that didn't reach his shadowed eyes, "Thank goodness. Looks like I'm still not late at the party~. Since I'm already here, let's make it, even wilder~."
