You know what, I'd like to try and at least get the Yukihiro Island story done and done right. Let's see if we can start with a rework of what I'd done of it so far. Introducing the Negiplane earlier in this continuity makes sense with Ayaka already in the team.
The Obligatory Beach Episode.
"Negi," Chisame's voice cut through the night like a well handled, precise and exact knife, "just come... I mean, go sleep already."
"Just a second, Chisame," the boy said as he kept working on his laptop.
"I know," Chisame said, "I'm the last person who should ever complain on others spending too long in the Internet, but-"
"Maginet," Negi said.
"Excuse me?" the girl asked from the bedroom's upper bunk.
"Maginet," Negi replied, his eyes still on the screen. "The special global computer network for magic users."
"I didn't know that," she said. "Why didn't you ever tell me about it?"
"I knew you wouldn't be interested," Negi shrugged, still without looking at her.
Chisame propelled herself up on her elbows on the mattress. "You know I'm interested on all things computer!"
"But you also try to avoid most magical things," Negi answered, his fingers softly tip-toing on the keys. "Honestly, Chisame, why are you so upset now?"
"Why am I so upset? Little freak, you've been running yourself to an early grave lately! You barely sleep, you split your days between training and teaching, and as your guardian here, that's my responsibility! My fault! So stop doing this to yourself and try acting like a normal boy for once!"
Now he did look at her. "Of course I'm not a normal boy. That's the whole point of what I've been doing all these years. That's what I've struggled for so much. My father wasn't a normal man, so I see no reason why I should try to-"
"Your father, your father, it's always your father!" Chisame snapped. "Why don't you start thinking for yourself instead of thinking based on what your father did or would have done?!"
"Why are you so angry at me?!" he snapped as well, being as he was antsier than usual ever since the incident with the dragon. "Am I being too loud with the typing? I can take it to the living room or even-"
"Forget the damn typing!" Chisame told him. "I'm fed up because you're a moron, that's why! Because even after everything you saw in Kyoto, and everything the other you told you, you still are intending to go ahead with this by yourself, when it's clear you have absolutely no chance in hell going that way!"
"Ah?"
"That's why you didn't tell me about that Maginet, right?!" Chisame accused. "So you shouldn't have to share this research with me! Despite knowing I'm far better qualified than you for Web searches!"
"Not to offend, but I doubt that applies to magical Web searches!"
"We won't know until I've tried it, right? But you don't want me to, because you're still deadset on doing things all alone!"
"I'm not saying I don't want your help, but you must think of what's best for yourselves, too!" he argued.
"What do you know about what's best for us?" Chisame challenged him. "You don't know what's the best for yourself! If you had any sense, you'd drop this insane quest before it kills you, and settle down for a quiet life like a normal person! I'm sure that's what your father would have wanted for you, if he was a good person!"
"What do you mean with if?!" Negi found himself actually raising his voice back at that.
"Well, let's be honest, if he's actually out there, and he was available to save you five years ago, why wasn't he ever around to at least tell you and your cousin he was alright and you shouldn't worry!"
"He was there alive and well right before my eyes!" Negi argued. "He didn't need to tell me!"
"Yeah, and what about the rest of the time?! What kind of father only shows up when his children are in deadly danger? That's not what parenthood is about! Parenthood is a day-to-day struggle, a constant protection, love given every day, not only when otherwise your children are going to be killed by a demon horde!"
Negi's eyes watered at an alarming rate. "You... You only say that because you had a bad father!" he accused, too caught in the heat of the moment to mind much what he was saying.
"We aren't talking about my father here! And I'm not like him! I accept my responsibilities, while you want to be like yours and just run away to do your thing! Leaving those who care about you in the dust!" her eyes were watering as well, as her voice sizzled angrily. "You may like talking big about how responsible you are, but in truth, you're being the complete opposite! You can't be responsible when you gamble with your own life! Snap out of those lone hero fantasies or you'll end up just like him! Lost and abandoning those who counted on you!"
That hit Negi harder than any of Sextum's blows.
