I understand if some of you don't like the whole issei replacement thing, but my version of this is to make it more suitable for my storyline. I'm not trying to make it like an OP Issei I'm more looking towards a different lore route, exploring more of the century old war and how he got to where he was now. Keep following along and I promise you I'll make it worth your time. I know it's a harem, but it ain't every girl there. It's specifics that I'll eventually show once the story progresses

Anyway, let's do this…

After a complete mess of romance, revelations, shock, and obscurity, The 4 individuals went to Shinos house to discuss their current situation; becoming a member of Rias Gremory's Household. However, since he was an archangel and his powers were still shrouded in mystery, it was unclear what the outcome would be.

At his house, it was big, but had just enough space to hold guests if necessary. He had cooked some chicken tonkatsu for everyone, but unfortunately, it almost skimmed his chicken supply.

"Okay so let me get this straight. You want me to join your peerage and see what power level I am?" Shino asked, completely appalled by her request.

Rias took a bite of her meal before continuing. "Yes, that's correct. Regardless of whether we would date or not, I have planned to ask you for quite some time."

"But you would've had no idea if I was an angel or not. Did you plan on resurrecting me or something?" He asked as he continued to eat his meal. Raynere took the liberty of doing the dishes because Akeno was still giving her death glares, yet Rias eying her must have stopped it for a bit.

"Well, if we had done the oath your form would've most likely revealed itself to me. That is how it works after all." She said as she took out a chess piece. "This should explain your power level once you hold it."

"Now, are you sure you want me to do this?" He replied once more as he held out his hand. "If we do this, then word will spread. I'm fine with your brother knowing I'm back, but the others might not take it too kindly."

Rias placed the chess piece in his hand before turning her attention towards him with a confused look. "Did you commit any crimes during your known times?"

"No. It's just I was uh..well known to the least. Especially when the whole great war thing happened…" He finished that last part silently as the chess piece started to violently turn into a black flame, forming itself from a pawn to a king in no time flat.

Rias and Akeno were in shock when they saw his piece mutate into a king. "That's impossible. You're on par with a high ranking Devil! You can't be anything else but a king!"

"Two kings in one set? Would that go against the rules?" Akeno asked.

"I'm sure my brother can answer that when we get there." She answered as she took the piece, which then mutated into a union piece. It was a black and crimson red king piece. "Wow. Looks like it already accepted the rank. You're my new king. You could be my second in command I guess."

"Well as a boyfriend, that's my job in the first place. As a second king, this should be interesting." Shino said as he got up and grabbed Rias and Akeno's plate, who had just finished their meals as well. "Should I do some vow or oath?"

"That won't be necessary. You've already become my betrothed." Rias said nonchalantly, yet Akeno had a concerned look in her eyes.

As Shino left the room to enter the kitchen, Akeno moved closer towards her king. "President, you have to be aware of the engagement too. What if he finds out?"

"Akeno, he could be the one to fix it! I've fallen for him ever since we were in middle school, I wouldn't do this as leverage. Even if I didn't know that he was an angel, he's someone I care about more than that asshole." Rias said bluntly towards Akeno. Rias held some hope into herself for that, but she was right. What if he found out? "I should probably let my brother know he's well and he's the second king in my peerage."

Rias took out her phone to text her brother about it, who immediately responded with an alarming emoji and said "OMW ASAP."

"That was fast! Is he seriously coming here?!" Rias said, alarmed at her brother's reaction. Suddenly, two portals, one purple and one dark crimson red appeared in front of her, to which Sirzechs and surprisingly, Serafall Leviathan appeared as well, dressed in a magic girl suit, while her older brother looked like he just got his pajamas on, which was very unlike the devil king.

"Where is he?! Is he really here?!" Sera asked as she looked frantically around the room. Her brother immediately rushed towards her and started shaking her like crazy.

"What did he tell you?! Was he hiding from me on purpose?! How did he become your age?!" It was like he was interrogating here, to which Rias shoved her brother off of her.

"Calm down brother! He didn't mention anything else! He said he was fine with you knowing, but why is lady leviathan here?!" She was completely taken aback by her brother's behavior.

Just then, Shino walked into the room with some brownies he made, only to stop dead in his tracks as the three individuals suddenly came into eye contact with one another. "Z?! SERA?!"

"Azrael you're alive!" Serafall shouted as she bounced onto him, almost causing him to drop the brownies. Luckily, Raynere was next to him and helped grab the other plates and set them on the table. "Where have you been?! What happened to you?!"

"Yeah, what is the meaning of this betrayal?!" Sirzechs asked as he helped Shino up and pried Sera off of him, "You said you'd be alright after the whole war thing happened."

