So before we start anything, I'd like to say something regarding romance and Issei.
Issei will not have his huge harem here, sure a few canon members will be a part of it, but it's going to be SO much smaller then canon. People won't randomly fall for another character ether, unless there's a very good reason.
There is absolutely less than 0% chance of Tachie EVER dating or even having any romantic interests in Issei.
I will have new ships, and characters won't just become useless because Issei is taking care of everything.
Will Tachie have a harem? I have no idea truthfully, I haven't even decided what gender she's attracted to! Romance will come eventually, but it's not going to be the rushed garbage from canon.
Truthfully I haven't planned every romance, but I do know I want romances that actually make sense and not just "HAREM!".
COMMENTS!
Narriz: I haven't decided regarding Tachie's armour, she already has her Demi-Servant armour, which you can see on the Wiki page. However she may eventually get Galahad's actual armour as it'd defiantly have some kind of magical property.
Bear Lord: Ah sorry, my writing isn't the best, I'm trying to improve but it's slow. And I didn't know that about fires, thank you for the information.
Kolt999: It's something I've found I'm good at without even trying.
hmataco: I'm probably going to time skip large portions of the training, but do some of the important bits like learning how to wield a sword, magic, and all that stuff.
Nastadoa: That's a good idea, thanks.
Guest: I suppose that is possib- (The Entity: I'm afraid that won't be an option). But it's funnier this way.
Ol' QWERTY Rando: Huh, seems a few people are very interested in Tachie's relationship with Olivier over the training, I'll have to grant that wish.
I'm currently planning to do short scenes for Tachie's training, like learning magic or how to use a sword. Tachie is never going to be unrealistic, her skills will be gained realistically, and that's why she's having a few years to train before starting the canon events. Her strongest advantage is her Demi-Servant form, which will give her insane durability. Even when she gains more abilities from The Entity, she's not going to start spamming EA or Excalibur's.
RhoMarck: Thank you.
Guest 2: Honestly I have no idea, but if need be we can just say had had kids after getting the Holy Grail. DxD does mess with actual myths quite a bit *stares at all the things that were turned into dragons*.
myfunvideos: I've decided only to do some scenes for the really important training bits like learning how to first use magic.
Souna Lucifer: Thanks, it actually does really help.
Alnistiona: My current plans for Kuoh are just visiting for the Excalibur Arc, this story is Tachie's adventure, sure she'll join adventures with Issei a few times, but this is HER story.
Dear God I hate how many fics have someone be turned into a devil, there are other things out there you know! It's always played as "Oh the church is filled with corruption, but the fallen and devils are okay", no just no! They all equally have corruption and good sides. Main reason the Church is being shown as "evil and untrustworthy" right now, is because Olivier has a bad relationship with them, Tachie will meet good people from the Church, Devils, Fallen and other factions, but she'll also meet bad people.
Olivier and I had been travelling for a few weeks now, my training hadn't been anything interesting yet, mainly focusing on improving my body through exercise and teaching me about the supernatural world. I had learned quite a few interesting things, and was extremely thankful even with his own distaste towards the Church, Olivier would tell me non biased information.
I had learned where the different territory of different factions were, how to interact with them, and how to tell them apart from normal people. Apparently one of the best methods to spot a supernatural, is how attractive they are… I feel disappointed in this.
Anyway back to my training, I quickly found my body was already pretty strong, Olivier was incredibly confused by my body which was far stronger than a normal human. I suspect this was my Demi-Servant status, my body was already stronger than an average human, and I can't wait to see how strong my Servant form was!
However, Olivier quickly beat sense back into me, my body may be tougher then a normal human, but it was no match for a trained fighter, and defiantly not a match for a supernatural. But finally, I had 'passed' the basics, and Olivier would start teaching me how to actually fight.
"Okay kid, we've finally got you past 'newbie' into 'in-training'. You'd still be wrecked by anyone with actual training, don't get cocky because you're stronger than the average human. We're going to head to Foyki now, whatever you do, don't mess about with the devils there, while there are some good ones, I don't want to risk you running into a bad one". Olivier explained, his care for me was… really nice. My original life parents had raised me, but they hadn't given me much affection, Olivier's care for me was, just really great.
