Wait actually hold on, I can do this math better

We know that GoD inherited about 85% of the original Reaper skills while he was studying under him. His motion perception, ability to absorb information, desire for improvement were twice that of the original. We can assume this means twice the learning speed. Within another 10 years, he could've surpassed his predecessor.

So for the 2nd Reaper, 10 years = 15%
As this was when he was learning on his own, similar to Korosensei, we can assume that for Korosensei himself, 20 years = 15%, due to his student having twice his learning capacity
(at least, considering the implication that he had more failures than his student even had successes)

This would imply that Korosensei reached his full level of ability over the course of 133 years.

Unknown time spent as a child, likely no more than say.... 12 years, before he began his killings

Unknown time spent training the Reaper, but considering the numbers above we can assume it was likely no more than about 66 years at the absolute most, likely less considering his teaching skills combined with his students’ talent.

Meaning that the possible interpretations of Korosensei’s age range from

66 years,
78 years,
133 years,
200 years

Or possibly more

And considering his superhuman medical genius and ability to keep himself in peak condition, it's not out of the question to assume that, similar to Batman, he has slowed his aging process.

This also means we can assume the 2nd Reaper, at the time of his appearance is, at the very least, 56 years old.

Which would imply that Korosensei was already well-established as the deadliest human who ever lived anywhere from 22 to 10 years old

Man is a ******* freak

Jesus ******* christ. 200? Possibly more? The man looks like he’s in his 20s at best.

Yusei Matsui once said in an interview that he never really thought about the names, ages, and other details of the two Reapers as he believed they added nothing to the plot, so this is definitely not something aimed at, but man, is it plausible. A sound logic based on what we have (what even sparked this line of reasoning in the first place?) with no real counterpoint (or none that I can think of right away).

I can take that aging thing a step further,

Remember how I casually came up with a crazy notion about how Gakuho conducts studies on immortality since he has a "top secret" hour in his schedule and is said to be interested in eternal life? Koro may have tried just that and happened to be successful with it. Absurd it may be, but it's fun as hell if you're willing to entertain it.

I always thought that Koro was a freak, but this interpretation makes freak an understatement. And what baffles me is the fact that he is not even the one with the most potential to do all this—an assassin; he doesn't really aim higher either; he just happens to be the one while doing whatever he feels like doing.

I'm not sure what implied that Koro was already well-established as the deadliest human who ever lived between the ages of 22 and 10 years old, though.

Yeah him not thinking about the ages is uh... apparent.
Them not having names makes sense though. Koro's parents probably never named him and Reaper 2 probably completely threw away his former name and never gave a shit. Being nameless is also probably pretty useful for an assassin.

Idk just hearing that there were actual numbers for the Reaper's teaching timeframe got me pondering.

And also yeah. What're the odds of the two objectively most talented people in history, mathematically proven to be so, meeting each other and both deciding to kill people?

As for what implied his lethality, it was the fact that he was assumedly already well-established as the Reaper when he met his student, and in the flashbacks to that day he looks like he's in his teens at most(then again he ages slowly I guess) so I assumed 12 was a safe bet, since he likely started killing around 8 or so going off of that usually being the oldest you'd still call someone a child, add that to the 56 years he's implied to have trained his student and you get the 66 or so years he's likely be during the betrayal (at least).

Although, considering the 133 years he would need to master all his skills...

And assuming he learned while teaching his protege, which is likely...

And with it being a safe assumption that they likely both began killing at say, age 10...

I would wager that by the time of the series itself, Korosensei is 143 and his student is 66.

Some ******* how. Peak human skincare

Honestly it kinda annoys me that Karasuma and Craig are stronger than the Reaper. It honestly doesn't make sense.

Name-wise, it’s fair; I can see multiple perspectives where both the story and the characters benefit from it. Having said that, he could've added a single box or even a line in the databook or something that at the very least gave them a nationality, age, or some other characteristic to make them a bit "down to earth" (not sure if that's the right word for it)

Considering Reaper’s skill boner, he would’ve been drawn into being an assassin somehow either way, I guess, so the latter is pretty likely, I’d say.

And that skincare skills is also justified with that whole "assassination requires omni-capability" shtick, kek.

You mean in pure strength? If so, I don’t think he was any weaker than Karasuma. There are mainly two reasons:

1: Remember how Karasuma called him out of practice? After betraying Koro (his only sparring partner), Reaper most likely never engaged in proper H2H combat.

2: Reaper wants to acquire as many skills as he can, but he doesn't seem like the kind to conquer those skills. That's somewhat shown by how frequently he tries to come up with new skills instead of mastering the ones he was taught, and later, instead of actually pulling off the scythe, he just mimics it with a gun.

What I mean by all that is that he, an already half-assed combatant (which, of course, was still enough to keep him in the top three), deteriorated even more over time. However, given that he could still match Karasuma in strength, it's safe to say that while he was learning from Koro, he was stronger than Karasuma.

Craig, though, makes sense to me: Man is a ******* war god, a war fetishist who spends his free time taking down armies. Reaper has no reason to be at his level; he himself says that close combat is a skill that is unnecessary 99 percent of the time. If you consider his personality too, he was probably never good enough at it to be on Crag's level.

Craig being stronger than Reaper does not annoy me; how he was handled does, tho.

1: Ah yeah, true. Forgot about that. Probably was more of a match for him during his proper apprenticeship.

2: That is also a pretty good point.

3: I guess it's just odd that Karasuma and the Reaper are pretty solidly the two biggest badasses the world has to offer, and suddenly there's some dude Karasuma has never heard of who's three times his better. I guess him existed and being that strong isn't as weird to me, it's more the fact that he seems like he'd be more well-known. It almost feels like an asspull to have an opponent Karasuma can't just pummel into the dirt.

Technically, he was well-known. It's just that because AC focuses on two main professions, teaching and assassination, we never got much information on other professions, such as soldiers, in Craig's case.

And that's really all I can say. Like you, I don't really like how he was handled either, but eh, I can overlook it; he took like 5 chapters at best, and he passes the cool enough test.

Btw, since you're already here, there was this matchup I was thinking about for a while, you think a matchup between Human Koro and Tentacle Reaper would work? Either I'm overlooking something simple or this seems like a stupid yet entertaining matchup.

"Omnipotent Assassin vs. Perfected Super-Destructive Life-Form" you know.

That's actually not a bad idea

I've often interpreted his lessons to the kids following their failed assassinations as "here's what I would've done"

And I've often thought that without Korosensei having prior knowledge (somehow) his Reaper self could probably do it

Aha. Gotta make a thread on it to see how it goes then. Just need to wrap up that last revision first tho. Ugh.

Welp, I'll be relatively free for some time, might as well try my luck a bit tomorrow.

Don't you dare go on a long hiatus in the meantime. Can't argue for both sides on vs threads smh.