He shuddered, standing up and backing away on shaky legs, and then ran out of the room, crying his head off. "I... I can't believe you said that!"
Chisame stood there, not making any attempt to follow him, just planting a hand over her face and crying bitterly on it.
Satomi lifted her head from the pillow in the lower bunk and muttered, "That didn't go as expected, did it?"
"Why didn't you say anything, then?!" Chisame growled.
"I don't have a good father either, so I wouldn't have known what to say," the scientist absently mused. Chamo kept on snoring in his panty drawer, turning around and scratching himself in the furry belly. "Don't you think you perhaps were too harsh on him?"
"Shut up!" Chisame said, wiping her eyes stubbornly. "What about all the pain that brat causes u— those who care about him! Telling us we're interfering! After all we've done for him! Who does he think he is?"
"I don't think he actually said that..." Satomi smacked her lips together.
"Who cares! He was thinking it!" Chisame screeched.
Satomi reached up to loosely hug her pillow. "Well, you'd know that better than me. But you also know he'll be upset over this over the next days to come, don't you?"
"Please, he's too spineless to hold grudges with anyone," Chisame rolled back on the bed, facing the wall. "By tomorrow he'll be back to trying to get on my good graces, you just wait..."
It occurred to Satomi then perhaps she actually had overestimated Chisame's knowledge of Negi's psychology a fair bit.
Three days of oddly uneventful peace later:
"- I can't believe he won't talk to me yet," an oddly rattled Chisame murmured over lunch at the cafeteria. "I mean, wouldn't it have to be the other way around? That I'd be the one pissed off at him and giving him the cold shoulder? I'm the Tsundere, for Pete's sake!"
"Well, he wasn't the one to insult your father, though..." Asuna pointed out.
"He did, too!" Chisame said. "It's just I don't care because he deserves it, but still!"
"So..." Konoka said in a low voice, sitting between Asuna and Setsuna, opposite Satomi, Hasegawa and Tsunetsuki, "isn't he sleeping with...?"
Satomi raised a hand.
Konoka whistled. "It's serious, then...!"
Chisame began banging a fist on the table, scaring those around them. "Like hell I care, though! If he wants to play hardball, that's his problem! I'm not going to apologize, ever! I meant every word, and I still do!"
Konoka helpfully handed her a handkerchief over the table.
"Thank you," Chisame said. "Um, this reminds me, I've gotta go use the toilet. Because, hm, I had prune juice for breakfast. 'Scuse me," she then quickly headed for the restroom.
Without missing a beat, Hakase held Matoi by a sleeve. "No, Sempai, you're staying here..."
"Drat!"
Asuna's Asuna-sense gave her a full body shudder then, and a moment later, a few white petals drafting through the air heralded the radiant arrival of Ayaka, smiling in a beautiful, blissed out way. "Oh, there you are, Asuna-san, Konoka-san, everyone! I hope you are all prepared for the trip!"
"Which trip, Iinchou?" Asuna asked.
"Why, the trip to my private island for the next weekend, of course!" Ayaka replied, taking the seat previously taken by Chisame without even asking, and sighing very happily. "I've just talked it with Negi-sensei, and he was extremely contented to come along with me, I mean, us!" Her face and tone suddenly soured. "At least until I reminded him Chisame-san would have to come as well. What has she done this time?"
"Um, Iinchou?" Asuna lowered her voice. "Wasn't that trip thing just some excuse to cover up-"
"I know, but by now too many people has learned about it, and I can't back away on it without losing face!" Ayaka hissed/whispered, far from her usual elegant and dignified custom. "Don't try to dodge my question! What did Chisame-san do?!"
"She and Negi-sensei had a fight, that's all," Setsuna told her. "I wouldn't worry that much, they're bound to-"
"What?!" Ayaka cried. "What sort of fiendish act could move an angelic martyr like Sensei to become that angry at someone?!"
Matoi began toying with a knife as her eyebrows quivered quite erratically. Ayaka didn't even notice it.
"She badmouthed his dad, sort of, but to be honest, the stubborn brat was asking for-" Asuna began.
