So, from what I've gathered, it's implied that Rias and Vali actually have their family signature powers all this time and I was like… "WTF!" Are you saying that Rias and Vali always have Gremory and Lucifer's power but they never use it?

What? I always thought Rias only inherited the Bael power. And I thought Vali didn't inherit anything from his devil bloodline because he was half-human.n"They probably don't even know about it?" That doesn't even make sense, how could Azazel or Rias' father never mention it to them?

Well, enough with the rant… now, to the story that I don't own anything other than my oc and ideas.

Chapter 04: Big sister awakening, part 1.

Unsurprisingly, my debut in the Devil Society was rather anticlimactic, far from my expectation when I was a child… even though I'm still a child now.

However, I suppose I can't complain about it because not everyone needs to be as theatrical as the main character and his gang. I couldn't have asked for more as a supporting character; this satisfied me completely.

I know I stated it was anticlimactic, but it wasn't as easy as I had expected either.

Sincerity be damned, I still don't understand what's their problem with me. Generally speaking, I can see why they did that; in the end, their enormous ego was the primary issue. Although I do understand, this does not mean that I should accept it.

The bitterness and jealousy they harbored toward my big sister and her gangs.

When we entered society at age 12 and began to establish our reputations in the Underworld by taking part in social events and as we grow; rating games or any other big event.

The noble devil was regarded as a member of society.

I'm already 17, yet the number of times I fought in rating games was zero, for some reason, I just can't get any chance to participate... Politics is such a pain in the arse.

They were anxious about keeping me at bay, kept the spotlight away from me, for one reason: as Leviathan's younger sister and a rising star in the underworld, they don't want the world to know there will be another big shot in the Four Satan faction. Where they have none in their group, I mean other than the Original Bael none of them are much of a threat in any way.

The elderly in the... What was the name of their faction again? I had forgotten… I forgor… lol.

What matters is that the oldies outside my family and our allies feel intimidated by my progress; some youngster who isn't even a tenth their age is already stronger than them; it must be humiliating to them... Aren't they in the same gang as the guy who expelled Sair-something fellow a few years ago simply because he didn't inherit the Bael's power? Acting highly and mighty, tch.

Boomers, with their flawless intelligence, think they are always right on everything... Thank you for sharing your infinite wisdom with me.

An explosion was heard in the distance, far behind me, as if on cue... That's where Merlin is; I'm confident and believe in her abilities, but given the number of opponents, even someone of her caliber could get into problems if she isn't careful.

I deflected the impending strike on my left without even looking.

"Are you certain you have time to spare for your girls? It's not too late, why don't you give up?" What a repulsive expression.

Wah, creep, please don't mention my girls with that expression. I can read your intentions like a book, man.

Rats, why does my debut opponent have to be someone as disgusting as him? As expected from the third-tier character, his character sure is lame as hell.

"Well, don't give me time to be distracted in the first place, old man…" you can see his eyebrow twitch at my provocation.

What I'm doing right now is just a classic battle between two forces: defeat all your opponents or take out the leader first to win, that is. No special rule whatsoever. Simplest and most sacred way to prove your supremacy.

"Honestly, kids these days don't know how to talk to their senior…"

Talk about being a fucking boomer.

I knocked his sword away from me with little effort and the next move I aimed my spear at his legs, but it sliced nothing but a void. He jumped, creating a large space between himself and me.

Stay still fast bastard, so I can rip you to shreds. I lay my spear on my shoulder because there's no hint he'll launch his next attack immediately... taking your sweet time, aren't you? Well, that works in my favor as well.

"Well, as a senior citizen, may I ask you a question?"

"Hmm?"

"Why do old people always want to discuss their theories? Consider how we feel as teenagers having to politely listen to your babble. I don't want a crease on my lips from all of this hypocritical smiling."

Even at this distance, I can clearly hear his veins popping.

"You filthy brat! I'll make those words stick with you!"

"I'm sorry, but the only advice I'll listen to is the ones from my mother."

From my peripheral view, I noticed someone crouching behind the building's ruins, and in an instant, it was shattered by a swarm of throwing knives that slashed the air at breakneck speed. I stop the strike by calling a pillar of water from the ground without moving an inch of my body.

"See? Because you talk too much, your little friend got too relentless…"

His knight, huh? Better take him out first, it would be annoying to fight them at the same ti- Ping-

Hmm? The sound of an alarm emanating from the blades drew my full attention to the source. Before I could process what was going on, the blades began to shine, and soon a sequence of explosions followed.

Leaving me intact because my water barrier is activated instantly by instinct, but wait a minute, it's a cool technique, so by anime logic, I have to name it, huh?

"Aqua Sphere..." sounds like a decent name.

Still, he enchanted some explosion spell into his weapon, wasn't he? Maybe I should try something similar with my water globes. My time for fantasizing has been cut short as I sense another presence hovering above me.

