Here is the start to the Treaty/Gasper arc and it's a long one.
This arc will deal with a lot of Fallen Angels stuff so chapters should be longer.

For some reason, today's club activity is swimming in the school pool. I do not know why but I feel like i'll be bombarded by obnoxious swimsuits. The day gets worse because Asahi is here instead of Raynare, Raynare is having to work today for some reason so Asahi is here instead.

Asahi was wearing a full yellow wetsuit with goggles and a snorkel, why he was wearing that at a school pool is more than beyond me. Kiba took his looks too far and wore a pair of speedos. Thankfully Issei wore swimming trunks. I wore silver shorts but special ones with a hole in for my tail.

The first two to come out from the girl's side was Rias and Akeno, and true to my suspicions their swimsuits were very nearly pointless but much better than I had expected. As the other three boys were already in the pool, both Rias and Akeno came over to me.

"What do you think Gin-kun?"

I lazily looked up towards Rias as she said it and I swear she took a sort of pose to try and flaunt off her body, im not too sure.

"More conservative than I had expected."

Rias looked pretty dejected by my comment, she must think I see her as an exhibitionist.

"Ara Ara, what about me Gin-kun?"

Akeno asking me this brought a good idea to my head, whether it was her intention or not I don't know but it gave me an idea all the same.

I turned my gaze towards Akeno and looked her up and down while faking a lusting gaze.

"Good, really good. Just makes me wanna pounce you."

That line did well to irritate Rias but I was able to make it go even further when I heard the changing room door open once again. I turned to see Asia running towards the pool in the school swimming suit but what caught my attention was Koneko who was nervously making her way towards us. I nervously gulped as I looked at her and started to feel blood trickling down from my nose.

It was the epitome of cuteness, Real Moe. Like Asia, Koneko was also wearing the school swimsuit which thanks to her small physique was able to amplify the attraction of a loli. Her nervousness, slight embarrassment shown by a small blush on her face which she turned to try and hide from me. The white swimming cap amplified it further.

I was shaking from anticipation causing the blood to trickle down faster while becoming noticeable.

"Umm … Gi-Gin-kun, could you … teach me to swim?"

The blush coupled with cute turn of her head completely frazzled me, all I could do was stare as blood started to gush from my nose.

I went to speak but couldn't get anything out as my mouth just hung open. Koneko was right in my strike zone but what she was wearing now was right out of the park. The look alone caused blood to rush to one place. I was broken and the blood just kept coming, I had enough composure still there to slowly bring my hand to my nose and pinch it shut.

All three of them stood there in wait as I slowly came out of my daze.

"I can certainly do that."

…

I spent a whole hour teaching Koneko how to swim, it was more fun than I had expected or should I say it was more fun than it was meant to be. Holding onto her soft, pale white hands as she started to kick through the water, it's too good for words. The way she tilted her head for air as she started to try and swim by herself was also cute. Thinking about it, I feel like Issei has rubbed off on me and not in a good way although it can help me show my affection. Koneko did seem happy when she saw my nose bleeding.

I left the pool first though as I felt a presence I hadn't felt for a few years. Once I had got there I saw who had owned the presence and it was the person I had thought it was.

"Yo Vali."

"Been a while, Silver Moon."

The person before me was Vali Lucifer, true descendant to the original Lucifer. Like me, he had silver hair and a sacred gear although his was a Longinus compared to my unknown. Vali was this generations Hakuryuukou and Issei's rival.

"Here to kill the Sekiryuutei?"

"No, I wanted to talk to you and give you what you wanted."

"You mean the jewel?"

"That is what you wanted right?"

Not really sure I have a need for it but would it actually work is the thing in question. I'd probably lose quite a few years doing so but at least when I gain my second tail it wouldn't matter any more. With God gone, I can even make it better.

"Yeah, of course. Who wouldn't want a dragon as support?"

Vali smirked before throwing me a blue jewel which was larger than my hand. As soon as I caught it I could feel it's energy pulsing through it, it was vast and mysterious.