"Whaaaaat?!" Ayaka further cried, and by now those in the neighboring tables were listening intently, making Setsuna extremely uncomfortable. "The nerve of that bullying woman! Speaking against an apostle of true justice like Sensei's honorable father! What is her problem, anyway?"
By now, Hakase had to actually hold Matoi from behind, as strongly as she could, to keep the fuming and hissing Sempai at bay. Ayaka somehow missed out on that as well.
Konoka gestured at her to calm her down. "Iinchou, please, calm down, will you? Chisame-san must be about to return from the restroom, and-"
"Oh, so that's where she is!" Ayaka rose back to her feet, then began stomping for the bathroom. "Hiding from me, isn't that right? Well, I'll teach her to mind her big mouth!"
Asuna and Setsuna would normally have tried to stop her, but right then they were too busy helping Hakase to keep the madly wheezing and growling Matoi pinned to the floor so Ayaka could keep on living still oblivious to the threat to her life the Sempai currently posed.
"CHISAME-SAN!" Ayaka said as she stormed into the bathroom. "I demand an explanation as for why you and Sensei are-!"
Then she came to a sudden halt as she saw Chisame exiting a stall, with a soaked handkerchief in a hand, extremely reddened eyes, and slightly askew glasses.
A terribly uncomfortable silence from both parties ensued.
"Um," Ayaka finally said, with a knot in her throat, "I just, I only came to ask if you still were willing to come to the scheduled retreat..." Then she raised a finger, "Negi-sensei said he wouldn't come unless you did!"
"Oh, really," Chisame said in a terrifyingly dry and bitter voice.
Ayaka nodded very quickly. "Hm, of course, he won't admit it to you yet, but I'm sure, sooner or later he'll come around to- It's been difficult for you as well, hasn't it?"
"I don't know what are you talking about."
"Oh, naturally. My apologies. Regardless, I, I would like to have you there as well, and-"
"Why?"
Ayaka sighed and just said the truth. "Because, I don't have the heart to apply discipline on Negi-sensei. But you do. Right now, I don't know if that means my heart is too soft or yours is too hard, but... It started because he kept insisting on placing himself in danger, right?"
Chisame replied with a non-committal grunt.
"Right," Ayaka answered herself, "and then he began making an example of his father, and you thought you had to stop it, so of course, he..."
"If you could deduce all of that, Sherlock," Chisame growled, "why did you come here howling for my blood?"
"... I hadn't stopped to think about it," Ayaka sheepishly replied.
"Yeah, well, that's always the problem with you."
"No, the problem... sole problem, I might add... with me is I love Negi-sensei too much as to be stern to him, but I can realize, as soon as I stop to think about it, the need for someone to put their foot down and set limits for him, even if he doesn't like them. That's why I'm willing to admit Negi needs a strong older sister like you, Chisame-san."
"Gee, your approval fills me with joy," Chisame said.
"Think whatever you want of me, and I'll do the same for you," Ayaka shot back. "But, no matter how you put it, living under the same roof as someone who is always upset at you is an annoyance, wouldn't you agree? Why not, then, to come along and work out a rational solution for this in a relaxed environment away from the stressful day to day duties? You know, like civilized human beings?"
"..." Chisame said.
"How many other chances to visit an island in the South Pacific will you ever get?"
Chisame made a few gestures of angrily reach over to Ayaka with clawing fingers, but finally just collapsed unto herself with a sigh. "Whatever," she said.
Ayaka smiled and nodded. "Now that's the Chisame-san we know and lovingly tolerate!"
"You realize, of course," Yue's voice said from within a nearby toilet stall, "that conversation would have raised many questions if someone else had been here to listen to it, don't you? Also, could one of you pass me some more paper? I just ran out of it here..."
Three more days of oddly, and by now frankly worrying, uneventful peace later:
"This is it!" Ayaka proudly exclaimed, spreading her arms open, as she led the Ala Alba into the suitably splendid Yukihiro Private Airport, under a colorful parasol held by the always close, dutifully stonefaced Roberta. "The pride of the Yukihiro Aerial Fleet! The vessel that will take us to oceanic paradise on the wings of our love, I mean, our comraderie, our—!"
