Highschool DxD: Dragon's Ascent

"Rise and shine Mr. Fre- ahem. Rise and shine sleepyhead." I gently woke up Akeno who was still lying in my bed, she was completely knocked out like a log after I had fucked her into unconsciousness. A few beats passed and Akeno opened her eyes slowly before they snapped wide open.

"That wasn't... a dream? Good morning to you too Takumi-kun~" Akeno said with a sexy sleepy voice full of adoration as I smiled at her too, she looked adorable having just woken up like this.

"Good morning to you too Akeno, did you sleep well?" She stretched, forcing me to avert my mind to not get bricked up so early in the morning again, as Akeno got off the bed but when she tried to put weight into her legs she struggled to stay upright like a newborn fawn.

"E-eh? Thank you, Takumi-kun. It seems like we may have gone a little... over... board... last night..." Akeno said as I helped her up before her sleepy mind seemed to recall what happened and all of the rather passionate things she had said during our tryst.

Red crept up her face as she averted her eyes from me. Adorable.

"E-erm. T-Takumi-kun? I didn't embarrass myself too much last night... right? I may have gotten a bit too into it last night." Akeno looked like she wanted to crawl into the floor.

I can't resist.

I put on a surprised expression as I faced her as if in disbelief.

"Wait. So you aren't a masochistic slut who wants me to you into my personal breeding cumdump?" Akeno looked just about ready to die from embarrassment.

Akeno leaned into my chest with smoke coming out of her head as her fist weakly pounded on my chest in indignation. Akeno muttered, her words muffled by the bountiful pecs she was buried in.

"You are too cruel Takumi-kun, you shouldn't tease a lady so much when she is so embarrassed. Besides..." She raised her head up, still blushing a burning red but this time with heat in her eyes.

"I never said I wasn't~" This woman was going to kill my heart.

After having breakfast with Akeno I walked her to school much to her happiness. I had a reason for this other than making my new girlfriend happy of course.

I was heading down to the underworld tonight to start my operations there and I wanted to ask Rias if she wanted to come with along with her peerage. But contrary to my expectations...

"Unfortunately, I don't think I can come with you Takumi-kun. No, more like I dont think I will." Rias said with a resolute expression leaving me slightly dumbfounded.

Eh?

"Why? It isn't like I am offended but I thought you would have preferred to come with me. Is there something important you have to do or something?" Rias nodded with a serious expression.

"More or less, I have realized that recently that without you being there to help us we would not have even come close to winning, I am even falling behind Sona. And I dont want to have to be dependent on you for everything, even though I will of course be counting on your help but..."

"I dont want to be a burden to you Takumi, I dont just want to remain behind while keep getting stronger and more important by the day. I am Rias Gremory after all. I am thinking of expanding my peerage and training more consistently." Rias said with a proud expression as I was internally surprised.

I... did not think Rias would actually take it to heart that much. Yeah, I let them get beaten by the Riser peerage for precisely this reason but from the look in her eyes, I could tell that she was completely serious. She didn't just want to remain in the background while I soared, as expected from the pride of a devil princess.

Honestly? I was very proud of her.

"I'm proud of you Rias, or I guess I should say as expected of my wonderful girlfriend." Rias puffed her chest up in pride. "Then I won't stop you in the least. If you want you are always welcome in my house, if you need something have a maid take you down to the basement and ask Arc for anything, he has access to all of my potions, weapons and in between." Rias beamed at me and got up before hugging me.

"Thank you Takumi, we will be relying on you. Don't worry, trust me, we will surprise you by the time you are back. So look forward to it." I did.

✧—•✦•—✧—•✦•—✧—•✦•—✧

"Are you ready Taku-tan~? There are a lot of people just itching to meet you you know? Just like piranhas but worry not with you big sis here they can't do anything to you~!" Sera doted on me wearing her formal outfit while I wore my new outfit.

I decided to dress fully for my debut into the underworld, wearing a classical suit and tie with a large coat over it, of course, they were enchanted with self-repair, reinforcement and Boost(10% stat increase). Even tank rounds wouldn't pierce it, it would at most scuff the outer layer.

Overall, I looked like a badass mob boss which was the vibe I was going for, once I was in the underworld I would be meeting a lot of big shots for me to scam as hard as I possibly could.

If they were the piranhas I was the shark.

"I'm pretty much ready. But do we really have to go by the train? Wouldn't it be faster to just teleport?" Going by train to another world, while sounding like an amazing experience sounded pretty damn inconvenient compared to teleport and I hated wasting time.

"Yup! It's tradition to first go to the underworld by train for new devils, dont worry the sight is to die for!" Then her face gained a sadistic hint for some reason "Also, on the train, you can take the time to read the documents I have prepared for you. Welcome to the hellish world of infinite endless bureaucracy Taku-tan!" She said with sadistic glee, pulling out a large stack of papers from god knows where.

Well, unlike how she made it sound, I did not mind it all that much. I had thought acceleration and mind partitioning to deal with all of that.

"That's... a lot of papers." Serafall smiled smugly.

