Genetics doesn't work like that.

Dr Romani looked at the paper and then looked at Ritsuka. "Your blood type is still the same"

Ritsuka noded, his long red hair tited back to the a pong tail. "Ok that solves that"

Dr Romani then looked at him. "And you said you have this layer or skin in your eyes that goes away when when you use your mystic eyes of death and comes back when you turn it off"

Ritsuka just nodded looking at him. "Yeah about right"

Dr Romani just then looked back the paper. "And you can breathe fire thanks I being a dragon... I think that is how genetic work, at all"

Ritsuka chuckled softly, running a hand through his long red hair. "Yeah, I guess that part is a little weird, but considering everything that's happened, it's the least strange thing about me now."

Dr Romani sighed, setting the paper down. "I mean, it defies everything we know about genetics. Being a dragon, having godlike powers, breathing fire... It's like you've become some kind of mythical creature in human form. It just doesn't line up with basic biology."

Ritsuka shrugged, a playful smile on his face. "Welcome to Chaldea, where normal human limits don't really apply anymore. Might as well embrace the chaos."

Romani rubbed his temples, clearly trying to make sense of it all. "I know, but still... you'd think there would be some rules that even the universe wouldn't break."

Ritsuka glanced out the window, deep in thought. "Maybe the rules are just different for me now. Between the gods, dragons, and everything else, I'm not sure I count as just human anymore."

Dr Romani sighed again, though there was a smile tugging at the corner of his lips. "Well, whatever you are, at least you're still the same Ritsuka. Just... with a few extra 'features.'"

Ritsuka chuckled. "Yeah, just a few."

With that, the atmosphere lightened, though the strange reality of Ritsuka's evolving nature lingered in the air.

Dr Romani just looked at him. "And then it is your dragon transformation, I am not even gonna try and make sense of that, but now you can eat almost everything"

Ritsuka just looked at the good doctor. "Almost?"

Dr Romani just looked at and a sigehd. "Almost"

Ritsuka raised an eyebrow, crossing his arms. "What's the almost part? What can't I eat?"

Dr Romani, clearly exhausted from trying to rationalize Ritsuka's new physiology, rubbed his temples. "Well, it's not like I can say definitively, but based on your current state, it seems you can handle most things—metal, fire, probably even some magical substances—but there's always a limit. There's always something out there that your body might reject or struggle with."

Ritsuka chuckled. "So, you're saying if I eat some kind of cosmic poison, I might have a bad day?"

Romani gave him a tired look. "Exactly. Let's try to avoid testing that theory, though. Your body might be adaptable, but you're not invincible."

Ritsuka shrugged with a grin. "Noted. I'll stick to less questionable foods for now, then. I don't need another excuse to end up in the medical bay."

Dr Romani sighed again, shaking his head. "Please don't. You've already given me enough work as it is."

Ritsuka smiled as he stood up. "Alright, I'll keep the experimental meals to a minimum."

Da Vinci finkat spoke. "Let's get with the big Question, if you have a child with one of Tory harem member.... How would that work, can't try even get pregnant"

Kama then spoke. "Me and Morgan yes, Gods like me and Fairy like Morgan can have kids with anything"

Ritsuka froze for a second, his face flushing red at Da Vinci's rather direct question. He scratched the back of his head awkwardly, trying to avoid eye contact with anyone. "Uh, that's...a bit out of nowhere, Da Vinci."

Da Vinci smirked, clearly enjoying his reaction. "Hey, I'm just being scientific. With your new dragon and god status, we're all curious how that would affect, well, certain... things."

Kama leaned back, a mischievous smile on her face. "Like I said, gods like me and Morgan can have kids with anything. No barriers when it comes to divine bloodlines. In fact, if I ever wanted to, well..." She winked at Ritsuka. "We'd make quite the powerful offspring."

Morgan nodded calmly, adding with her usual regal tone, "Yes, as a Fairy Queen, it's within my nature to bear children with a variety of beings, even gods or dragons like yourself. It would certainly be a unique lineage, but entirely possible."

Ritsuka, still flustered, stammered. "W-Wait, I'm not... I mean, we haven't even—"

Kama cut him off, laughing. "Oh, don't worry, Master. No one's asking for kids right now. We're just making sure you know the possibilities. And, well, you do have quite a large harem, so it's bound to come up."

