THE NEW GATE

When an online game turns real, trapping its players in its virtual space, the strongest of them, Shin, rises up to put a stop to the madness. But just moments after defeating the game’s final boss, Origin, and freeing everyone, Shin is transported 500 years into the future of the in-game world. Armed with unrivaled strength, the young swordsman embarks on a legendary journey. (Source: Crunchyroll) — Description from AniList community (anilist.co).
