"Now Sera, Akeno…let us dance the merry jig of death with Beelzebub."

Beelzebub Shalba, Prince of Flies, Master of the House of Beelzebub and his own legacy was descended from the First Beelzebub; swore. Those insignificant gnats of Highborn Devils and there equally if not worse subordinates of a peerage had taxed him slightly. He'd been taxed magically than he thought he should have been; then the imposter Leviathan appeared with her own servant. Did they really think one servant would be enough to contend with him?

His internal thoughts nearly cost him as an armoured claw shaped distinctively like a werewolf claw nearly sundered his armour. "A mere lycanthrope…I've killed…" Shalba began only for the nude servant to summon a sword, that seemed rather familiar to him; he'd seen it before but where?

He unsheathed his sword to deflect the strike only for his sword to shatter into a thousand pieces "Fragarach! You, who, wields The Answerer!"

Harry smirked "Aye, it is the Answerer. And yes you'll answer, for the bell tolls on you, Beelzebub Shalba. The bell tolls." With that Harry began to demonstrate his skills.

Shalba was a powerful Devil and classed as a Technical Devil if he chose to participate in Rating Games. Harry was a power-type, normally technical beat power; but Shalba had deliberately under-estimated Harry due to him appearing on his own; Harry's first strike had caught Beelzebub off guard and with the Elder Devil off guard, Harry just needed to keep his momentum going.

And keep it going, he did. Shalba summoned a sword along with a hoard of Wasps. Harry, pulsed a blast of magic out of his body in the vaguest outline of himself, the pulse of magic destroyed the summoned Wasps; the sword however absorbed the magic. Shalba smirked, and brought the sword to bear and unleashed the freshly siphoned magical energy, fused with a healthy bit of Fire Magic.

Everyone screamed as a ten foot tall and five foot wide literal tidal wave of flame, cascaded onto Harry. The only four who seemed relatively unconcerned were Akeno, Serafall, Neville and Hermione "Everyone calm down, that's only made Harry...slightly mad." Neville barked, as he readied himself to unleash some of the darker spells, he'd read from Harry's books.

True to Neville's words the fire died down, revealing Harry in his dragon-armour. "Very good Beelzebub." Harry mocked "That…hurt. Hurt more than Phenex in anyway." As he was goading Beelzebub, the Elder Devil, was slowly losing his composure.

"You...insignificant recent conversion! How dare you demonstrate or even insinuate that mere conversions are better than pureblooded devils!" Shalba roared as he pulled on more of the magics inherent to the Beelzebub Magic.

Harry grinned "This is sounding like performance issues; there's a brilliant mortal medication by the name of Viagra. It'll help you keep it up. Besides devils have only just started being able to reproduce…shit shock horror." Harry grunted, blood trickled out of his mouth as Diadora Astorath took the advantage to drive a dagger into Harry's back right through one of the few thin cracks in the armour where the plates didn't fuse correctly.

Harry's right arm, lashed out. Catching the Astorath Heir in the throat, Harry felt three magical seals on the Astorath surge to life "You took anothers blessing? Wrong move."

"Is it not wrong to fight for your belief?"

"Nope. It is when it has been stated that it's actually aiding and abetting terrorist sects intent on throwing Devilkind back into a bloody civil war. I also look down on the Old Satan Faction for joining another's scheme and causing world wide chaos." Serafall chipped in, wearing this time an appropriate battlegarb "I get enough chaos from my latest acquisition."

"Harry doesn't count, Serafall." Hermione chimed in recieving what could only be described as an emoji sad face in return from the Foreign Affairs Mao.

"She is right lady Leviathan…" Akeno chirped in unleashing a lightning bolt at Harry and hitting Diadora Astorath as well.

Shalba activated his own serpent blessing and Serafall smoothly intercepted. The ongoing brawl slash invasion had petered out, now the main combative hotspot appeared to be here. Harry focused and the knife that was buried underneath his ribs wriggled and shot free skittering across the floor and vanished as McGregor arrived shortly followed by the rest of Sirzechs Peerage, including the man himself and his wife and in a similar circle Beelzebub Ajuka appeared on his own.

"Shalba Beelzebub, it is a pleasure and a pain to see you again." Sirzechs murmured, pencil thin grin on his face.

"Sirzechs." What happened next for Harry happened almost far too quickly.

It took six seconds, six seconds, for Harry to effortlessly decapitate and de-limb the Astorath Heir and in that time Sirzechs effortlessly ripped Shalba Beelzebub apart; with what looked like the Power of Destruction.

"McGregor...what the fuck was that? That looked like the Power of Destruction; but nothing like I'm familiar with or even able to replicate."

Sirzechs turned to Harry "You realise that you stating that puts an even bigger target on your head."

"Only means more corpses to add to my tally; hopefully after I've killed enough entities wanting my head perhaps people will get the gist and leave me alone. All I wanted was to lie low; now here I am the homicidal janitor of the Gremory Sitri holdings in Kuoh."

"A homicidal janitor with trollish ideas and an even worse temper." Rias retorted "I still don't see how knocking out my pawn helps matters."

"Have you ever stopped to think about why I say what I say? I'm surprised 'Mione and Neville haven't informed you." Harry drawled as he dropped into a crouch.

It was Sona whose eyes widened, she strode forwards and was about to stitch Harry's stabwound closed when she saw it heal "You, give us awful ideas because you want us to think everything over?"

"Sona, you finally get it…When did you work it out?" The Heiress sighed "Not as soon as I would have liked; I thought it was you being you, in order to maximise the causality of chaos and the chance for you to dress up and look utterly ridiculous."

Harry nodded "Fair, you've got me...partially."

Sona nodded "Then there was the fact of your face. Especially when Kokabiel intervened and when we had the exorcists here; your face had the distinctive look of 'Why does this happen to me'. I've concluded you give us really, really bad ideas mainly because we end up in scenarios that require equally bad ideas to extricate ourselves."

Harry nodded "There you have it. Always plan for the worst...no-one ever understands why I plan for the worst but there you have it. Plan for the worst and moderate plans are revealed in your planning; by the way…have I actually been paid?"

Rias's eyebrows rose "You want to be paid?"

"Uh…yeah. I found you a group of individuals just as gifted as I am if not more so, I've supplied you with knowledge, books, bad ideas, patched your limbs, given you prescribed medications."

"I'm not sure alcohol counts…" Rias commented blandly.

"I've intervened on several sis-con issues, gave Rias a fighting chance to guide her life instead of being treated like a brood-mare. Or do you really want me to have to go to Crowley and get him to issue Houses Sitri and Gremory and Sitri Sona and Gremory Rias with papers?"

This was too much for Sirzechs, Ajuka and Serafall they began giggling at the thought of a devil hiring a devil to sue other devils "Considering your track record, Mr. Potter…Contact my cousin and I am 80% certain if you, my parents, Sona-chans parents, myself, Serafall and Ajuka all sit down and talk we can come to an agreement that suits everyone." Sirzechs instructed.

Harry nodded "Now, is everything dealt with? I could really do with beer and some heart-attack takeout."

"Is that your solution to everything?"

"Most...I mean beer and takeout is much better than mass murder and homicide."

That killed the conversation, Serafall grabbed Harry "I need you to assist in some paperwork. Akeno-chan, you'll get him back at somepoint within twenty-four hours."

Harry could only groan. "Consider this a promotion, you're now my homicidal paperwork killer. You'll help me kill my paperwork so I can do my hobbies; how's your Gaelic accent?"
