The anime of Tower of God ends around a specific chapter in the manga, but it varies depending on how the adaptation was done. You'd have to check specific manga chapters to be sure.
The Tower of God anime's ending in the manga is kind of tricky to define precisely. It's affected by factors like the focus of the adaptation and the need to fit the story into the anime's runtime. But generally, you can find hints and clues by comparing key plot points and character developments.
It's a bit tricky to pinpoint exactly. The anime adaptation of Tower of God doesn't have a one-to-one correspondence with a specific manga chapter. It sort of covers a certain arc but doesn't end precisely at a defined manga point.
It depends on how closely you want to follow. If you want to avoid any repetition, start from the chapter that comes after the final scene of the anime. But if you don't mind a bit of overlap, you could start a few chapters earlier to get a smoother transition.