"How is the Sekiryuutei, Silver Moon?"

"Weak and Perverted. Threaten to use your powers on breasts and you might get a good fight."

"Are you serious?"

I held a wry smile as I slowly nodded. Vali was disappointed by this, anyone would be. Issei is a truly strange opponent. He is a fearful opponent for most women but a weakling against anyone else. As long as you remember that Ddraig is there and his abilities then you should be fine fighting the idiot. I just can't believe he is putting a 'Heavenly Dragons' power to a perverted use. Ddraig must be sulking.

"Wanna hear what his special move is?"

"Not really but you are going to tell me anyway."

"That's correct. Dress Break, an ability that strips an opponent he touches. It only works on women."

A deep and disappointed sigh comes from Vali's mouth, I could even sense Albion being a bit shaken at the use of his eternal rival's power.

"How is the welsh dragon taking this?"

"I'm not too sure, he isn't fully awake yet. The Sekiryuutei has only got a forced balance breaker that was achieved by sacrificing his arm, only lasts for ten seconds too."

"He is a weak host. Azazel did a background check for me, the weakest host in history as i'm the strongest host in history. A bit unfair don't you think?"

"Who cares? You could go for the record, I mean Albion has never had a possessor that's beaten Ddraig twice but Ddraig has. Why not do it and go for three?"

"I would love too but there is that treaty coming up."

"Yeah, there is that. I'm sure you'll find a way around that, you probably already have."

Vali then stared into my eyes confirming my suspicions, he was the one that told that Cao Cao descendant about me. I don't know anyone else who would of.

"And if I have?"

"Then take the devils first, Member of Khaos."

"You came to that already? Well, it's not like I care that you know."

"Not that hard to figure out when you know the people I do."

I saw Vali peer off behind and smirked before waving to me and walking off. When I turned around to see who he saw, I saw Rias and everyone else along with both Sirzechs and Grayfia but no Asahi, he was swapped for Xenovia, when was she here and when did she become a devil. They all just stared at me and the blue jewel in hand, I looked to the jewel myself before sending it to my dimension pocket.

"Who was that Gin-kun?"

"Where is Asacchi?"

I was at a stalemate with Sirzechs. By asking about Asahi, it showed that I don't particularly want to answer him but I will with something in return. Unluckily for Sirzechs, even then I won't give the full story.

"Amaterasu-san has returned to go to work, he mentioned something about getting what he came for."

Rias answered my question making me feel a little sceptical. What could of Asahi came for?

"That was a buddy from Grigori, i'm sure you'll see him again soon."

"Then what about the jewel?"

I raised a single eyebrow at him before talking.

"You sure are a nosy Maou, aren't ya. It's something he promised to give me once I hit my version of Balance Breaker."

Every single one of them looked at me sceptically, to which I just shrugged off.

"Anyway, is Lucifer here just so he can see his sister at school or is he here to check out the place for the meeting? More than likely both. To be honest, I don't really care. I'll hear it all off of the Governor's end."

As I start to turn round to leave, I was stopped by my phone suddenly ringing. I quickly took it out and it was a number I hadn't seen before, despite that I answered it.

"Who is it?"

"Is that you Silver Moon?"

"Barakiel?!"

I shouted out surprised as I held the phone next to my ear. I quickly turned my head to the side and saw the unhappy expression on Akeno's face, I continued to look at her as I spoke again in a now quieter voice.

"It's been a while Barakiel, are you still wanting to marry me to your daughter?"

Both Akeno's and Rias' face widened when I mentioned it.

"Yes, I am and always have been. You were a good student when I taught all those recruits basic fighting. Even though you aren't a fallen angel, I like you and you wouldn't hate her for being a fallen angel."

"That's true, I wouldn't hate her for that. I'd hate her for the other side."

"Yes, Azazel-sama told me that they had converted you against your will. How are they treating you?"

"Well enough, the tomato won't stop trying to seduce me. It's getting really annoying though."

"At least you are being treated well. I had heard you personally defeated Kokabiel so I wanted to come and see you in combat for a spar, would Akeno-chan be okay with me coming to the parent's day?"

