Yu Yu Hakusho：Slugfest

This idle battler offers short, easily interruptible sessions suitable for one-handed play, making it a good fit for quick breaks. While the core gameplay is mindless and replayable, progression is heavily gated by a pay-to-win monetization system that creates significant walls for free-to-play users. It's best suited for players who enjoy collecting characters and don't mind the aggressive monetization, or those looking for a game to passively progress in the background.
