Hunter x Hunter: Heaven's Arena

Heaven's Arena is a masterclass in introducing a complex power system. Gon and Killua climb a 200-story tower, facing increasingly difficult opponents. Unlike standard brawlers, this arc focuses on the tactical application of Nen, turning every fight into a high-stakes puzzle. It is essential for fans who appreciate intelligence over brute force.

The pacing is deliberate, ensuring every victory feels earned. It serves as the perfect bridge between the early adventure phase and the darker, more mature arcs that follow in the series.