I just looked at Akeno for a few seconds who continued to hold a saddened expression.

"I don't have to ask her Barakiel, i'm sorry but you can't come to parent's day. That spar though, are you gonna try and teach me your 'Holy Lightning' again?"

"Of course but fit it to your abilities. 'Lunar Lightning'."

Oooh, that actually sounds pretty cool.

"That sounds awesome but I don't have an affinity for anything other than ice. When do you wanna spar then?"

"Now, I can't have to getting some training in to be ready."

The phone then cut out before I could even reply and a magic circle formed a few paces away from me, a few seconds later and Barakiel appeared through the circle with his eyes firmly on me. He walked towards me then out of nowhere sent a fist towards me which I narrowly avoided, the bastard was quick.

After I dodged the punch I jumped away and let my ears and tail out. Once they appeared Barakiel came at me again sending his fist towards me, I blocked it by sending my own fist towards his. It didn't go well for me as my power wasn't enough and felt my body fly backwards with my left arm first. Using my tail as balance, I corrected my body and planted my feet against the ground skidding to a stop after several seconds.

When I eventually came to a stop Barakiel created a longsword out of light but didn't come towards me, he just faced me with his sword of light. Facing him directly, I summoned 'Second Star' to my left hand unsheathing it with my right and keeping a hold of the sheathe by the white ribbon. Upon unsheathing the sword my clothes were immediately changed forcing my body into 'Total Eclipse'. The silver armour and the black clothes appeared on my body radiating the 'Lunar' aura.

Once my aura started to flow Barakiel came at me again, I blocked him with 'Second Star' in my left hand but was forced to swing out with the sheathe in my right hand as he was too strong for me. Barakiel just let go off the longsword but keeping it in just his right hand, with his left he backhanded the sheathe away knocking my balance off from the force and his blade of light started to ride down my blade coming towards my shoulder.

I invoked what I knew of Genjutsuu and created a clone giving me enough time to jump back an efficient distance before the longsword pierced through my clones shoulder. I then activated my divinity causing my 'lunar' aura to shimmer as it expanded slowly around me causing frost to appear on the ground underneath me.

This time I took the initiative and charged at Barakiel and clashed my sword straight against his intentionally with all the force I could muster creating a sizeable shock-wave that rattled him ever so slightly giving me enough time to follow through with the sheathe and narrowly graze his shoulder as he just turned out of the way keeping his sword against mine.

"You've gotten used to a sword now. Did you get fed up with fencing?"

"Nope, the Kusanagi moaned at me for using him like a rapier."

"Asahi-kun's sword … Has it accepted him yet?"

I brought my sheathe back up and hit into his sword knocking it off mine allowing myself to retreat slightly.

"No, not yet. He hasn't unlocked his divinity yet, the appropriate shrine is in heaven."

'Second star, do you have any attacks that don't result in lost limbs?'

'I do, Guardian. There are two that you can use at your current skill level. A support which is doubled as an offensive attack which can progressively get better, and a passive ability which results in certain attacks you can do.'

'That's good with me, what's the support turn offensive.'

'Spinning the hilt of me will activate it turning it into a barrel which can shoot bullets at will, effectively making thrusting a good choice. Pointing the sword at allies can shoot your divinity at them, this is random due to their abilities and will buff them.'

'Thanks star.'

I then spun the hilt like it was the chamber on a revolver, it spun round completely a few times before stopping and forming twelve thin barrels that widened the hilt enlarging it and the reach of the katana by a couple of inches. Every 5 seconds for a whole minute I heard an audible click come from the sword, while the clicks passed we continued our spar.

Barakiel faced me with a cool head and wasn't expecting much neither was he expecting to lose. That was obvious, the only way I have of winning is the 'Divine Fang of the Lunar King' and lose my arms again. I don't particularly want another night of being naked with Asahi in front of the girls, and I don't wanna kill Barakiel when I actually like the guy. As with all opponents I could see multiple openings thanks to my senjutsuu and Nekoshou instincts but I wasn't strong or quick enough compared to him to make use of them, they would all result in a simple parry from him. My only bet would to use 'Feline Blitz' to temporarily mature myself.