We drove the RV to Foyki, it was a beautiful sea side town, tons of supernatural's just walking about, and their unnatural features fully on display. There was stalls and shops filled with magical items and enchanted weapons, Olivier had to actually drag me away from a paper dragon that was flying about.
"The main thing you need to worry about here, are the few gods that show up". Olivier stated, and this caused a bit of worry.
"Gods? I didn't think any gods would be interested in such a small town, even if it's this beautiful". I asked, confused why gods would be interested in this place.
"Not the big tier, lower divine spirits, strong and divine yes, but you won't see them throwing around city destroying power. But gods of any tier are tricky, they have powers over nature and the world itself, but they make good allies if you can get them fond of you. But not too fond, you don't want them lusting after you". He explained, ah I get it now. So it was low tier gods, but they still had divinity classifying them as gods. And of course, some of them are obsessed with people, because why not.
We travelled around the town, stopping at a few shops to buy things, however one item made me freeze. It was a beautiful sculpted vase, but the image on it was anything but kind, a woman with a body that was absolutely stunning in every way, inhumanly beautiful. In her hands was a golden cup, leaking a black liquid. I'm not sure why, but this image but attracted me to it and repulsed me.
"Oh? Interested in that old thing are you lassie?". The store owner asked. "Apparently it's an image of the 'Woman of the End', an enemy of the God of the Bible, who tried to drown the world in sin. Nobody's quiet sure if she actually existed or not, but it's a creepy thing isn't it?". Woman of the End? I've never heard of her but, the image is so familiar.
"Hey kid we're, done here. Stop staring at the creepy vase". Olivier said, blinking confused I followed him. Yea it, was a good idea to leave, with that we left the shop. "Damn that thing was giving me bad feelings, wouldn't be surprised if it was possessed by some evil spirit, you feeling okay? It looked like that thing was trying to manipulate you".
"I… think so? It was just, I felt some kind of pull towards it, but also a repulsion. It was weird…". I felt uncomfortable, really uncomfortable. That image… why did it feel so important, but I couldn't think of anything!
"Hey, you're fine now. We're probably never going to see that thing again, it's just a creepy vase". With a pat on the head, Olivier brought me over to a restraint to have something to eat. Yea it was just a creepy vase, if it was something important, I would've heard about it in the fanfictions.
Olivier and I had a great lunch, he still shocked at how much I ate, and it's not my fault for this! I blame my Demi-Servant body. Anyway after lunch, it was finally time to begin my real training! Olivier took me away to a forest area near the town, and pulled out a suitcase from his magical storage space.
Opening the suitcase, I saw 3 item. A sword grip, a light sword, along with a gun with what I assumed to by holy bullets, and finally 3 bottles of glowing water.
"These are the basics that any exorcist usually knows how to use, but today we're just trying to see how you use them. Now there are a few things you NEED to know before we begin, a gun is not used for friendly sparing, there is no such thing as 'warning shots', if you shoot, you shoot to kill. Anyone who thinks otherwise is an idiot. A sword can be used in friendly sparing, but only if it's blunted, never use a sharp blade in a friendly match. Holy Water has a few uses, it could be purifying, or if you want to really hurt a devil, pour this onto them and they'll start screaming like a little brat". Olivier explained other deeper details on each weapon, how to use them, and how to avoid hurting myself.
We first started with the gun, which I had absolutely no skill with, no dear god I was bad with this thing. I guess Galahad's spirit couldn't help me with a gun, and Olivier had decided that training me with a gun would be better done later.
I had better luck with the sword, I was no master but I could at least do the basic moves Olivier asked me to, probably the Spirit of Galahad once again. Olivier's proud grin at me getting the basics so quickly was strange, how long had it been since someone's been proud of me?
The most interesting piece however, was Olivier teaching me some tricks with holy water, well I say tricks but more in his own words 'Fucking idiots who can't even realize you can coat your weapon in holy water'. It was weird I agreed, it was pretty simple logic, holy water hurts demonic entities, coat a holy bullet in holy water, you've got a very powerful holy attack.
