Sword Art Online Review: Trapped in a Game, Fighting for Survival

1. Introduction

Sword Art Online (SAO) burst onto the anime scene with a revolutionary concept: what if dying in a video game meant dying in real life? Created by Reki Kawahara, SAO blends action, romance, sci-fi, and psychological themes to deliver a high-stakes adventure inside immersive virtual worlds.