He hammered me with a giant boulder using all his strength, strong enough to demolish my water barrier, and his strike caused a little earthquake.

Why are there so many of them, you ask?

We were badly handicapped in terms of numbers; it was 13 vs 3, and looking at the numbers alone, you'd believe it's not even a contest, which is presumably what the boomer thought when they planned this match.

Knowing my chance of winning was like a snowball in hell. They're probably already planning a party to express how upset the citizens will be with my performance.

Sera-nee even offered her peerage members and herself to be temporary members of my peerage. They have the arrogance to make her worry after everything she has done for me. I could calm her down by informing her that I was certain of my victory and that I had a hidden trump card, but it would ruin the surprise factor.

Before they have the chance to celebrate or keep up the combo, I destroy the boulder, appear with a minor injury before them… I suppose this concludes the game. Still, it came as quite a surprise to think that someone other than the King and Queen might be able to breach my defenses in his group, that was outside my calculation… and great, his other peerage is here as well, man… how annoying.

They had underestimated me by only sending 1/3 of their member, but after so long and the battle hasn't ended yet, I guess they became a little restless or just bored waiting.

5 vs 1, huh… good, it's the right time for the demonstration. Well, from the start I'm planning to take his whole group alone.

If possible, I want to take more damage, but I don't know what Sera-nee will do if I look worse than I already am.

Looking to the other side of the arena, the explosion is still going on with no sign of stopping, Merlin's battle is still going on, huh? And I'm sure the rest of his group has been sent as extra support.

I know it must be hard, but keep them in your position.

In relation to that... Kuroka, you could have done more before you kicked the bucket, you know. Is this how you repay me? After all the trouble I took to rescue you from the Naberius clan.

("I tried my hardest, nya!" In the infirmary, a black-haired Nekoshu yelled to the medics tending to her injured body, "Man, what a bastard!")

"It's 5 vs 1, there's no chance for you now more, why don't you just give up already?" The new dude, his pawn, said with a jovial tone, clearly looking down on me… what an ugly mug.

"Don't lower your guard, this kid withstood my strongest attack with little damage much to my surprise…" Man, this place is not for an old dude like you, you should stay at home and spoil your grandchildren, pops… how old are you anyway?

The others contributed their cringe dialogues as well, but I chose to disregard them because it wasn't essential anyway. Who gave them the right to speak like that in the first place? What do they think this is? A final fight in which the fate of the world is at stake? Guys, it's only a game! Calm down, man.

My already exhausted body became even heavier as they prepared for the coup de grace. As though waiting for his turn, my opponent's king patiently stands still with a smug expression; I'm sure he believes he has already won this match.

Sigh, fuck this, before he could say anything, "[Eternal Youth]" Streams of water formed from beneath us at my command, tossing them to the sky and forcing them to summon their wings to balance their bodies.

Shocked, because not only is the ground around us creaking from the water jet streams, but every spot and corner of this arena has been demolished by my water pillars. After the streams subsided, the once-forest-like stadium resembled an area that had recently been wrecked by a massive flood.

They looked at me standing on the lake with wide eyes. The fact that the seas were red didn't help their shock either.

Even though I try not to, I can't help but feel a tinge of excitement in my heart. "Now, It's showtime."

"It's about time, young master..." Looking behind me, I notice a white-haired woman with pink gems in her eyes, her body and clothes heavily damaged. Her lovely beauty was complemented by cute pouting.

Sometimes I wonder how she is even here. I'm not the biggest fan of DxD, and I can't claim I recall every character in this series, but I'm sure I've never seen a female like her in the anime, fan art, memes, or anime forum. Not to mention that the only white-haired girls I recall from the show were the Valkyrie and the maid.

A gorgeous girl with the characteristics of Akeno and Serafall like her would win the viewers' hearts, but Merlin was scarcely mentioned in the series or forums as far as I recall. She, too, was not a reincarnated being like me.

So, I've determined that she was an extra in this world, or that this was an entirely different version of DxD for me... some kind of compensation for sending me here, or something along those lines.

There was another reason I was certain she didn't belong in this world... Merlin's breasts are of ordinary size. It's not bad, really; I love her adorable size, but if you're an adult lady DxD character, you have to have two melons hanging down on your chest.

"Sorry about that, Mer."

With a cheeky "Hmph!" she throws her face. "Sorry did not cut it! Holding back my power so I don't accidentally kill them was harder than I thought… look at this!" she says, pointing to the light bruises all over her body. "This! And this! I'm filthy!" Yes, you are... Also, watch what you say, lady.

Well, she's not going to back down anyway, "After this, I will do my best to make it up to you…" Let's just give her what she wants.

Hearing the defeat in my tone, her pink lips formed a bright and mischievous smile with a hint of hunger. The next thing I knew, my arm was locked between her breasts, and she was tip-toeing her mouth to my ear.

