Sword Art Online: Progressive Volume 4 (Manga)

While Nezha attempts to atone for his misdeeds by completing a quest to learn the Martial Arts skill, Asuna toils alongside him for her own reasons - and learns a troubling truth in the process.  Meanwhile, Kirito's uneasy alliance with the other front-runners seems to be holding, but are they really ready to face Sword Art Online's second-floor boss?  And if the Legend Braves are neither legendary nor brave, can Nezha still rise to the occasion and seize a hero's prize?
