Sword Art Online: Alicization has kicked off a brand new arc with the second cour of the third season of the series, and with a new arc comes a brand new opening and ending theme sequence.

Sword Art Online is gearing up for a more intense, battle heavy arc in its third season and that's teased a bit with the new opening theme sequence. Now that Kirito and Eugeo have essentially declared war on Administrator in the hopes of restoring the Underworld, saving Alice, and getting him home, the two of them are going to facing off against new and fierce opponents.
The battle-heavy arc gets teased with some awesome animated sequences as Kirito and Eugeo make their way to the top of the Central Cathedral, but this is all only a tease of what's to come as the third season of the series continues.
If you have yet to catch the new season of the series yourself, Sword Art Online: Alicization can currently be found streaming on Crunchyroll, Funimation, and Hulu. The series is officially described as such:0comments

Her name is Alice. And it is a name that must never be forgotten...”