"Many supernatural's are over-confident in their abilities, you'd be surprised how much they ignore a simple thing like 'logic'. Even the church who use Guns, only use one type of gun, who cares about honour in a fight to the death? Just use a sniper rifle with holy bullets, bam, you've got a dead devil. C4, guns, or grenades if modified, can work perfectly well against a supernatural". Huh, Olivier kind of reminded me of Kiritsugu with his use of modern weaponry, plus Excalibur Nightmare, he's a real monster.
It actually made me realize WHY the Church kept Olivier about, even with his dislike of them, he's just that good at his job. He's intelligent, a skilled trainer, and capable of taking down high class targets. Excalibur Nightmare's ability to cast illusions only improves all those skills.
"Hm, you've done a good job with your training so far, but it's time to finally try and unlock your Sacred Gear. I'd rather avoid the life threatening method of unlocking it, so we'll start with the simple method, think of the strongest thing you can, and focus on your desire to have some kind of similar power. Sacred Gears are driven by desire, so this should work". Olivier's explanation was a bit, weird? But I think I got it.
Taking a breath, I started thinking, what was the strongest thing I could think of? Obviously the Omni-King from Dragon Ball Super, but that felt to far, maybe something from Fate? With that thought, the image of a certain golden king entered my mind, thousands of weapons carried inside his infinite gate. But my mind was most drawn to an object in his hand, it could barely be called a sword, but its power could reduce all things to genesis.

(Oh? Finally drawing on my power are you? Such power you desire… I suppose as an entity of desire, I must approve of this… but tread carefully girl, I will not be locked away forever…)
It hurts! IT HURTS IT HURTS IT HURTS! WHY DOES IT HURT?! Falling to my knees in agony, a black smoky mist came from my body, lashing about and damaging the area. The last thing I saw before unconsciousness claimed me, was a worried Olivier rushing towards me.
A few hours later…
My body hurt… it really hurt, but my surroundings were soft. I managed to open my eyes and gazed around, I was in the RV? Letting out a groan I attempted to get up.
"Woah woah! No getting up kid, your body's been torn apart on multiple levels, you're lucky I managed to find a phenex tear in town or you'd be crippled for a few months". The voice of Olivier grabbed my attention and I turned my head towards him. He was approaching with a glass of water and offered it, which I drunk greedily.
"What happened?". My throat felt sore even with the water, but I managed to force the words out.
"Your Sacred Gear, I'm not exactly sure what it was, but when you used it, your body released a bunch of shadows that destroyed everything around them, harming your body as well. I had to rush you to a hospital, luckily they had some phenex tears from the devils living in the town". Olivier explained, a phenex tear, aren't those extremely expensive? And… Olivier brought one for me without hesitation… "Hey kid, stop with the tears, you're absolutely worth a few phenex tears".
Tears? I'm… crying? Lifting up a hand I wiped away the tears.
"Sorry I'm just… have I ever said I'm really thankful to you?". I said, and with a smile Olivier pat me on the head, it was slightly annoying but I could deal with it, it was nice…
"No need kid, no need. How about I just cook something quick and simple, and I tell you some stories about some of the missions I've gone on?". He offered, and with a nod of agreement from me he started cooking and telling me of his first encounter with a vampire.
A different pov…
She had been trapped here for so long, nothing to feed on or entertain her, however now, something new had occurred. She had felt her prison shift, and a connection form to another, what sweet emotions… however her meal wasn't ready yet, it needed to mature and taste true despair first.
Licking her red lips, she couldn't wait to turn this girl into her new vessel. That foolish deity thought her gone, but you could never erase humanity's deepest desire.
It would take time, but she had all the time in the world.
So, I'm planning for Tachie to get her own team, and I've already planned a few members. But I wanted to ask if anyone wants to suggest any ideas? Any supernatural species is allowed, including hero descendants and lot tier gods, but they need a reason why they'd actually join Tachie.
For those who feel that emotional moment was out of nowhere, Tachie may have the soul of an adult, but she's in a 13 years old body. She also almost DIED from awakening her gear, she gets an emotional moment.
For those wondering who the mysterious figure is? Well I've left enough hints for you to guess.
