How Long to Beat Beast of Reincarnation: Main Story, Full Clear and 100%

Short answer: a focused main-story run takes roughly 20–30 hours; a normal playthrough with side content lands around 30–40 hours; chasing 100% pushes into the 45–80 hour range depending on how much of the optional Nushi hunting and collectible sweep you take on.

Numbers compiled August 6, 2026, two days after launch, from our own playthrough progress cross-checked against early completion reports and aggregate tracking. Early-window figures skew toward fast players — expect averages to settle slightly higher over the coming weeks.

The three tiers

Run typeHoursWhat it includes
Main story only20–30Critical path, minimal exploration, normal difficulty
Story + sides30–40Side quests, optional Nushi fights, some collectibles
Completionist45–80All Nushi, full collectible sweep, both skill trees maxed, trophy clean-up

Game Freak’s own pre-launch guidance pointed at “approximately 30 to 40 hours” for a complete playthrough — our experience matches that for a player who does side content as it appears rather than beelining.

What actually eats the hours

Is it worth the completionist run?

If you enjoyed the core loop, the optional Nushi are the best fights in the game and most of the extra hours. If you only want the story resolution, a 30-hour standard run sees everything narratively — nothing plot-critical is locked behind 100%.

See our builds guide for how to spend those hours efficiently, and the Nushi boss list for what the optional hunts involve.
