This anime series is for me a small masterpiece, it contains many characteristics of classic anime, a pinch of harem, some scenes a little hentai, a hero, a heroine, a fantasy world, a little sister in love, fighting and action.
It is based on a series of light novels and is in my opinion really enjoyable to follow. The first season is my favorite but I liked the others as well. The story rounds around kirito, a beta tester of an online game, connecting to the game on the official start day, he and the other players discover that it is impossible to log out and that the game master makes it impossible for him to exit on pain of death, and they are therefore trapped in the game, the only way out is to finish it and if you die during the game you also die in reality.
all pictures are taken from my monitor.
But in this world there are his kirito and Asuna two skilled swordsmen who want to get out of the game at all costs. The first has more than one setting, the first Sao, from which the name of the series is drawn, the second is alfehim, a more enchanted setting than the first, where Kirito will have to work to save Asuna and where he will meet new characters in reality he is not so far away indeed very close.
It's really a great anime perfect for all people and I think for all ages too.
I especially love the first part of the first season but also the fairy reign it's nice.
If you have not watch it, watch it soon!!
