The Shielder of DxD

[EclipsingDragonMoon]

So I like making Omakes, so here's an omake!

Ritsuka stared at the new Servant, he had been investigating this Singularity and been separated from Mash. However even he was confused how in the world this had happened!

"How many times do I have to tell you? No I'm not Mash Alter! My name is Tachie! TACHIE!". The black-haired red eyed version of Mash shouted at him. Her outfit wasn't a perfect match for Mash, more a skin-tight suit then the armour Mash wore, but the weapon in her hands was without a doubt Lord Camelot.

"How do you have Lord Camelot then?". Ritsuka asked, confused why this girl who was clearly a version of Mash, kept denying it. Da Vinci had even confirmed her spirit origin was exactly the same as Mash!

"Because I'm the Demi-Servant of Galahad? Not my fault that stingy bastard won't give me any swords!". Tachie replied, she was the Demi-Servant of Galahad? This was starting to give Ritsuka a headache, this girl was a perfect match for all the information details of Mash. So somehow she was ether a perfect but alternate copy of Mash, or she was Mash with modified memories and appearance?

The 2 had meet a few minutes ago, with Ritsuka rushing towards her and giving her a hug, exclaiming how thrilled he was to find her again, only for Tachie to punch him and start shouting about not touching her and demanding who he was. Da Vinci had tried figuring it out, but from her Spirit Origin to her appearance, she was a perfect but alternate version of Mash, the Universal Genius had suggested perhaps Mash had been transformed into Tachie by some type of corruption.

"Mas- Tachie, are you sure the name Mash isn't familiar to you?". Ritsuka said, perhaps it was better to try subtler methods of figuring Tachie out.

"I will admit it sounds… familiar. But I can tell you with 100% conviction, I have never met anyone with that name". Tachie admitted. So Tachie found Mash's name familiar, but was convinced she'd never met anyone with it? Well you can't meet yourself (Unless you're a Heroic Spirit), so that did make sense.

"Tachie, could we speak to Ritsuka privately for a few moments?". Da Vinci asked, with Tachie nodding in agreement and walking further away. "As much as it pains to admit, Tachie's existence confuses me. Her class is Shielder, her Spirit Origin is a perfect match for Mash, and her appearance besides a few details is a perfect match. I'd say she's an Alter, but she's too similar to be an Alter! But she may be able to lead you to answers, you have no other Servants with you and she seems just as powerful as Mash. So just try solving the Singularity with her, and hope we can figure it out".

As worried as Ritsuka was for Mash, he had to agree with Da Vinci. He still thought Tachie was Mash in Alter form, but clearly the girl was getting angry with him using the name Mash Alter, so it was best to just call her Tachie.

Meanwhile Tachie was wondering what in the world she had done, to somehow end up in Fate/Grand Order, and where the hell was Mash?!

Tachie was strange, that was something Ritsuka found out in the first few hours of knowing her. She wasn't as passive as Mash, if anything she was far more aggressive, she didn't feel like a Shielder Servant. The way she wielded Lord Camelot was different as well, she seemed… inexperienced with it? Yea that was the best word for this. The Last Master of Humanity had seen many fighters, and Tachie seemed more a swordsman than a shield user.

"Hey Tachie, are you… Used to Lord Camelot? You don't seem to be experienced with it". Ritsuka eventually asked, with Tachie turning to glare at him. Sheesh, why did she seem to be so angry? It seemed like she had a personal issue with him. Her expression softened, trying to hide her anger, but if there was anything Ritsuka was really good at, it was reading people (But he couldn't realize half the females of Chaldea were madly in love with him, including his kouhai).

"I am more experienced with a sword and a gun, I… only got this shield when I was summoned, but I am aware of its powers and abilities". Tachie replied, a gun and sword combo? That was unusual. Mash didn't have experience with guns (Why did he get a bad feeling from those words?), but she was surprisingly skilled with a sword, something Lancelot had only been too eager to help her with.

Ritsuka still wasn't sure exactly what Tachie was, was she a corrupted Mash? Was she a Mash from an alternate timeline? Or did she have absolutely nothing to do with Mash? It was beyond confusing for the master.

Another thing to note was Tachie's refusal to enter a contract, she was clearly starting to run low on mana but refused even a temporary contract with Ritsuka. The Shielder had insisted she'd be fine, but he doubted that.

He wanted to help, but Tachie just refused any attempts, how could he help someone who didn't WANT his help?

Things weren't easy on Tachie's side ether, before this entire mess started she was on a mission with, ugh, Issei and Vali (Why did Azazel put the 3 of them together? She hated working with them both), and after a blinding flash of light while fighting some magicians, she woke up here as a Servant!

Meeting Ritsuka had been weird, her head felt woozy. She also kept having flashback to memories that weren't hers, of spending time in Chaldea and talking to Doctor Roman and Da Vinci, of spending time with Senpai… these were Mash's memories and it was worrying Tachie. Was this some sort of bleed over effect similar to what happened with Shirou and EMIYA? But Mash was nowhere about! It's also why she refused entering a contract with Ritsuka, what if entering a contract with him made these flashbacks worst?

But Tachie knew, she needed mana and she needed it soon. What would happen if she ran out of mana? Would she turn back to her non Servant form? Would she… disappear? She wasn't in the Throne of Heroes, Alaya didn't exist in her world. Maybe she'd return to her world, this all being a bad dream… but Tachie wouldn't take that risk.

However both Tachie and Ritsuka would have to worry another day, for their time of peace was over.