Negi began emitting a series of short, strangled sounds as his face lightly twitched, the scar on his cheek subtly puffing in and out.
The brand new, shiny airplane had his smiling, winking, somewhat idealized and even more pretty boy-ified image painted on both sides, making a 'V' sign with a hand and surrounded by floating pastel colored hearts.
"Ooooohhhhh!" Makie cooed, as her cheeks flushed brightly pink. "That's so gorgeous, Iinchou! You've surpassed yourself this time!"
"Oh ho ho ho ho, thank you, Makie-san!" the blonde laughed. "I made sure our team decorated the Negiplane to the best of our capacities! Emblazoned with the bold yet loving figure of our fearless leader, we shall spread our mission across the oceans!"
"Negiplane?!" Chisame yelled. "Who do you think he is, Batman?!"
Negi grumbled, making sure to look away from her. "Of course not, unlike me, he doesn't abandon those closest to him, does he? Because he's a real hero unlike my Father, isn't that right?"
"Oh, cut it out already, you!" Chisame growled at him.
"I'm not sure it'll be safe traveling in this thing," Yuuna opined. "Won't we be shot down in sight as soon as we fly over another country's sea territory, or whatever it's called?"
"If I were a president and I saw a clown plane flying over my territorial waters, I'd have it shot down, too," Skuld agreed soberly. "It'd be sure to transport crazed supervillains."
"Negi-kun was a super villain," Makie pointed out.
"That's different, he—" Ayaka began.
"And Paru-chan wants to take over the world."
"She does, yeah, but—"
"And technically, you often hire Deadpool-san, who IS a supervillain of sorts, so doesn't that also kinda make you a—"
"I think I got it already, Makie!"
Misora snickered. "Why don't we repaint it into a Chiuplane instead?"
Chisame growled.
Akira blinked. "Huh? What does that Chiu person have to do with any—"
"She's just talking for the sake of it!" Chisame interrupted, waving a hand around.
"A Chiuplane..." Matoi hissed, chewing on her lower lip and moving her hips in slight circles, ever so slowly. "I really like the sound of that, yes, I do..."
"Do you have a pilot for this flight already?" Saber asked, vaguely interested. "If not, I would like to volunteer myself for the task. Since I apparently have to go at all, I might as well make myself useful..."
Shirou blinked. "Do you really can fly one of these? But how, they didn't even exist during your-"
His Servant half-smiled confidently, closing her eyes. "That'd be no problem for me. My A-ranked Riding skill allows me to handle any sort of vehicle as easily as I'd manage the saddle and reins of a steed. There is no great science to it, actually."
Makie, Sakurako, Ai, Sora and Rito tilted their eyes upwards in silence, and a shared thought balloon showing Saber literally stradling the top of the Negiplane and madly riding it all over the ocean appeared above them. Then they shuddered collectively.
Ayaka smiled benevolently at the Heroic Spirit. "Sure thing, why not? I had planned to recruit Leigharch-san now he's gotten his pilot license, but I suppose King Arthur is enough of a good replacement for the Yukihi-"
"SABER-SAN WILL DO JUST GREAT, THANKS!" almost everyone eagerly interrupted her, visibly disturbed all of a sudden.
Saber took pause at that. "This Leigharch person, who would he happen to be..."
"Let's just say I would actually love to go in that plane with him, but only if it were the two of us in it," Itoshiki bitterly stated.
"Wow, that sounded really, really gay, you know?" Chamo asked him.
"I'm just saying that he'd crash us into the ocean at peak speed before half an hour, that's all!"
"So you're basically saying you want to die with him? That's even gayer, sheesh...!" the ermine pointed out.
"It sure does sound that way, doesn't it?" the man realized. "I'M IN DESPAIR! Being so easily taken for decadent bishounen forbidden love bait has left me in despair!"
Haruna sniffed in disdain. "Well, if you've got a talent for something, why shouldn't you be proud of it...?"
I guess she couldn't stick around with Shirou for whatever reason?
