Duel

They left the old school building to have their match on the clearing in the forest. But just as they stepped out, someone came to them, "Ah... Koneko-chan~! There you are!" Aika came running towards the group, "Good afternoon Rias-senpai, Himejima-senpai. I would like to have a talk with Koneko-chan if that's fine with you."

Before Rias could answer, Issei and Asia reacted, "Kiryuu-san?" "Kiryuu? What are you doing here?" Both of them, including Yuuto, don't know about Aika's involvement with the supernatural world because Rias, Akeno and Koneko didn't tell anything about her to them. In their eyes, Aika is only a normal human, and that's also the same for the two exorcists who kept quiet for now.

"Just like I said, I have something to talk about with Koneko-chan," Aika answered Issei's question.

"But we're busy with something... Just come back tomorrow, okay?" Issei tried to persuade her because he doesn't want someone ordinary like Aika to get dragged in this dangerous situation.

"It's fine Issei..." Rias finally said something and faced Aika, "Aika-san, you can come with us. I'd like to hear your input in some things."

"Buchou!?" Issei, Asia, and Yuuto looked at her in shock. Even Irina and Xenovia changed the way they looked at Aika. Based on Rias' words, it seems that this ordinary human has some dealings with the Devil's side and seeing something like that in person for them is an unpleasant affair.

Aika noticed the way the two new people looked at her and became confused, "What's going on?"

"Just follow us for now. It might become interesting for you." Akeno followed up and they started walking towards the clearing where they would have their duel with Aika in tow. Issei, Asia, and Yuuto were, of course, still confused about why would Rias and Akeno allow someone like her see their fight.

Aika leaned on Koneko and asked, "Really... What's going on?"

"A fight." A simple answer came from Koneko. Aika didn't speak any further and just quietly followed. This will be the first time she would see how others fight and would like to compare it with her own experience with Yoruichi and Kisuke's training so she's looking forward to it.

They reached their destination and the four combatants got into positions. Xenovia and Irina simultaneously took off their cloaks and revealed the black tight-fitting bodysuit which reveals their womanly curves, "...Perverts?" Aika couldn't help but comment on their attires.

"Hmmph, how rude... This is the Church's latest battle suit that helps us easily augment our Holy Powers with our bodies." Irina immediately retorted.

"So it's in the same line up as Bikini Armors..." Aika muttered, but the two exorcists didn't know what she meant by 'Bikini Armor' and didn't ask further.

Issei, on the other hand, is trying not to drool while staring at them. He's also trying not to laugh after hearing Aika's words. He's probably the only other person who understood her comment.

Xenovia faced Rias and said, "Before we begin, allow me to confirm. This is a fight over a private matter that needn't concern the Church at large. We won't make anything more off it, and neither will you? Is that correct?"

"Yes." Rias answered, 'Yuuto won't rest easy until this is over after all...'

Getting her answer, both Irina and Xenovia took their stances, "The power of Rias Gremory's peerage, and that of one of our alleged 'seniors'... I shall test both of them."

"Hehehe..." Yuuto is very excited to finally face against someone who wields the legendary sword and couldn't help but laugh creepily.

"...You laugh?"

"I've wanted to destroy them so badly, and now here they are in front of me. I could not be happier." Even though he said he is happy, his face couldn't be any grimmer.

"I heard one of that one of the test subjects from the Holy Sword project escaped, so that was you?" Xenovia's words ended up worsening Yuuto's mood even though she didn't intend to.

'Whoah... This isn't a battle to the death. Let's just make this a casual match! I'm begging you, Kiba...' Issei wished inside her mind.

"Issei Hyoudou-kun..." Irina caught his attention back, "We finally see each other after so long, and it turns out you've gone and became a Devil. I'm shocked!"

Issei scratched his head in embarrassment. After he cleared up his head, he also understood their actions as they are trained by the Church as soldiers. Even Asia had a hard time adjusting to her Devil life despite not having much intervention from the Church itself, "Well... Irina Shidou... I said what I wanted to say about you guys badmouthing Asia, so we really don't have to fight. It's not a big deal."

Irina, however, ignored what he just said, "I was shipped off to England after discovering my attitude for Holy Swords. All I've wanted since then is to be useful in my role as an agent of the Lord. How cruel is fate to turn my childhood friend into a Devil! Perhaps, this is merely another trial from God! I will overcome this too! Once more, I'll allow my faith to lead me down the path of righteousness!" She then proceeds to point the tip of her katana towards Issei, "Now then, Issei-kun! My Excalibur will judge the weight of your sins! Amen!"

Issei is gobsmacked at her monologue, 'Huh!? It seems that she's the type of girl that just can't say no to a fight...'

"Issei! This is no ordinary fight! Take great care not to get hit by those Holy Swords!" A warning came from Rias.

"I don't know what's up with you, but here we go!" Issei raised his left hand, "Boosted Gear! Let's go!" "BOOST!" Transforming his hand into a gauntlet.

"...Longinus." Xenovia muttered after seeing it.

"That's the Boosted Gear? To think we would encounter it like this..." Irina became a bit more serious.

Using this chance, Yuuto dashed towards Xenovia and initiated an attack. Thus, their duel started.

A few seconds after they started, Rias asked Aika who's watching intently, "What do you think?"

"...Honestly... It's underwhelming..." Aika replied after watching for a few more seconds, "Kiba-kun is... too impatient with his movements even though it seems that he can overwhelm his opponent with just techniques. Even if the girl that is swinging a big sword like that is a power fighter, with a clear head like that, she can easily take advantage of his movements.

"Hyoudou-kun, on the other hand, is normal. A normal ruffian with a strengthened body... Even though he can dodge his opponent's attacks, she's clearly holding back. And to top it off, he kept making that creepy face. What is he doing anyway?"

And just after she said that, Issei used the accumulated power of the Boosted Gear to boost his physical abilities and started to retaliate. However, his movements are too creepy for the audience. He kept trying to grab his opponent's chest in the guise of an attack.

Seeing this scene, all of them suddenly remembered one of his techniques. As a member of the female legion, Koneko warned her comrade, "Please watch out. Issei-senpai has a move that lets him tear away the clothes of any girl he touches."

"Koneko-chan!?"

Irina instinctively covered her chest while giving him a fed up stare, "How awful! Oh, Lord! Please save your forgiveness for someone more deserving than this sinful pervert!"

"Hey, Don't look at me like that! With those pitying eyes!" Issei still has some embarrassment left in him, so he felt awkward being looked like that.

Asia who is watching silently, suddenly shouted from behind, "Issei-san! If you crave for naked female flesh so much, please just ask me!"

"How can you tell me something so important at a time like this?"

Even Xenovia and Yuuto temporarily stopped their clash due to this, "I see. So he's truly a personification of lust. From the start, he did strike me as a particularly lewd Devil."

"I'm sorry about him..."

"Oi, Kiba! Don't apologize for me!"

Yuuto then conjured two demonic swords with fire and ice attribute and resumed attacking. However, with just a swing of Xenovia's Excalibur Destruction, it destroyed both of the swords. And it didn't stop with just that, as after it hit the ground, it created an explosion which gouges the ground, generating a large crater.

'No way... Damage like that just from a light swing? Kiba... Destroying those swords seems harder than you initially thought...'

"Don't look away, Issei-kun. I think we'll be done over here soon too." Irina swung her katana at Issei but the pervert easily dodged it thanks to her strengthened body.

With a glint in his eyes, Issei started moving around Irina at a faster pace, "Time to strip you down. Sorry~."
