"So what do you need Shiro...?" I'm now standing on the school rooftop with the girl in question. I'm also blushing a little bit, since she might try to confess her feelings for me! What should I do!? What if she's monogamous!? So many possible endings...

Shiro crosses her arms, which kinda highlights her boobs. I shouldn't be thinking that, sorry. "Are you a magus, Shibata?" Do I count as one? I don't really know any magecraft at all...

I shake my head in denial, much to her surprise. "Nope. Like I said before, I'm a Campione... Rin is a magus though! Did you know she owns this city!? I didn't think people could own cities before!" Oh well, silly me. Shiro probably knows it already, since you're supposed to ask Rin for permission to live here and all that.

Shiro looks down. "I figured she was one... Anyways." Her gaze comes back to me, and my blush returns. "So is everything you said true Shibata?" I nod, and she grits her teeth. "So what exactly is a Campione anyways?" Wow, I'm surprised she hasn't heard of the term before...

Wait that means... I'm the one with the most amount of knowledge here! Something that pretty much never happens in my life unless I'm talking about swords. I must say, I like this feeling, maybe I should pursue a know-it-all career? I could be the next Einstein...

I giggle, glad I am knowledge itself right now. "A Campione is a god slayer, I did say I killed a god right?" The girl nods. "Well, after you do so, you become super strong. That's what a Campione is." And most Campione are already strong enough to kill a god while human, so it's obvious why they're scary.

Not that this principle really applies to me. The truth is that Takemikazuchi was purposefully dragging his body down to the level of a normal human out of honor... Ah, I might be the runt of the Campione's litter, I need to kill a new god to prove my abilities or something.

Shiro looks down. "Super strong huh...?" She then mutters. "Trace on." Her body trembles a little, and her right eye twitches... Immediately she starts to sweat. It actually looks like she's having an orgasm or something, which is kind of hot, but it also kinda looks like she's in pain, which is not really that hot.

The feeling of mana is in the air, I raise an eyebrow. "So Shiro, what are you? A magus?" She could be something else, like a Campione! It would be weird if Waver didn't inform me about it, but everyone makes mistakes once in a while.

Shiro nods. "Yeah, I'm a magus... So Shibata, I have one last question to you..." Geez, why is speaking so hard for her now? She really sounds like she's in pain. "What's with the sex slave stuff?" Is she interested in the position!? I was right, she really does like me!

I awkwardly scratch my head. "Ah, it isn't too complicated. I just made some cute girls my concubines because no one can really stop me, that's also how I got rich." Well, I guess other Campione could stop me! I didn't win against Doni after all, but he was also the only Campione who contacted me thus far.

Suddenly Shiro shouts, it actually makes me step back out of surprise. "Don't you see it's wrong to do that!?" I mean... Kinda...? "You think it's okay to turn people into sex slaves just because you're stronger than them!? Think about...! Think about what other people feel for once...!" Wow, she hurt my ears. Is this because she's jealous of my concubines!?

I tilt my head in confusion. "Of course I think about what people feel! And it's not like I go out of my way to do bad stuff... I'm not a sadist you know?" I sigh. "It's just that some people are so weak, that they naturally get consumed just by me existing." Like the ant I accidentally stepped on my way to school.

Shiro gets into a fighting position...? "If you really think that... Then I'm gonna have to stop you Shibata, or at least try to." Wow! That feels really suicidal of you, but who am I to deny her invitation for a fight? Besides, I don't even know if she has tricks up her sleeve, so maybe I shouldn't underestimate her...

I grin. "Sure, feel free to try. Just be careful, nothing ruins my good mood more than a boring fight." Actually, there are a few other things that also ruin my good mood. Like if I suddenly found out I was poor! Or if Rin said she was in hospital! Or... The world is full of bad stuff.

Shiro tries punching me... And my good mood is now dead! She's painfully slow, and watching her fist slowly move it's way to my face is like watching paint dry... Actually watching paint dry is more fun than this, I know, because I have seen it before.

