Yutaka looks at the time. Memorises it.
Kyūbey?
"Who are you? Where are you from? Why are you here? Why do you make magical people? I'm certain you have multiple agents or bodies or something and it would not be hard for me to hunt each and every one of them down one by one until I exterminate your species from this planet."
"I have infinite time. Literally. I don't think you understand how thoroughly outclassed you are. You could answer me now and save both of us some time, or I could dictionary crack you. Your choice.
"What does that mean. How does making magical people let you harvest magical power."
Humans are unique in the universe for having emotions in healthy members of the species. These feelings are convertable into generic energy, somewhat like the way human civilization uses electricity. Taking control of the process of making wishes and the conversion into witchhood afterwards and collecting the full grief seeds allows galactic society to run and may stave off the heat death of the universe. But I am not afraid that you will destroy this body. I don't feel anything about it at all. You can if you want to, and it doesn't matter and will not affect me very much.
"—this isn't the behaviour of a species humanity can be at peace with, you know. This is the kind of thing that would mean war. Maybe you don't care, maybe you think you could take us, maybe you're right. But by choosing to do this you have marked humanity as your enemy."
Magical shortcuts are what has brought humanity to where it is now. Human beings were using stone tools for millions of years before inventing cooking, do you imagine it took no magic to make the leap? We have been with you at every stage of development. We have been behind every stage of development. It is really a beneficial trade if you think about it.
"Oh that's pure bullshit you sanctimonious self-important asshole. The account of the development of human technology does not have discontinuities like that other than the invention of agriculture and the industrial revolution and, sure, if you wanna say some magical person came up with those, fine, whatever, we would've gotten that eventually. The timeline of human progress does not match a series of discrete individual heroes. But whatever, do you have any parting shots before I erase your memories?"
Rewinding fractions of a second to just skip back to right before he pauses time is also exceedingly cheap, so he redoes that conversation in stopped time a few times to see which parts of it are path-dependent. He never said he wasn't going to dictionary crack Kyūbey if it cooperated, after all. But it does seem like it was telling the truth, or at least that it's very consistent with which lies it tells. Can never discount that possibility. He is never taking anything this creepy little creature says at face value ever again.
...he's not having much of one. It seems like now that it's no longer fresh and he's already vented his anger on the weird alien he's just feeling numb. Although, well, who knows, he's the king of denial and emotional suppression, it might come hitting him later.
Actually, scratch that, it's absolutely going to hit him later when he finally sees Haru again. He will not look at Haru in his bed, he doesn't want to break down crying.
So. He transforms again, roof hops to Haru's place, and drops Haru's notes to self on Haru's desk.
And alongside those he adds a note, in English:
I don't actually know the contents of these notes, but it is VERY IMPORTANT that no matter what they say you DON'T USE TELEPATHY.
DO NOT TRY TO USE TELEPATHY NO MATTER WHAT, IF POSSIBLE DON'T EVEN THINK ABOUT IT
I can provide other evidence of magic than that. Text my number whenever you want, but absolutely under no circumstances use telepathy.
He adds his number to the bottom of the note, and then goes to sit on the roof.
I don't actually know what your notes have covered so far but
it turns out witches are actually magical people who fell into despair and/or ran out of magic
if either happens the other does too
and it knew and the process through which this happens generates energy that they harvest
it's the whole point of the endeavour
Haru's notebook situation is kind of a monstrosity, a great big nested-index pile of stuff all collected in a three-ring binder and full of extra paper stapled or paperclipped in. He pages through it. He skips around a fair bit. Eventually: "Yutaka? Do you want breakfast?"
"I'm s-sorry. Just f-five more m-minutes." That won't be enough for him to calm all the way down but sue him he's selfish. He knows the Haru that loves him would want him to be selfish this way.
He just kind of wishes the Haru that loves him had frontloaded the love in the notebooks somehow. It feels a lot more like an imposition like this.
"Your mental health was already obviously the limiting factor and that does not get any less true if your mental health collapsing could turn you into a witch. Is... the process where you get me to fall in love with you and then I am for the rest of the loop... still a good plan, if we are doing this... many times."
"Yes," he says, vehemently. "I—you're my reason. To keep going. I'm sorry. I'm so sorry, I know that's—a lot—but it's you. It'll always be you. I'm not a good person, I'm not that good, I'm not good enough to, to, to do this, to keep doing this, for—for as long as it'll take—not just for Tokyo. I'm just not. I can't, I don't, I don't have the strength. I'm sorry. I wish it was you here and not me. You'd do this better. But I'm the one stuck here, and I—need—I need you."
