The final battle against the Dark Territory drags on, as players from all over the world flood the Underworld's servers and plunge the Human Empire into utter chaos. Asuna Yuuki and her friends defend their new allies with everything they have, but their numbers are falling. Meanwhile, Alice Zuberg heads toward the World's End Altar while Gabriel "Vecta" Miller relentlessly pursues her.

Meanwhile, members of Rath strategize a plan in an attempt to restore Kirito's damaged fluctlight. However, the intruders occupying the main control room have other plans. Surrounded by death and despair, when all hope seems to be lost, one voice reaches out to Kirito—a familiar one saying, "I will always be by your side."

Sword Art Online: Alicization - War of Underworld 2nd Season is the epic conclusion to Akihiko Kayaba's dream of creating artificial human intelligence. Now it is up to Kirito and his friends to protect this collapsing world from the people that still think it is just a game.

“Jesus shall come again in glory to judge the living and the dead; and his kingdom shall have no end."
-Corinthians 15:23

I used to be an atheist until I watched Sword Art Online: Alicization: War of Underworld Part 2. History has proven Jesus was a real man, but the second coming of Christ was merely a myth to me. I never truly believed Christ would return from the heavens to liberate us… until now. Reki Kawahara has created the final chapter of the Bible. This tale rivals Shakespeare, Dante’s Divine Comedy, and The Odyssea. It is the most spectacular writing I have seen in the read more

(Note: This review covers both seasons of SAO War of Underworld, and also contains spoilers for Samurai Jack Season 5)
The end of the nine volume “epic” Alicization, the end of SAO’s original web novel, and the last of the original flawed sect. While SAO rants have been done to death on the problematic issues, including from me, I want to structure this review in a slightly different way. War of the Underworld positions itself as the end all be all of everything the series has culminated towards for nearly a decade, and it has the presentation to potentially make it an impressive achievement, but not read more

I have to be straight with you all - I'm just floored by how many people blindly love everything SAO. I absolutely love the Aincrad arc, and Alfheim was pretty enjoyable. S2 was fine, Alicization was pretty good imo. They all have their flaws (and boy are there a lot of them). But this? My God I cannot fathom how anyone is rating this higher than a 5, which is much higher than I'm willing to rate it.

** There are some spoilers in here, so read at your own risk. No major plot spoilers, though! **

SAO's franchise has always been full of disapproval babbles between the anime fans, we can look that in the continue hate and rants that we can find in every place. However, even if it is hard to accept for several fans, the light novel is considered the best of Japan's decade, where it matters. One of the arcs from that light novel is titled Alicization that concludes with these eleven episodes and that for me, it is probable the best part of SAO's plot until this date leaving aside the new arc (Unital Ring) that is being published right now.

The story follows the read more