"Yes! I spent some time compiling the important things you have to know and the people who would want to meet you, as you asked me to I put some elbow grease into advertising your new shop and auction as well as "letting it slip" that you were thinking of selling some important stuff. So make sure to read it carefully alright? Or else you'll break your sis' poor heart."

Even without her emotional blackmail I still would have memorized them and processed them but damn would managing those would get boring as hell eventually, I don't want to sit down and just read documents for 50 hours straight.

Hah, I'm kidding of course, this is why I have maids, plus I have Grayfia, the queen of a satan who should already be used to managing this stuff.

Speaking of Grayfia, she has been very busy these last few days to come to my mansion. No doubt due to still dealing with the very angry and disgruntled Phenex family squawking in Sirzech's ear about fixing Riser's situation and his father who would be very angry about losing relationship points with the Phenex.

Good, I liked none of them anyway.

"I'll make sure to look over them thank you... Sera-nee." Hearing my words Serafall blushed and clenched her fist, looking very accomplished with herself, I hesitated to call her that, honestly she felt like something was very much deviant with her and I was slightly apprehensive of her.

"You are welcome, my cute little brother! Since you are ready let's depart!" Well, at least I appreciated having Serafall next to me than not, it's better to suffer bureaucracy with others than alone after alone.

✧—•✦•—✧—•✦•—✧—•✦•—✧

This is a pretty damn snazzy train.

And this is both existentially terrifying and beautiful. That was all I could think to say as I looked on at the endless Dimensional Gap, I had been there. Did that mean there was a chance that my original world still existed somewhere beyond that endless, infinite veil of chaotic mana and nonexistent space?

Whelp, that thought is going directly into the existential dread folder in my mind.

Tearing my eyes from the gap between worlds inhabited by the god dragon preventing outer gods from invading our world I read the paper Sera had given again.

Basically, a decent bit of Devil families wanted to meet me but I planned on responding to them only by proxy as I had no intention of meeting them until I fully flexed my alchemy muscles and showed them that I was Ajuka 2.0 and just straight-up Yahweh 2.0. If I met them before that they would think they were hot shit compared to me.

They weren't.

Though I did chuckle a little when I saw a note attached to the page about the Phenex Family.

'Please fix this already ㅠ︿ㅠ'

Honestly, all the Phenex family had to was to earnestly apologize and maybe let me harvest some materials and give me a batch of Phoenix Tears and I would let their son out of the forever box. It wasn't that difficult.

After reading the paper over a few times and committing all details to my memory I put it in my inventory and resumed watching the scenery at some point it had changed from the dimensional gap to a new sight, we had finally arrived at the underworld.

And wow, it was actually a very captivating sight, the teal sky and the vaguely German architecture of the territory we were passing by. Seeing my expression Sera sat next to me smugly with a proud expression.

"Behold! The Underworld and technically your new home too, isn't it great? Sometimes when I get sick and tired of my work I just like to take a trip through the skies and watch the underworld and feel motivated again." Hearing Serafall speak so honestly made me surprised, her expression looked very pretty like that.

"Indeed, it really looks pretty from here." I had to admit as Sera wiped her nose smugly "I know right?" As we both settled in a comfortable silence and watched the underworld we had finally arrived near Lilith as the conductor's voice rang out from the speakers inside the cabin.

"{We have reached our destination.}"

After the admittedly shorter than I had anticipated train ride, we left the train and flew to my mansion with our wings, as we soared close to the ground I heard gasps of awe and admiration from the common Devil populace as they saw Sera and pointed out to her. I had almost forgotten she was one of the 4 leaders of an entire race almost as large as the human race.

Seeing her in person would be like seeing the president of America who holds enough power to evaporate the quarter of the planet.

Shortly after we both landed in front of a mansion I recognized from my own designs, my mansion was on a mountain on the border of Lilith with a perfect view of the gorgeous piece of devil architecture. I hadn't expected such a fine piece of land when I allowed Serafall to pick how she did this. I just sent her the design and told her to pick any location.

She opened her arms wide and presented me with the mansion with a proud look.

"Well? How do you like it? Normally even the higher-ranked devil nobles cannot get mansions in such spots around Lilith but Ajuka made an exception for you after some coercion from me. I even commissioned the mountain. Isn't it great?" Serafall nodded to herself clearly demanding my praise, she really liked doting on me, didn't she? Well, I wasn't going to deny any help I could get.

...Wait.

Did this make Serafall my sugar mommy? Sugar nee-san!?

...Damn, that just may be the case.

"I love it Sera-nee, it's even better than I imagined," I said with a broad smile as Sera looked like she was electrocuted for a moment before lunging at me and pulling me into a bone-crushing hug.

"Mou~~~! You are just too adorable Taku-tan! I just want to shrink you down and keep you in my pockets to myself forever!" I paled.

Please don't.

A/N: Rias finally locks in unlike her cannon self after seeing how far Takumi is going and how helpless she was against Riser, she is going to take her peerage building more seriously and may even pick up a few characters who haven't gotten any screentime yet into her peerage who knows(I am not implying its Issei)

Also, just like Todo from Jjk Serafall has internalized the fact that Takumi is her little brother and she isn't interested in hearing objections to the fact. She may have a few screws loose but almost all stronger people do.

It's finally time to enter the Underworld Arc.