Honestly, she's slow that I have time to think about other stuff. Like why is she attacking me? Can't she see the clear divide between us? I guess she's unfamiliar with the term Campione, but surely I made it clear enough that I'm super strong?

Maybe it's because she's stupid? I guess I can't make fun of that. Still, her fist hasn't reached me yet, should I dodge? Oh well, at least I can watch her boobs in slow motion! They are surprisingly big, something I never actually noticed before.

Actually, Shiro's whole body is pretty hot. Probably because she's super fit due to archery stuff. I imagine that if she tried more, she could have been an idol of the school right there with Rin.

Has her fist reached me yet? Nope. Should I start doing my math homework inside of my head while I wait for her? That's probably impossible, I'm not that smart, I need a notebook to do it.

You know what? Screw this. She's clearly not built for this, and she disappointed my fighting instincts. Due to that, I shall take Sakura's advice! Sexual punishment! Well, Shiro is not really my concubine, but she could be if I wanted, so it's fine.

I move, disappearing from Shiro's vision, for her it might seem like I just teleported behind her. I analyze a very important detail of her body, her ass! It's pretty nice too, which is surprising since archery is focused on upper body strength. Does this means she works out outside of the club?

Nonetheless, I take this opportunity and give her ass a good grab, immediately she shrieks. "Shibata!? What the hell!?" She turns around as fast as she can, hoping to actually land a hit on me. The problem is that as fast as she can, means the slowest god damn thing ever for me.

Still, the feeling of her butt did make me feel better. My mood is returning to a good state, so I might as well continue my molestation... Well, it's not really molestation, I'm probably making her my concubine, which means I own her anyways.

Yet again I move behind her, this time though, I give her a hug. Except instead of being a normal hug, I'm using both of my hands to grope her tits from behind. They're big, nice and soft... All good traits! Shiro really keeps getting points in the concubine body exam...

She naturally struggles against my grip. "What are you doing!? This is a fight, stop being a pervert!" I like being a pervert though. Also your red face is super cute, definitely concubine material.

The only thing she's lacking is brains, I guess... "How is this a fight? You can't land a single hit. Hell, you can't even escape from this." It goes without saying that I have not let Shiro go free, my hands are still on her surprisingly big tits.

That said, I need to seriously think about this! My harem is growing super large already, and Waver will presumably bring a cute girl today too...! So does Shiro pass the concubine exam? The one I just made up right now?

Her strength doesn't matter, since I'm so strong. That means it's not even a part of this litte exam at all. Next up is her body, and considering I'm still groping her tits while she moans... She definitely passes! I hope she's happy about this, it must have taken a lot of hard work to get a body like this.

Next up is... her personality? I like Shiro well enough, I guess. Though I admittedly don't know much about her beyond the fact that she's super nice. Still, she passes, I'm interested in knowing more.

I smile and then release Shiro, the girl immediately turns around to glare at me. "Take this fight seriously!" She still thinks she can beat me? If I had taken this fight seriously she would have been a stain on the floor at this point.

I chuckle. "Sorry, it's just that you're weak. Like super weak. It's cute how dumb you are though! With thinking you can stop me and all!" And there it is, the most important part about adding this girl to my harem... Her lack of intelligence!

I'm obviously a dumbass, there is no denying that. However, Shiro apparently challenges me in the brain department, which means having her on my harem might make other people think that maybe I'm not so dumb after all. It's sorta like a hot guy hanging out with an ugly guy... Actually this might be more like an ugly guy hanging out with an uglier guy. Still works though!

Shiro looks down. "I... I guess it's obvious I can't beat you huh?" She looks at her own hand, and then clenches it. "I tried reinforcing myself, but I couldn't pull it off." I don't know what that means! Man, I really have to take Doni's advice already and ask Rin for magic lessons.