Dr Romani, who was clearly trying to remain professional, looked like he wanted to be anywhere else at the moment. He cleared his throat. "Right... uh... this is definitely a hypothetical, right? No one's rushing into anything here?"

Da Vinci smirked, looking like she was about to tease Ritsuka further. "For now. But it's good to have all the facts, wouldn't you agree, Ritsuka?"

Ritsuka just sighed, knowing there was no escaping this conversation. "Yeah, facts are great..."

Kadoc then looked at Ophelia and Mash. "So what about the Actual Humans, I mean Mash is a demi servant so I don't have any idea".

Dr Romani and Da Vinci went silent. "Um about that"

Ritsuka looked at Him. "I don't like the way you guys said it"

Da Vinci just looked away embraced. "Do to un.... How Mash was made by Chaldea, she can have kids with.... All Fantastical beast including people like you Ritsuka"

Da Vinci awkwardly cleared her throat, still avoiding eye contact. "So, uh, Mash can... well, she's compatible with a wide range of beings. Including people like you, Ritsuka."

Ritsuka's face turned even redder, as he glanced over at Mash, who had been sitting quietly, her hands fidgeting in her lap. She looked equally embarrassed, her cheeks flushing pink as she avoided Ritsuka's gaze.

Ophelia raised an eyebrow. "Wait, are you saying that because of how Mash was created by Chaldea, she's... well, capable of having children with not just humans but... fantastical beings? Like, dragons or gods?"

Dr Romani nodded, though he looked extremely uncomfortable. "Yes, exactly. Mash was created as a Demi-Servant, but with the magical enhancements that were... well, let's just say Chaldea didn't exactly anticipate this particular scenario. Her biology, while mostly human, has certain... allowances that make her compatible with beings beyond normal humans. You, Ritsuka, being part dragon and god now, fall into that category."

Ritsuka blinked in surprise, looking between Mash and Dr Romani. "Wait, so you're saying... Mash and I... could...?"

Mash finally looked up, her voice quiet but firm. "Yes, Senpai. I... I wasn't sure if it would ever be relevant, but after everything we've been through, and your transformations... it seems I could, um... well, bear children with someone like you. It's... strange, but true."

Ritsuka was speechless. He hadn't expected this turn of events at all, and the thought of children with Mash, or anyone in his harem for that matter, hadn't even crossed his mind. It was too much to process all at once.

Kadoc, of course, wasn't going to let it go so easily. "So, what you're saying is... you've got a harem full of beings, gods, fairies, even humans like Mash who can all have kids with you? That's... quite the situation, Ritsuka."

Kama smirked. "Seems our Master has more options than even he realized."

Da Vinci rubbed the back of her neck, clearly embarrassed by the conversation but pressing forward for scientific clarity. "It's not just Mash, Ritsuka. If a human has been exposed to enough magical or divine energy, their biology can change too. Ophelia, for example—well, considering her unique situation, especially with her Mystic Eye, it's very possible she might have the same... potential."

Ophelia, who had been quiet until now, shot Da Vinci a sharp look. "Wait, what? Are you saying I could also...?"

Da Vinci nodded. "Yes, given your connection to the supernatural through your Mystic Eye and the magical enhancements you've endured. It's not exactly the same as Mash, but... you might have more in common with her than you think."

Ophelia's face flushed, and she crossed her arms, clearly deep in thought. "I... didn't expect this conversation today."

Ritsuka sighed, rubbing his temples. "None of us did, Ophelia."

Dr Romani interjected with a serious tone, "Look, we're not saying this is something that needs to be decided right now, but... given your new status, Ritsuka, it's something we needed to be upfront about. We don't know what kind of future you're going to have, and these... biological realities could come into play eventually. Whether you're ready for that or not."

Kama leaned closer to Ritsuka, her voice teasing but sincere. "Don't worry, Master. We'll make sure you're well taken care of, no matter what. But you should be aware that with your current abilities and divine nature, the line between mortal and immortal... it's a little blurry."

