Yeah, its totally like SAO, because he goes Solo.
But wait for it, theres more. Its also Like Black Clover, Fairy Tail, Naruto, Bleach, Dragon Ball,Overlord, Goblin Slayer, Shield Hero, Game of Thrones, The Witcher, Harry Potter, Attack on Titan and more!
Black clover because he uses "dark powers",Fairy tail because he has a friend, Naruto because he began weak, Bleach because he has a sister, Dragon ball because he gets stronger everytime he fights
Overlord because he can summon minions, Goblin Slayer because there's Orcs, Shield Hero because someone uses a Shield, Game of thrones because people die Ima rite? Witcher because he kills Monsters
Harry Potter because Magic and Attack on Titan because theres someone who drinks water in AOT therefore, Its just like AOT.