Oh, did I mention her breasts aren't the only thing about her that is lovely in size? She also has a cute height.

"That's what I'm looking for, and don't forget to call me Onee-chan, okay?" Her warm breath tickles my hormones, so I push her head away before I lose control and "attack" her.

"Can you please stop provoking Sera-nee?"

Before she can retort about who "Sera-nee" is, a massive fireball is only a meter away from reaching us, and a thunderous explosion shakes the entire region.

"You took me by surprise... But don't believe you've already won the war!" He raised his hand, and a massive fireball erupted from his palm. It was so bright that I could feel my eyes drying up. "I'll blow you away, along with this damn water you're so proud of!"

Oh, someone is upset because of our flirting. -That fireball had more strength than any of his previous attacks- and when we emerged from the steams, his shock was obvious due to how severe my condition was from his assault; perhaps he expected me to block his attack? My charred arm went against his expectations. But my confident grin remained, while Merlin stood calmly behind me, giving him an uneasy feeling.

"That's where you're mistaken... You've already lost when I'm your opponent..." The water underneath them begins to rush toward them with the flick of a finger, faster than they can react.

"It's just water!" Don't undervalue me!" He probably expected my water to evaporate the instant it got close to him, but his arrogance was short-lived; my water effortlessly enveloped him, and his flame, extinguished it without a problem.

After my attack passed through them, the next thing we heard was his group's agonizing cry, which was so awful that it was pleasant to hear. I control the water to me after what stolen is sufficient; the minute the water surrounds me, the wounds in my and Merlin's bodies vanish without a trace… on my sign, Merlin begins doing on her part.

"Wow, my body feels so light, behold this therapy power!"

She summoned an illusion of herself.

"Wow, amazing!"

Why is she talking with herself? Man, I leave her alone on this because she asked me to, but now I'm starting to get worried.

With -WOW- and -WAH in the background, where did that sound even come from? She continues her demonstration with an extravagant tone and moves.

"This treatment will cure dry skin, wrinkles, stiffness body, internal/external injury, and many other issues! You may wonder where you may find this. Don't worry, this will be available in every Sitri hospital and clinic. You will receive a 30% discount if you are one of the first hundred buyers! Now dial our number and fill out the limited appointment form! Also, what you see now is the fighting version; the gentler and softer version for therapy can be found on the sites I previously mentioned! If you happen not satisfied with our service, you will get a 100% refund!"

"You must try! If you still worry about the safety, don't worry you can try the free sample!"

"Our products are cheaper than the P****x T***s!"

The two Merlin closed the funny segment with a -Banzai- gesture. They glanced at me after she concluded her -This is 100% not a scam- speech and said, "What do you think of my great advertainment skill? You can begin by sincerely praising me, you know," not to mention her starry eyes and a smug smile.

"…" My deadpan stares were what greet her.

Wtf, Merlin, this felt like a scam product now, and why are you even picking a fight with the fire chicken… well, no matter.

My final goal for this battle is to advertise my newest investment. To be honest, I don't care about the outcome, but if I can win it and make my family proud? Why not.

I can steal my opponent's life force, nutrition, and magic with the [Eternal Youth] red water... Not to mention that I can manage the temperature of my water above boiling point without getting steamed out, making this water my Trump card.

At first, I wanted to use ice manipulation like my sister, but I'd realized she was an anomaly among the Sitri, a superior being born from evolution; not everyone in our family could use ice like her, and I was one of them.

"It's boiling... This blasted thing is burning my skin... fucking brat!" He paused before giving me another scowl. "You! How dare you mock us!" The king was the only one who could still fight, while the rest were ready to get out of this mess. Sorry, but you are not allowed yet out of action; I only took a little out of your life force and focused more on external damage precisely because I still need you to stand in this battle.

"Oh, please stop talking..." I directed my spear upward, and this time a much larger wave assaulted them; in the previous attack, they were still able to hold their balance despite the torrent, but this time they can't do anything but be overwhelmed by the tsunami attack and fall into the little sea I created.

"I've already accomplished my goal, so I'm done holding back..." I formed a massive whirlpool with another swing of my weapon, trapping them and tearing them apart.

Of course, knowing the gravity of the situation, they will not sit idle and do nothing, but every time they try to free themselves from the whirlpool, another wave would hit and pull them back into the depths, and the king will realize how much I held back from the moment I clashed with him at that moment.

Since the beginning, I've always fought him at his level, but today he can't even raise a finger in front of my full strength.

I increased the severity of my attack with another swing and drew them towards the center of the vortex, allowing me to concentrate all of my strength in one spot at the same time, ready to be released... and with a snap.

"Boom."