As our swords collided once again, I started to wonder why I was actually thinking about winning. This is a spar for him to gauge my current strength and get precise feedback on my current skill and get specific training regime off of him. This means I should just go all out without thinking and strike, if I wound him so be it and if he wounds me in self defence then so be it.

Making some more space between my self and Barakiel, I strapped the sheathe to my waist by using the cloth as a belt and took 'Second Star' in my right hand and focused on the connection in my left hand. The connection was there so I was free to use it, I poured my energy there making my left hand bask in a golden light bringing the legendary black bladed katana to my hand.

'Oh Lord Tsukiyomi, you gonna use me as a sword this time?'

'If you are lucky sword.'

As I charged towards Barakiel who created a second longsword, I invoked the divinity of Kusanagi which pushed back my original divinity invoked by 'Second Star'. This caused a two-sided display where my left side held a golden-orange divinity that was rather faint compared to the silvery-blue divinity that occupied my right side. When our two swords clashed the colours mixed causing rainbow puffs of smoke to form from the collisions of our swords.

In my hands I could feel my swords revelling in combat, both of them were happy and wanting to go on but I had a small patch of envy hidden inside my body. The envy was coming from Vorpal or Lumi, to be precise. The envy was building up and quickly to the point of bursting, she wanted to join in and play. I'll bring her out in her temporary form, hopefully I can control the power well enough to take on Barakiel.

...Rias PoV...

As I watched Gin face down Barakiel, I could feel something building up within Gin. It wasn't something I felt before but it holds a definite similarity to his ice magic and the ice sword he used during the Rating game against Raiser. Even before he awakened as Tsukiyomi, his affinity for ice magic was similar to affinity with demonic magic but his control was vastly different. Despite his lack of battle experience, ice-type magic was second nature for Gin and it was something I was jealous of. Ice magic ran through his veins just like 'Destruction' magic ran through my own but his ability to manipulate it was near master's level whereas mine was basic.

His ability to stay cool in battle was something I envied about him also. It's part of what makes me like him and furious that he doesn't give me the light of day. To me he is perfect, he is everything I need and everything I want. He is strong-willed, sharp and takes no crap. It shows here is his spar with Akeno's father, I could tell from his expression after making some distance. He knows he stands no chance without killing and destroying his arms so he will go all out because it is a spar and that's where this feeling of ice comes in. His body is just starting to radiate an icy temperature while emitting an aura very similar to Akeno's.

"Vorpal Shift!"

With those two words, he hunched forwards slightly and a girl basked in a white light appeared out of his back. The girl herself was naked but covering herself with her many wings. The girl who resided in the sword, descendant of an old Maou but was a mixed blood herself. Three devil wings were hiding her left side and three dark feathered angel wings covered her right side leaving only her face visible. The girl herself was pasty but beautiful nonetheless, after emerging from Gin's back she hugged him wrapping her arms around his neck and shoulders.

Jealousy and anger was all I could feel as I watched that woman rest her head on the arms she wrapped so lovingly around Gin and looked straight at him with doughy eyes.

"What is your command?"

"We are gonna give Barakiel a run for his money and see if we can beat the top fighter in Grigori. You ready, Lumi Mammon?"

"Your wish is my command, my Lunar Prince."

I couldn't help but grit my teeth together at their show of affection. Mammon, she was the daughter of one of the original Satans and she lives inside of Gin. I would kill for even a little bit of the emotion she got from him there but she does have some nerve calling him her 'prince'.

What happened next pissed me off, she kissed him. The ethereal bitch kissed him, she kissed what was mine. The bitch has the complete audacity to be all over him, he is mine and I will make it so no matter how long it takes to do so. After kissing him, the bitch passes back into his body but left her 6 wings on Gin's back taking in his aura and thriving in it. The 6 wings stretched out happily as his icy silver divine aura coated them.

