Sword Art Online: Alicization
Three friends decide to venture to the fabled cave in the End Mountains. Both Kirito and Alice alleviate Eugeo's fear that they might be violating the Taboo Index, the laws of their world, and soon enough, it's time for them to set off.
Along with Alice, Kirito reaches the communal bathing area on the 90th floor. There, they find the Integrity Knight Commander, Bercouli, who's been turned into stone by Chudelkin.
Standing in Kirito and Alice's way is Eugeo, who's undergone the Synthesis Ritual and become an Integrity Knight. Kirito is rattled, until Alice admonishes him into resolving to fight Eugeo with everything he's got.
The top floor of the Central Cathedral. Kirito, Eugeo, and Alice are face to face with Administrator at last. But Chudelkin uses the Sacred Arts to transforms himself into a giant clown and attacks them.
Cardinal appears on the top floor of the Central Cathedral for a showdown with her bitter foe. She makes a move to attain her objective as a program for maintaining order only to see the fallen Sword Golem rise up again to thwart her.
Carrying the hopes of Cardinal, Eugeo, and Alice in his heart, Kirito gets on his feet yet again. To defeat the most powerful entity, the Administrator, Kirito wills himself to visualize the Black Swordsman, the top player who cleared SAO.
