Serafall is very curious about what Kisuke is trying to do, but she didn't ask about it as she's about to see it the same. With a have of her 'magical' wand, multiple dark blue magic circles appeared around 'Kokabiel', "Magical Icicle Lance~✰!"

From the magic circles, large lances of ice shoot out and pierced 'Kokabiel', "KAAHHH!!!" Releasing a shrill scream, he tried to shake off the protruding ice but the lances didn't just pierce him but also started to spread frost all over his body.

"This... This is the power of a Devil King?" Xenovia muttered under her breath. She's feeling bitter after seeing the power of her supposed enemy, 'No human can go against that...' She thought and already forgot that Kisuke is a human. Well, in the first place, she hasn't considered Kisuke as a human.

The young Devils are also in awe at her display of magic... except for Issei. He has been staring at the guy with a white armor, 'Ddraig... Could he be...'

'Yes. That's the white bastard.' He answered his question, 'But now is not the time to watch him. Be sure to take a closer look at what your friend is capable of. I have a feeling that it'll be something amazing.'

Issei breath out to calm his nerves. He already stopped resisting and watch the battle unfold, 'One day... I'll be also standing beside them... But to do that, I have to train more.' Ambition started to gush in his heart.

'This guy finally has more motivation aside from being a Harem King. I look forward to the future.' Ddraig thought to himself, 'Albion... It seems like we'll have another epic battle in the future.'

Even with Serafall's magic, 'Kokabiel' still was able to recover and started beaming around again, further destroying the already unfamiliar place.

This time, Vali came in and flew around the deformed baby with amazing speed. Each time he approaches 'Kokabiel', he'll be removing a sizable amount of meat off him making the baby rampage more. Hundreds of tentacles even started to sprout all over his body and acted like a giant whip that destroys everything it touches.

"Hmmm... This is bad... I underestimated its vitality. Even if I try erasing it along with this town, I doubt I could kill it... Ki-tan, is your plan still feasible?" Serafall kept casting her magic and stopped calling out 'magical' names for it as the situation is more serious than she thought, 'Should I switch with Sirzechs-chan?'

Vali is also furrowing his brows inside his armor. He loves battles but he doesn't like this one-sided beating up of an undying enemy. It has no thrill to offer or whatsoever. He also kept using his Divine Dividing, but it only has a minimal effect against 'Kokabiel' and Vali is pretty sure that 'Kokabiel' is also recovering the energy reserves he has lost, 'But how? The mana in the surroundings isn't enough to feed this guy...'

Kisuke didn't answer Serafall as he only kept staring at 'Kokabiel', 'I can't blindly use Kidou... If I don't hit the right spots then it'll only regenerate again. But I can't properly see from here... To see its insides... I guess cutting it up is the best choice I have~.'

Inspecting 'Kokabiel' for a few more seconds, Kisuke finally spoke, "I want to see what's inside of it first~!"

"Huh?" Serafall temporarily stopped casting magic and looked at Kisuke. Even Vali stopped in his tracks trying to understand his intentions. Off to the side, Yoruichi and Aika did a facepalm, "Kisuke! It's not the time for that!" Yoruichi shouted at him.

"No no no, my dear Yoruichi. This is the right time for that!" Kisuke retorted.

"Uhmm... Look from inside? Do you want me to drill a hole for you to enter its body?" Serafall asked, "But I advise you against it... Getting inside that thing won't be a pleasant affair and you might get trapped if that thing started healing."

"Nah... I don't need it. For now, please step aside... Including the guy in a gaudy white armor." Kisuke replied.

Vali wanted to say something for calling him that way but stopped himself when he noticed his aura shooting up again. Serafall also stepped aside and curiously looked at Kisuke.

Raising Benihime, the wind started to circulate around him and he has to hold his hat to keep it from flying off. Kisuke then released the majority of his Reiatsu-Ki which unintentionally manifested in a form of pressure and was felt by all of those who are around.

The young Devils instantly dropped down to their knees with pale faces and had to use their hands to keep them from dropping to the ground. Yoruichi has to use her own Reiatsu-Ki to offset Kisuke's pressure so that the young Devils and the single exorcist could breath again, "Be careful, will ya."

"Ah... Sorry, I got too into it." Kisuke just chuckled and kept on channeling his Reiatsu-Ki to Benihime.

Serafall's smiling face entirely disappeared and only stared at Kisuke with a very serious expression that doesn't match her personality, 'We have been overlooking a guy like him?... I failed as the leader of Foreign Affairs...'

Vali became apprehensive of Kisuke, but his battle intent also soared up that he has to greatly control himself from suddenly attacking him. Although the smile in his face couldn't disappear.

A crimson aura started spilling from Benihime and when it reached a certain level, Kisuke brought Benihime down in a swing, "Nake! Benihime!"

A crimson wave manifested, accompanied by a high pitched whistling sound that rang through everyone's ear making the command 'Scream!' very suiting.

The crimson wave instantly arrives on Kokabiel and it went through him, splitting his 100-meter tall body in half, "KAAAHHH!!!"

The wave kept traveling until it almost hit the barrier, now 3 kilometers away. Once it disappeared, it only left a divided baby and a straight crevice with an unknown depth.

"N-No way..." Xenovia and Yuuto muttered. Both of them are sword user so when Kisuke showed them how he used his sword, they blanked out.

Serafall's mouth is twitching as she looks at the result, 'That's a lot stronger than I thought... I can't gauge its full power just from the destruction it brought to the landscape..'

Vali only kept quiet. It's unknown what he's thinking.

Kisuke ignored their reactions and only stared at 'Kokabiel's' inside. He also started healing himself so his time of observing is only limited, 'There... there... there... and there... Good, I can deal with this thing now.'

Kisuke didn't act immediately and started to modify the Kidou he's going to use in his mind. The moment 'Kokabiel' healed completely, Kisuke also finish his slight modification.

Although 'Kokabiel' completely regenerated, he's a lot less energetic and he couldn't even properly use his beams of light but Kisuke knew that this is only temporary.

"Levia-tan." Kisuke called out to Magical Girl that didn't stop staring at him, "Y-Yes?"

"Could you please stop its movements for a bit?"

"O-Okay." Serafall couldn't understand Kisuke. He just did something unbelievable for a human with unknown 'Sacred Gear' and still kept a nonchalant expression with a Devil King who's eyeing him with vigilance. She didn't notice that she already fell in Kisuke's pace.

Casting the first magic she did when she arrived, Serafall froze half of 'Kokabiel's' body. After doing so, she looked back to Kisuke who already pointed his index finger upwards and started chanting.

"The crest of turbidity, seeping out. An insolent vessel of madness. Boiling up, denying, numbness, blinking, obstructing slumber. The steel princess who creeps. The mud doll, ever disintegrating. Unite! Oppose! Filling the earth, know your own impotence! Hadou no 90, Kurohitsugi(Black Coffin)!"
