Thank you Bestboi for the boost of confidence.
To answer you, AsashiTheInari: It's not headstrong, it's concern and cautious. Think the situation like this: If you have a powerhouse that's stronger than Yukari in Gensokyo, you need to be cautious of him. And when you saw Aya's news spilling out about HIM being your friend's FATHER, of all things, you would definitely be suspicious. Since everything is possible, it could be him controlling your friend saying so. And, Aya didn't hear everything from the conversation, just the part when Kuro declared about his relationship with Reimu. Following that logic, and you will understand both Alice and Marisa's reactions.
With that out of the way, enjoy chapter 6!
"I know that you are suspicious, but is threatening him with Master Spark and dolls necessary?" Reimu has ordered everyone to sit in the kotatsu and heads out to fill up some tea. Kuro planned to ask to help her, but since her friends were glaring daggers at him, he decided to close his mouth since any words could backfire on him. Then, when Reimu's out of sights, Marisa pulled her Hakkero and pointed it right at his face, while Alice called out her dolls and let them point their weapons, from spears to swords, to him. When the dolls closed in, he leaned back a bit in discomfort, while trying his best to keep his face straight. Thankfully, it didn't take too long before the maiden came back and scolded them.
"Are you even listening to yourself, Reimu? This man clearly did something to you!" Marisa slams her free hand on the kotatsu while not lowering her weapon. "And you even admitted that he's your father? What the hell made you believe that?"
The maiden sighs, and she starts sitting down and gives teacups to her friends and Kuro, the latter only dares nod slightly to acknowledge her action. "You two know me well, right? Anyone who dared mess with me always got themselves beaten up by myself."
"He proved himself to be very dangerous by cursing Yukari, Reimu." Alice is extremely cautious, since the dolls' weapons are directly poking Kuro's skin. "Who knows what he could do to…"
"If he is evil, he would just make us submit to him, right?" Reimu counters, then takes a small sip. "Besides, I found the proof…"
"Show us then." Marisa immediately orders.
Reimu nods and pulls out the box from the last night, puts it on the surface of the kotatsu… "Um, what's the password again?"
"Not necessary. The password was just my fingerprints. You're free to open it from now on." Kuro says, before shutting up as Shanghai pushes the spear closer…
"You're not allowed to speak here." Alice threatens.
"Jeez Alice, calm down." Reimu shakes her head disappointingly, before casually flipping the box open and pulling out the pictures from before. She then gives it to Marisa and Alice. "Here, see for yourself."
The two magicians take a quick glance to the pictures… before picking them up by themselves and observing them carefully with their eyes widen in shock. The two try to find if there's any traces of magic in these pictures, and end up with nothing. After a few minutes of checking, Marisa shouts in shock: "Impossible! There must be some tricks in here!"
Alice, once confident that she would be able to 'find the truth', is speechless this time, as the pictures in her hands are perfect evidences for the person she's 'interrogating'. She looks up and down multiple times, just to make sure that the faces are right. "This… this can't be right… how?"
"If you two retract the weapons and calm down, I will tell you what I know." Kuro proposes, while not moving at all.
The two magicians focus on his face for a few seconds, before Alice calls back her dolls and Marisa lowers her Hakkero. The former then orders: "Speak."
"Thank you." Kuro straightens his back and puts his hand on one of the pictures. "I'm sure you're familiar with the term 'time-travel', yes?"
"Well… if you remember the silver-hair maid." Alice says. "She's able to manipulate Time."
"And this is the proof that I'm going to do what I just said. In this future, I have to go back to the past and…well, you can see here."
"…Damn, I forgot that." Marisa facepalms herself. "But, most of the time we saw Sakuya stopping time more than rewinding it…"
"It depends on the limit of the person's power as well." Kuro says with his knowledge. "A student of mine from Outside World managed to build a time machine, but it broke when she jumped back about a century to the past, and after that she could jump back a week at best."
"Aside from that, do you two now believe him to be my father?" Reimu then concludes.
"…My apology, mister Kuro." Alice bows apologetically, with Shanghai following her gesture. "But, you have to understand that…"
"I do. Having an individual that surpasses Yukari's power in here then making a fuss on newspaper like that caused you to be cautious of me. I don't hate you, in fact, I should thank you two for being concerned of Reimu." Kuro bows gracefully.
A small silence… then Marisa laughs, surprising Kuro a little. "Well then, sorry mister! Guess we're a bit too paranoid."
"Speaking of which, am I even counted as half-Youkai?" Reimu then asks, gaining everyone's attention. "I mean, with you having wings…"
"Wait, he has wings?" Marisa looks after Kuro's back…
"Those are not real deal." Kuro reveals. "Those are parts of my battle gears. Of course, I do have it configured so it looks appeal to people."
"But, that doesn't mean you're not Youkai." Alice says. She then remembers one thing: "Change of subject for a moment. How did you get the nickname Queen of Annihilation?"
Kuro doesn't answer immediately, instead he facepalms while his face heats up a bit. "Urgh, how did you find out that fast?"