Gin then moved with grace, he didn't sprint but danced. His movements were light and quick as he dotted around in front of Barakiel while moving forward. It looked like he was a natural but looking closely I could see the base of his wings jittering about. The wings were taking care of his movements leaving him to concentrate on striking which he did. Once his first sword clashed with Barakiel's he disappeared only to shimmer back into view slashing towards Barakiel with his other sword.

His movements were beautiful, he was making the duel a show. His movements were like he was showing off, his speed wasn't too quick to be unnoticeable but it was as near as it could be and above all, he made it look simple. The strikes of his sword though seemed off, maybe empty could describe it. With his body shimmering out of view the moment the swords clash it makes it seem off but if I was to look at Barakiel I could tell they were full strikes. The whole fight since he did 'Vorpal Shift' has been like a beautiful illusion.

"Empty Fang."

Out of nowhere came Gin's voice as he reappeared moments later with both of his swords straight through the back of Barakiel's shoulder blades but there was no blood or any visible wound. I could only tell that the attack was successful from the look on Barakiel's face. His face paled as he turned his head to look at Gin's stern, emotionless expression. Looking down to the two swords in his back he showed a wry grin and forced the two light swords in his hands to disappear.

"It seems like you won Gin-kun."

He won? He beat Barakiel, a top ranked fallen angel, by not inflicting any wounds at all?

A brief flash of light revealed Gin to be standing behind Barakiel with the swords and wings gone and his hands in his pocket. As he spoke, Gin scrunched his mouth up slightly.

"Lumi beat you Barakiel, my body acted as a vessel and only that. She deserves the praise for fully utilizing my body to win with it being the first ever 'Vorpal Shift'."

"Then I will praise both of you. Your skill with a blade is improving, I could tell during the fight but you would benefit better by sticking to thrusting rather than slashing. Your strength is good and your ability to move around is impeccable. All you need to do is focus on your power, just focus on that till you gain your second tail then bother with the more advanced techniques with your Senjutsuu. When you do gain your second tail, call me up so we can gauge it."

Barakiel then nervously looked over towards us, I followed his gaze and saw it lock onto Akeno who held a look of disgust. I quickly turned back to look at him.

"Gin-kun … No. Tsukiyomi-sama, please look after my daughter and keep her safe."

With a bow of his head, Barakiel's tone turned to an extremely polite one which made Gin show a fanged smile that caused my heart to flutter.

"You have my word, Barakiel. I'll look after your prized daughter until she resents you no longer, I promise you that. It's the least I can do for you, especially when you acted like a father to me in my early days with Grigori."

A father to Gin? Gin has never been vocal on his true family, he has never even mentioned them. Why? Is it too hard for him or has he actually got past it by now? His character is too composed and he is too hostile to me for me to get a good grip.

As Barakiel disappeared through a magic circle, I could see Gin's shoulders dropped along with a sigh. His back seemed sad and above all else, far away.

"Empty fang, huh?"

I looked beside me to see Onii-sama next to me wearing a complicated expression.

"What is 'Empty Fang' Onii-sama?"

As soon as I called to him his gloominess disappeared and was replaced with a grin.

"Empty Fang, Ria-tan, was the original Mammon's famous killing technique. I had never seen it before but Gin-kun's didn't look perfected."

"Perfected?"

"Yes, with a name like 'Empty Fang' I would expect the attack or the swords at least to be invisible but they weren't. The attack looked like the swords just phased through Barakiel."

"Yup, it wasn't a perfect hit. The blades are meant to be invisible because it's a sneak attack, if I miss a killing blow then the invisibility allows my to move the sword or swords to a part of the body that would mean a killing blow. Then on command, the swords would reappear as if they were just being thrusted into the body."

I turned round to see Gin willingly talking to us, joining in on our conversation surprised me.

"What did Barakiel mean about you marrying Akeno-chan, Gin-kun?"

Onii-sama, thank you. I couldn't of asked that question myself but I really wanted to know the answer. When I looked to Gin, he sighed while closing his eyes. When he opened them again he spoke with a bored tone.

