Centuries ago, mankind was slaughtered to near extinction by monstrous humanoid creatures called Titans, forcing humans to hide in fear behind enormous concentric walls. What makes these giants truly terrifying is that their taste for human flesh is not born out of hunger but what appears to be out of pleasure. To ensure their survival, the remnants of humanity began living within defensive barriers, resulting in one hundred years without a single titan encounter. However, that fragile calm is soon shattered when a colossal Titan manages to breach the supposedly impregnable outer wall, reigniting the fight for survival against the man-eating abominations. After witnessing a horrific personal loss at the hands of the invading creatures, Eren Yeager dedicates his life to their eradication by enlisting into the Survey Corps, an elite military unit that combats the merciless humanoids outside the protection of the walls. Eren, his adopted sister Mikasa Ackerman, and his childhood friend Armin Arlert join the brutal war against the Titans and race to discover a way of defeating them before the last walls are breached.

Ever since the release of the innovative NerveGear, gamers from all around the globe have been given the opportunity to experience a completely immersive virtual reality. Sword Art Online (SAO), one of the most recent games on the console, offers a gateway into the wondrous world of Aincrad, a vivid, medieval landscape where users can do anything within the limits of imagination. With the release of this worldwide sensation, gaming has never felt more lifelike. However, the idyllic fantasy rapidly becomes a brutal nightmare when SAO's creator traps thousands of players inside the game. The log-out function has been removed, with the only method of escape involving beating all of Aincrad's one hundred increasingly difficult levels. Adding to the struggle, any in-game death becomes permanent, ending the player's life in the real world. While Kazuto Kirito Kirigaya was fortunate enough to be a beta-tester for the game, he quickly finds that despite his advantages, he cannot overcome SAO's challenges alone. Teaming up with Asuna Yuuki and other talented players, Kirito makes an effort to face the seemingly insurmountable trials head-on. But with difficult bosses and threatening dark cults impeding his progress, Kirito finds that such tasks are much easier said than done.