"I was. It's a long story I'd rather not discuss right now." He said as he stared towards Rias, who chuckled nervously. "Um, don't get mad, but I'm dating your sister."

"WHAT?!" Both devil kings shouted as Serafall was equally confused.

"Big brother, I've liked him since middle school. He might be my chance at getting out of the-" Rias was about to continue but Serafall stopped her.

"You were alive when Rias was a child?! Did you die or something?! Do you know how worried sick I was?! It was bad enough that you left. I was just about to tell you how I felt, but you left right after the whole bael incident!" Sera seemed to have a lot on her mind. He was just as shocked to hear this as Sirzech and the others were.

"Good lord, I must be dreaming." Shino said as he rubbed his head checking for wounds. There's no way Serafall liked him too. He didn't know about Raynere because he saw her as a little sister sort of thing, but in his second life Rias was the one he started to care for, but in his previous life, there was someone else he had truly cared for…

"Okay, enough. Let's get back to the task at hand." Rias suggested, Now visibly frustrated by this new discovery. A devil king is in love with her betrothed. "Brother, he has the power level matching a high class devil. The piece mutated into a king once it touched him. Is he able to become a member of my peerage and be king?"

"If it's a mutation piece then it should be feasible, and considering it was limited to calling him a high class devil, that would be an understatement…" Sirzechs admitted nervously, "But that's besides the point. Serafall, do you accept him as a second king towards my sister's peerage?"

"Yes I support it 100 percent." She said almost immediately. "On one condition. You and I must hang out again. I miss your presence from watching me on set!"

"That's fine. I can do that." He replied sincerely, causing a warm smile to escape her lips.

"This is one of the most relieving moments of my lifetime so far." Sirzechs admitted, "Once we were enemies, Now we are allies once again. I'm glad to see you're alive and well, Azrael."

"Please, call me Shino. If any word gets out about me being alive half of those old farts will cause an uproar. No telling what Azazels gonna say when Raynere brings the news.." Shino requested as Raynere nodded in agreement. "Besides, Father had to do a LOT of work to make sure the others didn't leak out anything to the other factions."

"Father?! You mean…GOD?" Akeno asked, appalled by his words. Shino nodded his head in agreement before Akeno sighed. She had learned a lot today.

"Well, I'll be off to tell him Shino. I'll keep it a secret to the others, but Mittlet will be the first to know." Raynere said jokingly as she used her own portal to travel to the grigori HQ.

As she left, Sirzechs turned his attention towards his sister. "Rias, I'm happy for you. However, know that the others will be asking questions. Especially Serafalls sister, Sona."

"What's wrong with my sister knowing?!" Sera asked defensively. She got very sensitive with her sister. Besides Shino, she loves her just as much.

"It's because Sona is the student council president. You know that she's going to be furious when she finds out I'm an angel working for Rias." Shino answered as he pointed towards his skateboard. "She already hates me for skating on school grounds. She almost had Tsubaki beat the crap out of me!"

"Well…I'm sure I can explain things and maybe she'll leave you alone!" Serafall suggested, to which Sirzechs and Shino both looked at each other before shrugging their shoulders. Can't be helped that she's very protective of her sister.

"Well, it's getting late. Serafall, we should leave these two alone and go back to our duties. I'm sure Grayfia will be dying to hear the news." Sirzechs said, stretching his arms indicating his sleepiness.

"If you insist." Serfall said sadly as she looked towards Shino once more. "Be ready. One day, I'll tell you how I feel. And I hope you can accept me."

Shino smiled and winked, indicating he would answer when the time came. After that, the two devil kings took their leave through their own respective portals, leaving only Akeno and Rias in the room.

"Okay Akeno, I'm staying with Shino tonight so there won't be any need to stay with you. I'll see you tomorrow okay?" She requested from her queen, to which Akeno bowed and waved at Shino before heading out. "Well, now that you're my new king, I suggest we start living together as one. We are both equals, and it's only fair considering that we are both in love."

"Dad wouldn't want me to do this. I ain't supposed to sleep with a woman unless we're in wedlock." Shino reminded her of his moral beliefs. He was an angel after all. Yet, Father did always tell him the judgemental thing was only through blatant sin, and Shino was no evil. "I guess this will be okay. But if I get a phone call, I'm blaming you."

Rias laughed as she made her way towards his room and Shino followed suit. Seemed the archangel of death had been reacquainted with old friends, and now a member of the gremory household. But what other misadventures will this angel find? Angels and Devils working together? Who would've thought…