I wave her off. "Don't feel too bad about it. Most people can't stop me, that's why I'm a Campione!" I don't know why she thought she of all people had a chance. If I didn't know Shiro better, I would call her suicidal... Actually I don't know Shiro that much!

The girl looks down. "Damn it...! Is this really how things pan out!?" Yep, I win, I'm cool. She then comes back to glaring at me. "Someone will stop you eventually! Like John Pluto Smith!" Ah, the super hero? I wonder if I could beat him...

I make a thinking pose. "Well, it's true that I would probably lose to him." He's an experienced Campione, just like Doni, and we all know how that fight went. "He won't pick a fight with me though, because we are brothers!" Probably! At least he hasn't started trouble yet.

I imagine he probably knows what I'm doing too, it's not like I'm secretive after all. Which means the super hero must have decided it's not his problem, which is definitely something I'm grateful for! I don't need other Campione ruining my harem because they're feeling heroic or whatever.

Shiro takes a step back in shock, her face morphed in surprised. "What!? He's your brother!? Since when!?" Since I became a Campione silly! Oh right, I forgot she's totally unfamiliar with what it means to be a Demon King.

I smile, trying to make her lower her guard. "Ah, he's not actually my blood related brother. It's just that all Campione are technically related." Does that mean they're also my mom and dad's kids!? Are their parents, my parents!? Stuff like this is so confusing... I get lost even when I'm explaining it!

For some reason, Shiro hasn't stopped being shocked at all. "John Pluto Smith is a Campione!? Magic is supposed to be a secre- Ah, I guess he is a super hero..." A blush appears on her face. "But I thought he was an alien or something..." And so mystery grows ever mightier! I think, I don't really get what that means.

I shrug. "That's what most people think. Anyways, the important part here is that he won't interfere with my plans, unless I start messing up stuff in the United States of course." Which I wouldn't do! Unless someone from there insulted my harem of course, but I'm sure he would understand my actions in that case!

Shiro seems pretty sad for some reason. "So it's hopeless...? That can't be right..." She then looks down. "I guess at least you aren't killing people." Yep, the only thing I ever killed was a god! So far I haven't killed any human, and I don't plan to change that any time soon.

I pat her head, surprising her. "I'm glad you're seeing that you can't do anything at all!" If someone understands that they're weak power wise, then maybe they can find something else where they're strong. Like for example... maybe Shiro is really good at cooking! Everyone loves a cook!

For some reason she slaps my hand out of her head. "You... I used to think you were a good person Shibata. I'm disappointed to find out I was wrong..." Eh? Did I do something seriously bad? I might have done so without noticing now that I think about it.

When we first got here, I thought for sure she was about to confess to me. In the end though, we just got into a fight... if you can even call that a fight. Nonetheless, it certainly wasn't a positive outcome, and while I would like to blame Shiro for it... I should be responsible and try to see things from her perspective too.

I have to say though, understanding what's she's feeling is hard! I'm guessing jealousy is involved? Oh, I get it now! It's fairly obvious really! Here I was bragging about having a bunch of concubines to the girl that has a crush on me! It's obvious she would feel insecure and sad...

I guess I have to apologize now, so I send Shiro a confident smile. "I'm sorry I disappointed you. Don't worry, I won't let that happen again anytime soon." Hopefully she accepts my apology... though I will need to show I feel sorry through my actions too, of course.

Shiro blinks in surprise, the fact that she didn't even think I would apologize does hurt a bit, but I understand I hurt her feelings, so I just have to accept that. Throwing blame at her won't fix anything! Even if she did resort to violence really quickly... Welp, she is stupid after all, even dumber than me!

Her guard is still seemingly up. "Won't disappoint me...? Does that mean you're letting Tohsaka and the others go?" Go where? It's not like I forbid Rin of traveling around or anything, in fact I encourage! People say travelling is good for character building! Still, even if Shiro is acting weird, I'm glad now there's a bit of hope in her voice.