"He wanted me to marry her not of out acknowledgement but because he truly likes me as a person. Despite being in the Hyoudou household at the time, during my first year at Grigori I spent most of my free time with Barakiel and quite frankly he spoiled me. At first I was a substitute for Akeno, that was easy to tell. He was a complete wreck when I wasn't around but quickly he started to see me as me rather than just a substitute. We went out and did things like father and son, he even took me shopping sometimes and we'd look through sport stores. At one point he was going to adopt me but something held me back from agreeing and stayed with Issei, maybe it was the mother figure that I yearned for. I don't know. Despite everything with how kind he was to me, I can't help but think that he wanted to marry me to Akeno was so she was protected at all times. He wanted someone he could trust and confide in to look after her, keep her well and blow away all her worries, possibly even bring them back together."

The smile Gin wore throughout the explanation was troubling to me, I was happy that he felt like he had gained something that he had previously lost but there was something amiss in his smile. Something that picked at my heart, something that made me feel like he was hurting despite the happiness. Despite wanting to do something, I just listened as he continued.

"He was my fencing instructor, he taught me to use my ice magic defensively and offensively. He was the one who became my father figure and also tried his best to be a motherly one too. He taught me to be domesticated and violent but not without reason. He taught me the reason to fight and why I must, to protect what's been lost from escalating.

We have both lost loved ones, people we loved with all our hearts but couldn't do anything."

The trouble started to show on Gin's face as a tear formed in the corner of his left eye. That lone tear wretched at my heart, even though he was only on the verge it tore through me. I wanted to hug him and console him but I didn't want to anger him at this moment in time.

"I feel that out of the two of us, I was the luckier one. Compared to him, I am young and can have another family easily but the loss of my parents is still there except it's limited. Barakiel on the other hand, was not so lucky. He lost his wife, the woman he loved with all of his heart and his daughter, the girl he adored with all his heart. He went through the agony of seeing his dead spouse and then it was worsened when his only fragment of happiness left looked at him in disgust and shouted at him. His own daughter left him when his heart was broken. He wasn't able to save his wife, the women he was devoted to but he was able to save his daughter, a girl who has is almost a replica of her mother only to be hated by her."

The tear came down the moment he started and the rest came down as he continued. It seemed like he was repeating himself but each word deepened the feelings he was showing us. Pure feelings.

"Hated by what he had left. You aren't meant to kick a dog when it's down, it's horrible. He has lived with the guilt for years but continued to look after her from the shadows. He doesn't deserve this any more."

I had had enough. I ran straight to him and wrapped my arms around him, he was too vulnerable to even fight back. He even placed his arms around me and gripped onto the back of my top as his streaming tears turned to a waterfall and started to cascade down. In mere seconds I could feel the front of my t-shirt drenched and sticking to my skin.

He was crying out of pure love and anger. He loved Barakiel, that was obvious. You could tell from the emphasis of his words but his anger was stronger than his love. He was angry at Akeno, he probably couldn't take how she shunned him. His experiences with Barakiel will make it seem terrible. Additionally, she still has her father where Gin doesn't. The circumstances for the deaths were different but the end result was the same, death. It doesn't matter when it comes to death, it's forever.

Everyone's gaze turned to Akeno. We all wondered whether she would give Barakiel a chance, even if it was just for Gin's sake but she couldn't. She turned her head away to try and escape our gazes. She was troubled herself, what Gin said would annoy her as well.

All I can do is hope, hope that Akeno gives Barakiel a chance and be completely happy.

Phew ... writing as Rias was weird for me but was fun.
I got to bring across some pretty important story details here. Barakiel is the top fighter in Grigori as mentioned in the canon.
As top fighter he gives the new recruits basic training and takes the top student in for extra training but in this batch, it was Gin through special circumstances.
Somewhere along the line he started to treat Gin better and it spiked going elsewhere.

Well, that was the start to the new arc. Some new info and a fight which ended in an outsiders win, couldn't be better. I'll see you next time, Ciao-nya.
