Oh great, it got purged. And the official source is way behind the fan scanlations. Mangaup seems to be a hybrid subscription / coin system, with older chapters being available for $5 a month (at least it was in 2024) and newer chapters requiring consumable coins, which you get 800 of free for signing up.
Seems better than Kmanga's all coins all the time system (unless they've changed that) but it's still less generous than Shueisha's various sites, and Vizmanga.
Feels like official paid manga's very fractured right now, but honestly, it's better to have competition than collusion. Look at how bad Crunchyroll's gotten now that it's been bought out by Sony, merged with Funimation, and only has HiDive and Netflix to compete with.