I close one eye and raise a hand nonchalantly, basically I'm trying to act like a cool anime character in front of the girl who might like me. "I never forbid them from traveling in the first place." Shiro then sends me an awkward smile in return, seemingly lost.

Then I make a thinking pose. "By the way Shiro... Do you have any hobbies outside of archery?" I'm trying to find out more about my soon to be concubine. Also I should try to see if she's talented at anything besides archery.

Shiro's mouth is open, she really looks dumb. Specially since she's looking at me like I'm an alien. Still she answers the question eventually. "Um... I'm good at cooking?" I knew she had a chef aura around her! See, even weaklings can be strong in their own ways! That's why life is beautiful.

I nod to myself. "Man, I have an eye for talent. Okay Shiro, what is your dream? Please answer honestly, and be aware I won't judge you for it." I might have to crush it too! If it's not related to either cooking or archery.

Suddenly Shiro chuckles. "How did we get here? Honestly you..." Ah, she didn't answer my question this time. Honestly how did she already forgot how we got here anyways? I think her stupidity might be a treat for her own life.

Oh well, stupid girls are both cute, and make me feel smarter. I have to answer her question though, hopefully she won't forget it again. "We walked here. You took me by my hand remember? Like a guide." A very dumb guy apparently. Scary, did she even know where we were going?

A slight smile appears on her face. "A guide huh...? I wonder, what would Fuji-Nee do with super powers?" Fujimura-Sensei? Probably force some guy into dating her. "She would probably force some guy into dating her." We are in synch! My apology really did wonders.

Still, there is something I'm curious about. "Hey Shiro, aren't you dating Fujimura-Sensei? Would you really be okay if she got a boyfriend?" I guess I can't talk, since I'm just expecting all my concubines to accept the harem plan... But they are concubines after all. Shiro is presumably just dating her.

For a moment her face goes green, quickly she goes back to normal. "I'm not dating Fuji-Nee, seriously Shibata, I would rather die." What a plot twist! But you guys should have seriously made things clear, it confused me!

Shiro then shakes her head. "But this is not the time for that." There's a fire in her eyes... Actually, it's something else, I shouldn't think about fire when it's related to Shiro. "My dream is to be a hero of justice Yato." She called me Yato!

The girl looks to the skies. "You're a bad person." Eh!? A sudden insult!? "But you're not exactly smart, so I can't blame you..." Another insult!? And from you of all people!? "I can't stop you either, you're obviously miles ahead of me..." The girl ends with a sigh.

But then a smile appears on her face. "But heroism is not always about beating the bad guy, sometimes talking is enough. From now on Yato, I'll be your guide, I will try my best to contain your urges." Just like Caren! Does she also want me to impregnate young girls!?

I pat Shiro's shoulder. "Thanks, I'll be counting on you." I won't, she's clearly stupid! There's no way she can be a good guide! "By the way, you're hot, so I'm making you my concubine. Yep, you're my sex slave now." Another one joins the club!

Shiro's face immediately goes red. "Eh!? T-that's...!" Awww, how adorable, she must be elated! That's right Shiro Emiya, you are now my concubine! Even if you're dream doesn't really relate to your real talents, and so I might have to crush it one day.

The bell rings, it's time to come back to class. "Let's head back Shiro... Learning awaits!" I hate learning... and yet I must learn nonetheless. Truly this world constantly shifts between scary and beautiful.

As I rush to class, I hear a blushing Shiro muttering. "I can fix him, I can definitely fix him..." fix what? I'm not broken. Silly, dumb Shiro...


AN: And so Shiro finds an objective even harder than becoming a hero of justice... Turning Yato into a decent person!

Also very important information, I decided to give Shiro big boobs. I always imagine her as Gudako in my head, but Gudako's tit size is actually fairly inconsistent between her mystic codes. She shifts from flat, to normal, to big all the time.

Big good though, so I went with big. Very cool.