"I - I'm not sure you understood the question, that's not what I meant. I'm not going anywhere, except in, uh, all the senses that's not true. But I could imagine finding the Fifty First Dates thing - I haven't even seen that movie, but - I could imagine finding it more painful than sustaining, having to do it over and over? And I can be here to help you and give you advice and try to come up with ideas and stuff without fifty first dates, it that would be better. But maybe it wouldn't, maybe that would suck, I don't know."
"I don't—I don't need your help—or, I do, I do need and want your help with—ideas—but I need you. I need to—be yours—and I need you to be mine. I'm sorry. I am—banking a little on the fact that you like to be the most important thing in someone's life, I'd be a lot more reluctant to say this—but I need you to love me. I need you to love me and only me. I need to be your one and only, and I need your love. Just yours, and no one else's, never anyone else's."
"I am not flinching about the - how shall I put it - the intensity, here, that's fine, it's sweet, my question was a different thing, but, sounds like that's - my answer, I guess." He squeezes Yutaka's hand. "And there's, uh, proof of concept. If what you want to do, what you need, is - this over and over."
"...although it just occurred to me that—I don't know if you'd like this, given—but—since we know this loop won't be the last you could—wish your memories back.
"I selfishly don't want you to become a magical boy and have Kyūbey's attention and the risk of potentially witching if you get too sad but—separately selfishly I want you to love me. I already said that."
"Which, not that I love letting Kyubey control the rate of this happening but it's a rate that doesn't most of the time lead to human extinction, probably, though I don't know what the plan for Walpurgisnacht was. - does this thing have a gender, my notes have 'he' but you've been saying 'it' -"
"...I used to say 'he' because it—sounds like a boy, when it speaks into our heads, and uses the boy personal pronoun—but—it's an alien. It's some kind of evil alien farming humans for electricity. It explicitly made its body look cute so we'd trust it more. If it has a gender it does not have a human gender."
"So I'd basically be doing this solely for the memories - or, in the long term, the notes I can get out of having a better angle on the memories - and the dyspraxia cure, both of which are pretty good, plus bonus information that probably doesn't matter about whether my costume looks the same." Write write.
"...magic exists. And—Kyūbey said they took control of the wish mechanism—I should've asked more about that, I don't know, but—it's too early to decide that we can't have our cake and eat it too. I don't want to say it's impossible for you to keep your memories, I don't want to—just give up."
"...that makes sense. Uh, as long as you are... keeping yourself clear of obstacles that could turn you into a witch if it ever becomes clear that the cake won't work that way. I don't... think it is likely to be recoverable, if you do that, and I think I still wouldn't think it likely if you died and turned out to reset then too."
"Well, I guess I could make you take me on fancy sushi dates till I can get all my mental ducks in a row to say it back but apparently I could also just take a magical shortcut. ...will Kyubey leave on its own after I wish if we want privacy or will I have to awkwardly show it the door."
"If I can't like. Do stuff. Without going into spirals that could make it happen again. How long do I have to write things down before it's too expensive for you to undo this. I like - I think that if we were taking this loop off and the only things I had to do were emotional processing and hiding in your lap all the time I'd cope but I cannot imagine trying to fucking. Do grocery shopping. Let alone show up to school even with all my assignments already done. Someone would say something very slightly wrong and I'd start having a panic attack and - and maybe I'll be better in fifteen minutes and maybe I'd be better tomorrow and the longer I wait the less reversible it is, so how soon do I need to be sure."
After a minute Haru figures out a configuration where he can mush most of his face into Yutaka simultaneously with writing - it involves sitting on his lap facing him with his arm going under Yutaka's arm and his eyes just barely peeking over his shoulder - and he writes things, shivering occasionally, pausing sometimes when he needs that arm for hugs more than he needs it for writing.
"I love you and I hope I am okay in fifteen minutes because it is going to be so annoying if I have to stop doing that for a little while lest I freak out and turn into a despair monster in the middle of history class!" says Haru. "Ugh. I could probably get Ren to say I fell down the stairs?"
"You really really really really have to not witch, which is why I am not describing it to you," Haru tells him at the end of this time, setting his pen down. "But if there is anything that not knowing is freaking you out more than any possible answer I guess you can ask. - also if it were in any doubt I forgive you for the phone sex loop thing."
Oh God he had completely failed to even think about that, and good thing too because he did not need to add any more anxiety to the past twenty minutes. "I love you. Thank you. I—just want you to be okay. I'm curious about what witching felt like but not in a—freak out way.
"What do you want to do, my radiant sun?"
"I am presently very ambivalent about a whole lot of things. But I think the one I'm picking is the one where you take this back for me," he pulls out the most recent notes. "And then I can be useful for anything this loop. I can try this again when it's not quite so recent. Maybe only once we're actually in Australia or Paris or whatever and explicitly not trying to accomplish things and all I need to do is be clingy and demanding and this will somehow constitute a decent vacation for you because you're kind of nuts. I love you."
