Look up "Legend A dragon ball tale" on youtube, you should find it quickly enough

restrictions on flying for people who play Quidditch, he didn't like how many rules on flying it had, so he avoided it like the plague even though he is very good at flying. With swimming, on the other hand, you can't put the same restrictions as with flying since it's an entirely separate form of sport, so he prefers the new sport over the old one

either can work if you understand the context, since rest it would mean to turn it off and reset it would mean set it to zero, but reset it would work better for this context.

This guy definitely peeps into the womans bath house if he tried to make his friends comment sound less "dirty"

I realized a little late that I put "pray" and not "prey"

or "He wasn't making himself prey to them."

"he wasn't letting himself become pray to them." also works, and I feel like that's more of what it meant based on the original

It was stated in a prior chapter that Celebrimbor is a part of the system now and is unable to interact with the world of Harry Potter, so the most that Nick could do is make a golem in his likeness, but the elf himself can't be brought out of Nick's mindscape.

Then he's an a*s man-

From my perspective, I would assume that the Horcrux curse may be the safe way of splitting the soul, which is why it's the only one mentioned, but in every world with magic, there is always more than one way to achieve a goal, it's just that some are more dangerous to the user than others: such as forced fragmentation and destabilized fragmentation. Forced fragmentation would have a much higher chance of out right killing the caster, whereas the Horcrux curse uses the soul energy of another to control the damage of the soul split. As for Nick letting the wisp of Voldemort's soul escape being stupid, I can agree with that statement, but there is also the fact that prophecy's that have set factors need to play put or it just continues until it can be achieved. If Nick didn't let the soul wisp escape, then the world of Harry Potter might have either destabilized before Grindy's ritual, or it might have forced Voldemort to manifest in the soul fragment within Harry, allowing him to live on anyway. It's not my story, so I can't say for sure, but I can say that some things just happen in stories and sometimes the author can't think of any other way to make it happen after certain points.

No, think of it like this. Spells like the Horcrux are ment to preserve the soul, but if he broke it off on a whim, it would damage the soul piece and weaken it further than he had already. And this fanfic isn't the first place where potential "soul slips through space" happens since that's a thing in a lot of anime worlds, especially Isekai. it doesn't mean the security of the realm is weak, it just means that he took an opportunity to leave. And as I said in my previous comment, it's possible that Nick allowed it since the piece of the soul that broke off would have been extremely weak and fragmenting as soon as it broke of, meaning the piece wouldn't last longer than a couple of minutes to a half hour at most with how little would have survived, meaning it was basically like a human trying to grasp at straws while cut in half and without Deadpool's immortality.

He was about to be, but soul magic isn't so easy to contain, even more so since it was the main part of Voldemort's soul that was in the realm. I would like to think that in order to try and save himself, he split his soul once more in order to try and send the last sentient fragment he could to his last living Horcrux, which was Harry since the other girl was killed by Grindelwald's subordinate. Due to the soul fragment being so weak, it could have slipped out when Nick left and he just didn't care to pay attention to it since it wouldn't be able to reform due to basically being a wisp with how little of Voldemort's soul was even in the body before it entered the realm in the first place.
