Sword Art Online

Sword Art Online is the isekai and virtual reality anime that sparked a global phenomenon and introduced millions of viewers to the concept of being trapped inside a game. When 10,000 players log into the groundbreaking full-dive VR MMORPG Sword Art Online, they discover they cannot log out — and that death in the game means death in real life. Kirito, a skilled solo player, must use every ounce of his ability to survive, find allies, and ultimately clear all 100 floors of Aincrad. A-1 Pictures brings the floating castle setting to life with gorgeous visual design, and the stakes of every boss battle carry real emotional weight. The Aincrad arc remains a compelling piece of virtual world storytelling, and the franchise has continued expanding with Alicization — widely regarded as the series' most ambitious and technically impressive arc to date.
