I own nothing
This is my first fic in the Highschool DxD world.

IXX: "I thought Harry was bad."

Rias and Hermione had their heads bent over a few law books amongst Devilkind trying to find a suitable reparation for the wrongdoing on the behalf of Gremory to Astorath.

"Don't see why you can't contract Leviathan and get her to lend you Harry." Akeno said grinning widely as Rias flushed.

"Akeno, just because you're involved with Serafall's latest piece doesn't make you an advocate for dealing with the insanity that Serafall would have us do."

Akeno giggled "No, no, no…It is, I remember the wording of Serafall's instructions to my lover."

Hermione cocked her head "Serafall was the one dressed as a Sailor Moon?"

Rias nodded and Hermione paled "Akeno, that…is a horrible idea. I thought Harry was bad at making plans. But that is horrible."

"What's a horrible plan?" Koneko asked as she arrived looking like a Counter-Guardian version of Rin Tohsaka that had been given Avalon instead of Shiro.

"Akeno wants to endanger Sona, so Harry will arrive in fiery crash/dynamic entry, then proceed to offend and hit-on everyone and everything before opening a can 'this is going to explode' on everyone." Hermione explained.

"In other words, Harry being Harry…That's a bad idea."

"Considering Harry has now discovered Akeno actually likes him and he likes her…" Hermione stated as Neville entered ahead of Sona's peerage; he was looking rather ragged.

"I…found Harry. He was eating Sona's fridge out of existence. Genshirou had passed out but was getting up out of muscle memory." The well-built wizard said as he adjusted his shirt.

"Is that a hickey or a bruise?" Seamus asked, the Irish wizard had just run afoul of Xenovia Quarta a few days earlier. However, the Irish Pyromaniac and Illusionist and the newest Knight of Gremory, both found a common ground in the Church. Xenovia being strait laced as written, Seamus the laid-back drifter. In everyone's opinion once Xenovia got her own peerage; Seamus was jumping ship.

Rias looked up "Seamus, do you have any sensible or logical approaches that can be used to bring the Heir of Astaroth to the table? He has taken two of my Peerage; my friends and servants."

Seamus paused "I'm guessing the scope of 'contact Harry', 'contract with and for Harry' and anything that risks the Heiress of Sitri is off the table?"

Sona entered "What's this about endangering myself?"

"Some impertinent little shit-stain has abducted one of Rias's chess pieces. The naïve bishop and the time-stopping transvestite."

"In other words, both Bishops, Mr. Finnegan, Rias's casters and support."

Seamus nodded "Seams so. I was out of my skull and only just found out."

Rias and Sona looked at the Irishman "What is it with you British wand-wavers and alcohol?"

"You watch Harry James Potter, pull the Ministry of Magic to the ground and tell us to wipe our own arses. We had eight months of incompetency then most of us dropped out of Hogwarts; completed our education through tutors, and tried to do a hostile take-over. We called it 'Lord of the Flies', the only shame was the money we were promised dried up. Soon enough we were back to square one; we were planning to leave and then 'Hurricane Hazard' waltzed back in. So yeah, you need to drink."

Rias and Sona sighed "Rias, what have your additional help been suggesting?"

"We've been suggesting throwing you at the Heir of Astaroth thus provoking Leviathan's latest acquisition into turning Astaroth Diodora into well a deceased version of himself."

Sona sighed "No thanks. Harry would then take great satisfaction and even greater pleasure in tormenting my peerage and myself; more than he normally does."

Rias grinned "I share your sympathies; I am sorry but also not sorry for introducing Harry Potter and his family to the Underworld."

Sona giggled slightly "You apologise for Harry and his sect of the Supernatural's shortcomings; drastic as they might be and Lord Potters casual affinity for trollish tendencies and mass disasters…My, sister did right getting Potter sworn to her; it keeps his unpredictability where everyone sees it."

Seamus smirked "Sitri, you realise that Leviathan is rather…absentminded. Harry's no dog, more of a cat; goes where he wants, when he wants. He's been tasked to help you, thus beats up your peerage; Himejima controls his nightlife that's why he brings his migraines to us."

The assembling members of the Peerages and the contracted wizard/mage hybrids all glared at Seamus. "How does any of this assist us in getting my two bishops?"

Seamus shrugged "Challenge him to a fight…Or rating game. Most logical."

"I have no full peerage, my tactics relied on my bishops." Rias retorted.

"Improvise…Now, I'm going to find Harry and have a bit of a drink with him."

(Harry and Serafall)

Thankfully the Leviathans and Sitri's had holdings in Germany. The pair materialised in cosy penthouse suite "Shall we?"

Harry smirked "We shall indeed" with that chaos was introduced into Germany. As Serafall linked arms with Harry, his phone went off.

"Seamus."
"Oh…oh dear… Thank you for informing me. Currently I'm in Germany; I'm…on business. So go have fun, and please hit that prick Astorath for me…I'm not picking up this mess, it's not even my fault."

Serafall giggled, she leaned closer to her new minion. Her hearing allowed her to make out the response "Sona and Rias are calling you a liar. They're blaming you for Genshirou Saji and Issei for failing to meet their clients."

"That's not me. I trained them leaving them plenty of time to get ready before meeting their clients. Not my fault, not my problem. Seamus, you're a living Sacred Gear, the Flame Engine it's common as fuck; it's the gear that gives 'Humanity Fuck-Yeah' elemental aligned magics. Yes the Avatar is possible but no it doesn't gain awesome special stances." Harry replied, only idly realising just now how much he already suspected about his classmates. "Now, if you want my advice; challenge Astaroth, troll his ass relentlessly. None of you need me to troll, I only make it easy. See you later, I have business contract to fulfil."

With that he hung up "Is that all I am to you?" Serafall pouted.

Harry's face split into a grin "I am whatever I need to be, to get out of your…interesting, side-project and minion or no." He could feel the raw power of the Mao next to him. As ominously as it came, it quickly vanished.

"I know, I'm sorry. I panicked; I could see that you were regenerating but you looked more like you'd be dead before your body could heal. Ajuka, examined you when you were unconscious, the wanded community's ability to heal is reliant on one's magical reserves and a few other things. In short, you're not immortal, nor are you immune to injuries that would definitely cause devils to retreat…you're hard to kill and extremely so. The 'Deathly Hallows' gives your soul and spirit more magic and resistance to death…a stop gap. Doctor Strange movie, we watched it one evening."

Harry nodded "The defib…I see."

Serafall suddenly grabbed Harry's arm "Come! We have Germany to drink and eat through!"

Harry didn't know just how bad the hangover was going to be, this time.

(Team Rias)

Diodora Astaroth had answered the challenge of the Rating Game. Rias assembled her peerage and her pact magicians downed their ghastly looking potions; all of which had successfully been decoded from the poisons, Harry brewed.

Rias shook her head as the portal to the Rating Game opened, she really needed to talk to Harry; she needed to talk to Harry about a lot of things about Kuoh and not upsetting the status quo.

"Let's go and get Gasper and Asia." Rias declared. Completely unaware of what was about to unfold.