A pillar of water blasted to the sky and left a crack in the ceiling of this man-made place, this scene reminded me of the movie Knock Up Streams in One Piece... To my credit, I was able to leave a gap in the dimension wall that Beelzebub himself constructed, thus this unexpected result was a wonderful surprise.

My victory was sealed when the announcer announced my opponents' conditions.

Even though I knew I'd win from the start, hearing "Yay!" still makes me elated.

.

.

And now, after a brief pause, I'm sorry but I'm not interested in detailing the mini-congratulation celebration that my family organized for me. I appreciate the sentiment, but when you already know you're going to win, it just doesn't sit right... that's not to say I'm not having fun, though.

You can't just refuse your family, no matter how trite and predictable it is.

Besides, watching my parents' proud expressions, the real eyes they wore from the moment the match ended until we returned home... it's just damn... I can't put it into words; it literally gave me butterflies in my tummy, you know.

After ensuring that Kuroka and Shirone are well-rested in their rooms, I retire to my room. With a glass of cold mead, simply relaxing my body, allowing the night sky to shine through the open windows... Merlin was hot on my tail. What is her purpose in being here? Well, what do you think happens when a teenage boy and a young girl are locked in a room together?

"Ahhh~~~ that was a good party~~~ a well-earned indulgence was always better than a simple pleasure~~~ your mother always knows her stuff~~~" She writhed in my bed as if she owned the room, which she may have, a moan interrupted each of her words. She was no longer wearing a layered dress, but instead a see-through nightgown, ruining her once balanced cute and seductive allure; now the sensuality had overwhelmed her entire charm.

I swear, this girl is a walking sexual desire. You know, you can say that without moaning and being erotic?

"So? What are you looking forward to, young master?" rising, her half lid eyes locked into mine, "Come here, it's time for your true reward," she added, patting the space next to her.

Who can say no to that? Just so you know, there was a lot of buzz, especially from the Boomers gang, about how I managed to bring one of the most famous wizards in human history into my peerage. As for my family, they were overjoyed that I could bring in such a prominent figure as her,… excluding Sera-nee, though for some reason… well, she was always moody.

When we were just getting into the good part, I mean my tongue in her mouth and her tongue in mine, with our saliva trailing in our chins and my hand caressing her breast while the other explored her hair and deepened our making out, someone opened, no, she threw my door open without permission, but the moment she realized what we were up to, her beaming smile turned into a completely shocked face.

Maybe if I focused more on her, I'd watch her surprised expression transform into a vengeful gaze directed toward my Queen.

"Sera-nee, would it kill you if you knoc-" Whatever I was about to say was stuck in my throat as every being in me, every survival instinct screamed at me, and for obvious reasons, I was late a moment to defend myself. What happened next was that I found myself flying, no, I was sent flying, in the sky outside the mansion with Merlin taking me in her arm.

Her passionate and fun look had vanished, replaced with a solemn one, but what drew my attention was the horrid damage to her body. "Gee... that was scary..." she whispered, her right arm and part of her face completely immobilized by the ice. Even though she was smiling, it was clear that she was suffering from a terrible ice burn... I'm not even sure whether she can feel her arm in that condition.

When I looked down at the mansion below, it didn't take long for me to realize why I was here in the skies instead of in bed. I noticed that half of Sitri's mansion had been wrecked by massive icebergs, which were pointing to the sky like gigantic spears.

What the hell is going on? Did my sister just try to kill me?

-TBC-

Sena's power is inspired by Kinjiro (Bleach.) I can't believe I wasted 3k words for the first part of this chapter. Let's just pretend Sena's opponent was a random prominent member of the Great King faction, I don't know who are the members though… they are irrelevant.

Whoever left the last review on this fanfic, man, you should write your fanfic. I was almost giving up on Kuroka's mother being the peerage member because that would just be too hard to write, she was blindly in love with someone after all, but you just came and gave a lot of reasons about how she would be there without being awkward… which also gave another idea for Sena's peerage member.

King: Sena Sitri (17)

Queen: Merlin (23)

Bishop: Kuroka (14)

Bishop: Mobius (25, Honkai Impact 3, a researcher he got from the Naberius' facility. Prefer to stay at home, a non-fighter)

Rook: Fujimai (38, Kuroka, and Shirone's mother, currently being held in the Sena's private "clinic")

Rook: -

Knight: (Probably Xenovia)

Knight: Sara? (A Tengu, Genshin Impact)

Pawn 2x: Shirone (8)

Pawn 1x: Lilitifa Vepar (joined to get his protection, also a non-fighter)

Pawn 5x: -

Merlin, Kuroka, Mobius, Shirone, Lilitifa, and Fujimai (just imagine Kal'tsit with purple and white hair instead of lime green, because Fuji means purple in Japanese lmao) are confirmed… well, that just leaves two knights, a rook, and multiple pawns… probably I will add one more named character into the group and fill the rest with some random NPC.

I love how messy his peerage is, lol.
