• Moderate
  • The first two seasons contain minimal amounts of actual blood. With Season 3 (Alicization), however, this season projects a darker narrative and contains a more blood and is more violent than the other seasons.
  • Alicization is much darker than seasons 1 and 2, and it shows in its violence, being much more violent, explicit and graphic.
  • Season 3 is more graphic and show actual blood and not pixels like Season 1 and 2
  • Sword Art Online takes place in the future within a virtual reality video game. There is no blood shown when people are stabbed or slashed at, the only thing that shows up is some red pixels that represent where a player was cut, or fatally injured. Therefore, one should keep in mind that the violent content here is virtual unless stated otherwise.
  • The storyline for episodes 1-14 goes as follows: 10,000 people are trapped in a virtual reality video game, and the only way they can escape is by completing the game, because if they die in-game, they will die in real life. It's a rather intense premise and it is said that approximately 4000 players die as a result.
  • There are near-constant battle sequences between monsters and players. These scenes can be fairly intense.
  • A few suicides (they jump off a ledge and then burst into pixels as they hit the ground).
  • Episodes 15-25 follow a similar premise as the first 14, but players do not actually die if they do in-game.
  • A boy's hand is chopped off with no blood (in the game). He then takes his other hand and lunges it through another man. He later has his hand regenerated (since it's in a game).
  • In Alicization War Of Underworld, a main character has their arm chopped off and is then stabbed through the head with a spear. An extreme amount of blood sprays everywhere
  • In season 4 part , at the end, a character feels an immense ammount of pain in their eye and proceeds to pull it out of their eye, there was a lot of blood and kind of hurt to watch. (Some people makes little painful to watch).
  • The characters use "Pain Absorbers" in-game so as to mitigate the amount of pain they feel when they are stabbed, cut, etc. so as to prevent any actual harm from coming to their real-life bodies. In episode 24 however, the main antagonist impales Kirito with a large sword and proceeds to slowly turn off the Pain Absorber, causing him more and more pain from the wound. However, Kirito eventually removes the sword from his chest, healing the wound, and then deactivates the Pain Absorber completely. He gets his revenge on the main antagonist by cutting off the latter's forearm, slicing him in half, and impaling his head on the sword, all while the antagonist screams in agony. This is not particularly graphic, but pixelated blood is shown bursting out of the wounds. The brutality is justified by the fact that the antagonist had just tried to sexually assault Asuna, Kirito's lover, and so the over-the-top execution is intended to satisfy the aggravation of both the viewers and Kirito himself.
  • In the real world, a boy is attacked by a sadistic man with a knife, who tries to kill him. His cheek gets cut. The two struggle before the boy ends up on top of the man with the knife to his throat. He is tempted to kill the man, but instead leaves him unconscious.
  • In season 2, multiple fights occur through out this season as the game is a VRMMOFPS (Virtual-Reality Massively Multiplayer Online First Person Shooter) it deals with many gunfights. Then, in the real world, a fight occurs between 2 boys as one becomes pinned and the other punches the pinned boy's face. The pinned boy then gets inject with a medicine (will not tell you for the sake of the story itself)
  • In season 2 episode 3, a girl is seen having a history of a brutal shoot out in her past where she killed a robber with a gun he dropped. This is repeatedly shown through out the show and may upset some viewers. This is revisited in episode 14.5 and a part of the shootout could be seen in the intro.