"It's on the newspapers."
"…It must be a very old one… Of course, only Anonydeath would collect them and keep it that long…"
"Who's Anonydeath?" Taking a sip from her cup, Marisa asks once hearing the unfamiliar name.
"It's Rinnosuke." Reimu reveals, causing Marisa to 'comically spit out her tea'. "It's something related to my father…"
"And I would like to not talk about it for now." Then, a light engulfs Kuro, causing the girls to raise her arms up to cover their eyes. Once it's gone, they put down their arms… "As for that title, this is the reason."
The next reactions are as followed: Reimu narrows her eyes in disdain, Alice and Shanghai cover their mouths in shock, and Marisa bursts out laughing while pointing to 'her' and says: "HOLY SH!T! Now THAT'S quality stuff right there!"
The person blushes up in embarrassment. "Please, I don't like using this form if I could help it."
"…Father, really?" The shrine maiden now starts to question if her choice to accept him being her father is correct.
"When you talk to your aunts, you will see my pain." The person then turns back to his normal form. "That aside, it's because I did a few time-travelling to the past before, and some of them involved me using the form to avoid suspicions of the present."
After laughing is done, Marisa still keeps her smile while saying: "Okay, I can see why, but that's just hilarious."
Kuro sighs. "Yeah, I know…"
"Wait a second, mister Kuro… did you just say 'your aunts'?" Alice interrupts, referencing to what he just said to Reimu.
"Yeah, why?"
"So? He told me he has a sister. I'm sure he…"
"Reimu, it's plural."
"…" After hearing that, she turns to Kuro with a suspicious glare…
"Would you believe this centuries-old me to say your mother being the first love?" Kuro sends back a blank stare.
"…I suppose I won't." Thinking about it for a moment, Reimu decides to accept that. "But, if that's the case…"
"They're still in their prime. I'm being old is because I have to jump through times and space constantly."
"Hm… sounds tough."
"It is."
"Why exactly did you have to do so?" Marisa questions. "I mean, you could just…"
"My power didn't come for free. My job is to travel through universe and help whoever I can and try to direct the world into the best timeline as possible."
"U…Universe?" All three ask at once.
"Of course I couldn't say much last night, you know that I was planning to not show my true self yet. However, given by the info I got from Komeiji sisters, I could tell there's something off."
"…Now I think about it." Alice says. "You seem to know us too well, even the young ones. Could it be…"
"Yeah, there are multiple Gensokyos." Kuro reveals. "Of course, I wasn't planning to really interfere in any of them, since you girls were already having everything under control. However, the presence of the copies here have my concern. And Yukari did invite me, so I couldn't turn her down."
"And it led you into an adventure into the past…"
"I wouldn't count that as an adventure, Reimu. Still, at least I find something worth for all the troubles." He then puts his hand on hers with a smile.
That action makes the maiden blush up a bit, both in happiness and a little embarrassment. Meanwhile, Marisa snickers when she sees her friend's reaction. "Rarely saw you with that happy face, Reimu."
"S…shut up." Reimu weakly retorts. Then, a ringing sound suddenly catches their attentions, as she turns to the sound… "What is it?"
"Ah, someone's calling. Give me a moment." Kuro pulls out his phone and looks at the screen… "Oh, oops."
"Oops?"
"Just some friendly problems." Tapping on the screen, he puts the phone on his ear…
"WHY DIDN'T YOU CALL US WHEN YOU'RE ALREADY IN GENSOKYO!?" Someone screams from the other end, causing Kuro to pull out the phone temporarily to avoid permanent damage. Once the scream's over, Kuro decides to just turn on the volume so he won't have to put it on his ear. "You promised!"
"My apology. The creator herself dropped me in, and… something happened that I couldn't call you yet…"
"Excuses! You just wanted to…" Her voice then somewhat gets muffled.
"Sorry Kuro. Renko was so close in finding a right portal in getting into Gensokyo." A calmer voice continues the conversation.
"It's alright, Maribel. We know each other well enough." Kuro sighs. "Though, I have to ask if…"
"Don't worry, we will find our waAAH!"
"Maribel?" He looks at the screen to see it shows that the call's interrupted. "What happe…"
"Is that the phoney thing the Kappas are making?" Marisa looks at the new object with curious eyes.
"The kappas are making this? Why?" Kuro pockets the phone while asking.
"Won't you be worried of your friends? Sounds like they got into troubles." Alice is more concerned of the people from Outside World.
"I doubt it. Probably tripping into some…"
Just to troll him, a familiar gap appears right on top of his head, followed by two figures dropping straight on him. Of course he has already thought of them being dropped in her by Yukari, he didn't expect him being the landing zone though…
The girls from Gensokyo watch as the man being knocked flat to the floor by two outsider girls, one of them looks like a mini version of Yukari. The maiden isn't really scared of her father getting hurt that much, so she asks casually: "So… how often does this happen to you?"
"Too many times to count." That's the casual reply to her. Kuro then gently pushes the girls away from him. "Maribel, can't you use your power to defy gravity?"