Ritsuka shook his head, still processing everything. "So, basically, any of you could... have kids with me, regardless of whether you're human, god, or something else. And Mash, even though she's a Demi-Servant... she falls into that category too."

Dr Romani nodded, his expression one of resignation. "Yes, Ritsuka. That's... exactly it."

Kadoc, leaning back in his chair with a smirk, muttered under his breath, "Looks like you've got your hands full, Fujimaru."

Mash fidgeted again, her blush deepening as she murmured, "Master... I just want to say... no matter what, I'll stand by your side. This... this doesn't change anything about my loyalty or feelings for you."

Ophelia, still looking a little stunned, nodded in agreement. "Same here. This doesn't change how I feel either. But... it is something to think about."

Ritsuka gave them both a small, appreciative smile. "Thanks, both of you. I didn't expect any of this, but... I'll do my best to figure it all out."

Da Vinci, trying to lighten the mood, clapped her hands together. "Well, now that we've had this fascinating and slightly awkward talk about genetics, I think we can wrap things up here. No need to rush into anything. Let's just focus on the Lostbelts and saving humanity, shall we?"

Ritsuka nodded, grateful for the change of subject. "Yeah... let's stick with that for now."

Kadoc just sigehd. "I am going to make this awkward... What about BB, Koyanskaya, Olga, Marie Alter".

Marie alter cane out of Ritsuka Shadow, BB then came out Ritsuka mind, as they gave there answers as Kadoc blinked

Kadoc scratched his head and sighed again. "So basically, it seems like almost everyone has some way to make it work." He rubbed his temples, clearly overwhelmed by the complexity of the situation. "This is way more information than I bargained for."

Ritsuka glanced around at the group of women surrounding him, each offering a unique explanation for their compatibility. He couldn't help but feel a bit overwhelmed himself, though there was an undeniable warmth in knowing they were all willing to share this with him.

Marie Alter folded her arms. "Like I said, it's a 50/50 with me. I exist as one of Ritsuka's Umbra Summons, so there's some servant in me, but the rest? It's up in the air."

BB smiled slyly. "Oh, you don't need to worry about me, Master. If you ever want to... test things out, the Moon Cell's got me covered. I can rewrite my coding as necessary. It's part of the perks of being a super AI."

Olga, on the other hand, just shrugged again, clearly indifferent. "I have no clue".

Ereshkigal chimed in with a calm, authoritative tone. "I'm like Kama. As a god, I have the ability to bear children regardless of who the father is. My divine heritage ensures that much."

All eyes turned to Koyanskaya, who was leaning against the wall with a smirk. "You all seem surprised. I'm essentially a spirit created from the death of the animals in the Tunguska event, infused with my own brand of magic. So, similar to Morgan, I can definitely have kids with beings like Ritsuka, especially considering my spiritual makeup. But unlike most of you, I don't need to." She winked playfully at Ritsuka, making it clear that she enjoyed keeping her options open.

Ritsuka, feeling a bit flustered, put his hand to his head. "Okay, okay... this is a lot to take in." He turned to Kadoc, who was clearly enjoying the awkwardness. "Kadoc, you're really not helping here."

Kadoc grinned. "I just thought it was time to ask the hard questions."

Da Vinci laughed, clearly amused by the situation. "Well, we're all about solving mysteries here at Chaldea, and this one's no different. But, for now, let's focus on our immediate mission. Saving the world takes precedence over starting families, right?"

Ritsuka nodded, relieved to move the conversation along. "Yeah... saving the world first, everything else can come later."

BB gave a teasing smile. "Don't think you're off the hook that easily, Master. We'll have to revisit this conversation eventually."

As the others began to relax, the tension in the air lifted. Despite the strange and uncomfortable topic, there was a sense of camaraderie among the group. They were all bound together, not just by their mission to save humanity, but by their unspoken loyalty and affection for Ritsuka.

Mash, who had been silent for most of the conversation, finally spoke up. "No matter what happens, Master, we'll all stand by your side." She smiled softly, her embarrassment fading. "We'll figure everything out together."

Ritsuka smiled back at her. "Thanks, Mash. I know we will."

And with that, the heavy conversation came to a close, leaving them all with a deeper understanding of their bond and the unique circumstances they found themselves in.
