The New Gate

If you hope something groundbreaking from the likes of anime's with this kind of title, I'll be blunt, there's nothing "new" about "The New Gate." The best it can be is being a blend between Sword Art Online (SOA) and any isekai anime like "In Another World with My Smartphone."

The main character is trapped in a game, which, unlike SOA, is not filled with any other gamers beside the main character. On the other hand, he is in a usual fantasy world where there is battle between the hero and the demon lord.

This will be your daily "overpowered character in another world" anime, and you won't complain because it's refreshing and entertaining. The characters are not bad, while anything else is pretty much forgettable.