"I'm so sorry. We thought that was you doing it, so…" Maribel apologizes.
"If I did, the portal wouldn't be filled with eyes." He rolls his eyes, then looks behind Marisa. "If this place is my place, I will shoot you right at your face Yukari."
"I expect that." The Youkai's voice causes the magician to nearly jump up in surprise. "Welcome to Gensokyo, young ladies." And with that the woman disappears as fast as she appears.
"…Well, I could accept that." Renko says, then glares at Kuro. "So, what's the reason that you couldn't call us sooner?"
"Before that, how about you introduce yourself to the natives here?" He slightly moves his head to the trio.
"…Ah, right. Sorry." Composing herself, the girl bows down and greets: "Hello everyone. My name is Renko Usami, nice to meet you all."
Maribel quickly follows: "Greetings. My name is Maribel Hearn. Sorry for dropping in without notices."
"Ah, it's fine. We know that woman too well." Reimu greets. "The name is Reimu Hakurei, a shrine maiden. That…" She points to her friends. "Is Marisa Kirisame and Alice Margatroid, magicians."
The former gives a thumb up, while the latter waves her hand to the girls. Renko then notices the pictures on the kotatsu, so she picks up and looks at it… and grins. "Hey, Kuro. Already going around and catching some girls for yourself?"
That earns her a paper fan swat to the head by a red-faced Shanghai… which makes the Alice and the original Shanghai to look at the doll in mild curiosity. Kuro sees the looks and says: "It's kinda like the mini Shion and Tewi, you know." The doll then lands on his shoulder and pouts while turning her head away from Renko.
"That… is amusing to look at." The puppeteer then looks back at her own doll. "I was trying to find a way to have my dolls gain conscious. Maybe one day I could ask you for that."
"You can ask anytime." His Shanghai then stops pouting and starts kicking her legs while moving her head left and right in a rhyme. "So, uh, what are you girls' plans today? I might head to Scarlet Devil Mansion to deal with the book immediately… And possibly avoid a hurricane in human village."
"The sky is pretty clear…" Marisa plans to say about the weather, before Kuro raises the newspaper up. "Ah, right, that."
"You keep stirring things up everywhere you go, huh?" Renko remarks, earning another swat from Kuro's Shanghai.
"We have talked with Patchouli about arriving to her library today. We will lead you there." Alice replies.
"Well ain't that convenient?" Kuro stands up and stretches. "Renko, Maribel, do you two have breakfast yet?" That earns him nods. "We should head there soon, so we could travel to somewhere else soon."
"Not doubting your abilities, but… how are they going to fly?" Reimu asks.
"We have learnt flying spells for ourselves, so we could travel easily." Renko proudly says.
"H…right." The maiden shrugs.
Everyone then stands up and walks to the porch, and the girls start flying up. After a second separating from the ground, they then hear flapping sounds from behind, so they turn their heads back to see Kuro now having three pairs of wings on his back… with the right being angel-like, while the left being demon-like. When he gets closer, he could clearly see shocking expressions on the Gensokyo girls' face. "I have many more stories to tell, just you wait."
"That… looks so out of place." Reimu feels weird looking at the left wings. While she's okay with the right… "Can you just fly without wings?"
"I can, but it feels unnatural."
"Hey, I forgot to ask." After shaking out of her shock, Marisa asks. "Do you guys know how to use Danmaku?"
"To my limited knowledge about the rules, we just have to use non-lethal spells, right?" Kuro asks, as everyone starts heading to SDM.
"Hm… to some extends, that's correct." Reimu nods. "But, you also have to do it in a beautiful way… yeah, your words might be easier to understand for the girls…"
"Like when these guys threw meteors at each other's face?" Renko reminds Kuro one of his fights on the Outside World.
"Or lightning spears. But that's live-or-die situation." Kuro scratches his head.
"… I believe you're referring to the indestructible mage we read in the newspaper?"
"The Lifemaker, yes. But that's one."
"Well, we do have some target practices here." Marisa then points a place from afar, where everyone could see wild fairies gathering around.
"That… is not an appropriate way to call them, miss." Maribel says disappointingly, earning nods from Kuro and Renko.
"Nonsense! Here, let me demonstrate to you all!" She then dashes towards the group and shouts: "WHO WANTS A PIECE OF ME!? COME HERE!"
"That crazy witch…" Alice shakes her head, followed by her doll. "At least she's good at showing things." Renko and Maribel immediately point to Kuro. "He's the same, huh?"
"Somewhat."
Reimu chuckles, then says: "While Marisa is busy doing her things, I should tell you more about the rules…"
Chapter 6 end!
Reference:
The Lifemaker is from Negima-verse.
Also, to make it simple from now on: The Outside World of this Gensokyo is Negima-Corpse Party verse (an AU/combined universe). There will be noticable changes that I will specify, otherwise it would follow the same origins.
About the spell rules, I have checked it, and with Kuro's self-explanations, that's how I understand it. If I'm wrong, correct me.
See you in the future! And stay healthy!