"Ritsuka! We're detecting 3 Shadow Servants! Prepare for combat". The voice of Da Vinci over the communicators startled them both into action. Without even realizing it, Ritsuka slipped into the mind-set of fighting with Mash.

"Tachie, ready yourself. We have no idea what Classes we're dealing with, so be careful!". Ritsuka explained, Tachie nodding along, struggling to avoid saying 'Yes Senpai!', those were Mash's traits not Tachie's.

"Ready for combat, please stay behind me Ritsuka". Tachie said, and with that they would begin their first battle together, trying to solve the mystery of this Singularity and what had happened to Mash.

"HIYAAAAAH!". Tachie screamed as she slammed her shield into the final Shadow Servant, after it faded away she took a few seconds to gasp for breath.

"Mas- Tachie! Are you okay?". Ritsuka asked, running up to her. Both ignored his almost calling her Mash… again (It had occurred at least 3 times during Tachie's fight against the Shadow Servants).

"F-fine just… low on mana…". Tachie gasped, Servants were unlike anything she had fought before and her lowering mana hadn't helped.

Ritsuka wanted to offer her a contract again, but he knew at this point Tachie would refuse for reasons unknown to him. So he quickly thought of a plan, aiming his hand with command seals at her, he activated the mystic code.

"First Aid!". The Chaldea Mystic Code had 3 spells built into it, First Aid, Momentary Reinforcement and Emergency Evasion. As First Aid was essentially just pumping mana into a Servant to let them heal faster, using it on Tachie would restore her mana.

Tachie let out a sigh of relief, her strength restored.

"Thanks". She told Ritsuka, who just smiled at the fact she was okay now.

"Well you 2 did well!". The voice of Da Vinci from Ritsuka's communicator was heard. "And I've got good news! We've managed to fully scan Tachie's Spirit Origin, which while at first seemed to be a perfect match for Mash, we've manged to find some differences".

Tachie frowned at the idea of her Spirit Origin being so similar to Mash's, but she had a good idea what skills would be different.

Ritsuka however was busy checking Tachie's Spirit Origin.

Ritsuka's froze, Beast VI!? It had cursed Tachie, a curse so bad it had seeped into her Spirit Origin?! As he look at Tachie, he saw she was looking at him with a confused expression, likely wondering why he was so shocked. Did she have no idea what was in her Spirit Origin? How would she react if he told her?

That was even ignoring the fact she had a second Noble Phantasm that they had no idea of, Ritsuka quickly made a choice.

"Huh, this really is similar to Mash's different parameters and a skill called 'Inherited Legacy', but I can see why your Spirit Origin was so hard to tell from Mash's". He lied, Ritsuka had no way to stop Tachie if she attacked him and no Servant to defend him if she left. He didn't like lying to someone who reminded him so much of Mash, but this was a dangerous situation.

"Oh, I thought it'd… never mind. Does it help you have a better idea how to use me?". She asked, Ritsuka's almost gasped at her wording, was she doing that on purpose?!

"Y-yea! So let's head out!". He stammered red faced, speed walking away.

Tachie just followed behind slowly, Ritsuka was NOT good at lying or hiding things. But considering he likely had an idea of her connection to Draco now, she'd let him think he had tricked her, even if she'd prefer he trusted her.

This really was just one big mess.

Ritsuka breathed heavily as Tachie tied a bandage around his knee, he had scrapped it rather badly during against some Demonic Beasts. Thankfully he had started carrying medical supplies ever since he had started randomly appearing in Singularities during his sleep (Thanks to the fact his uniform always appeared with him, even when it was damaged or something new had been added).

Tachie had also apparently been trained in medical techniques (By an angel of all things! He was really starting to get curious about her world), so he'd be fine in a few hours.

"As long as you don't put too much pressure on the leg, you should be fine. If we need to run, I'll carry you". Tachie said with an embarrassed look, she'd rather not carry Ritsuka but if she had to choose between that and Ritsuka dying, it was an easy pick.

"Thanks, you're a pretty amazing Servant. You've learned how to fight with that shield really fast". Ritsuka complimented with a smile, standing up with a bit of effort. Tachie smiled back with pink cheeks (While mentally asking why she was so embarrassed with such a small compliment, she's fought naked yet THIS is what embarrasses her?).

"No problem, now let's get back to searching for that Servant signature". Tachie said, earlier Da Vinci had detected a Servant signature, likely an Assassin with how they kept disappearing and reappearing. They had ran into the Demonic Beasts while searching for said Assassin.

"Alright, let's go!". Ritsuka agreed with a smile, he had found himself enjoying Tachie's company more. She wasn't bright and positive like Mash, she was very straight forward and secretive, but she had been kind and had a very strict sense of honor.

They walked through the area, eventually coming across something neither expected.

"…Ritsuka, is that a ramen shop?". Tachie asked with wide eyes, unable to believe what she was seeing.

"Yep… and I recognize the girl ordering everything". Ritsuka sighed, so this was one of those sort of Events? He walked over to the Ramen Shop and listened to the Servant talking.

"Eeeh!? What do you mean my Space-Bucks coupon doesn't work? It's valid everywhere else!" The blond Assassin demanded, waving her coupon in the face of the store owner.

"I don't know who you're trying to fool here young lady! That coupon is three weeks out of date!". The store owner replied.
Ritsuka and Tachie just watched the two argue, one with a weak smile on his face and the other with an expression of absolute confusion.

"She's… not very bright, is she?". Tachie said, with Ritsuka slowly nodding before walking over.

"Don't worry, I can pay for this MHX". Ritsuka smiled at Mysterious Heroine X, who blinked confused and then smiled.
