Getting Issei's arm addressed... After Raynare and Azazel address one more thing.

Raynare and Azazel were heading out, when Azazel paused. "Actually, I should probably cast a little spell that counteracts mind manipulations on you before we part ways," he mused to Raynare, who stopped misstep just outside the cafe.

"...why?" she asked him a bit apprehensively. "You don't think I'm compromised in some way, do you?"

He shook his head. "No, it's just in case you did see or hear something you weren't meant to, and had your memories suppressed, or some other shenanigans," he replied. "We're literally using a basic perception filter spell to avoid casual eavesdroppers right now, so who's to say they haven't done something similar regarding you, and what you might perceive? And yes, I know they'd need more powerful means than should be at their disposal to do such a thing to a Fallen Angel without them noticing, but given the whole Asia thing, we shouldn't assume what they can or can't do."

Raynare grimaced and nodded. "Ugh, when you put it like that, it's more likely then I care to admit..." Azazel led her to an alley, and performed several incantations, and placed a hand on her head.

"... anything new you're recalling?" Azazel asked, retracting a hand, and Raynare thought for a moment, before shaking her head, even as she wracked her brain for any memories she didn't have access to before.

"Can't say I do. I'm just sorting through every recollection I got interacting with them, including those of that two week..." she froze suddenly, as, despite not having any outright new memories, she suddenly had the ability to register something that should have been way more obvious, yet, somehow, didn't notice. "What the fuck!? That wasn't two weeks! That was closer to five and change!" she exclaimed, checking the date on her phone. "...yet, the date's consistent with two weeks... Just... What!?"

"...time dilation, and yet you weren't able to count the days in any way that contradicted the amount of time that should have passed..." Azazel mused, rubbing his chin, slightly unnerved. "That's definitely something that should be outside their means. Don't confront them with it, not yet. We'll just note it for now."

Raynare nodded, before walking off. Just... Just how powerful was Rias Gremory?

...

"So, how does it feel?" Rias asked as Issei flexed his left arm back at the Occult Research Club. He had just made the wish to be able to disguise it at will, so it looked fully human now.

"...kind of... Off," he admitted. "Like wearing a long sleeve and a glove over it, made with slightly scratchy fabrics..." Experimentally, he focused, and his arm shifted back into dragon mode. "...yep, it definitely feels more right like this..."

"That's not surprising. Draconic is now that arm's natural state," Akeno nodded sagely, crossing her arms. "Wearing magical disguises can take some getting used to. So you're probably going to be having the arm in dragon form whenever you're in private, at least for a while. You're still lucky to have Rias though. The only spells we had that could address that with otherwise would basically just lock the arm into looking human, and need reapplying every few days, you wouldn't have the option to swap forms at a whim. And honestly, I think the dragon arm, while inconvenient, is hot," she added with a saucy wink. Issei flushed, before examining his arm again.

"Damn... I'm either going to have to learn to scratch itches solely with my right hand from now on, to make sure no accidents happen while my left is like this, or learn to live without my skin," he snorted. "These damn claws are sharp!"

"Maybe wish for an enchantment on them that makes them only cut something if you want them to?" Kiba suggested. When everyone looked at him, he plowed on with a flush, "And the sexual justification being... Well, wanting to have sex with it like that without running the risk of raking the girl you happen to be with."

"... that's... A good idea actually," Issei agreed. "Rias, I wish for that!" When Rias snapped her fingers, he tested it by scratching at his cheek with the claws. Nothing, no blood drawn or flesh removed. "Sweet!"
