Sword Art Online: Alicization

The two girls introduce themselves as Linel and Fizel, two novices studying at the cathedral, but just as they approach Kirito and Eugeo, they stab them with poisoned daggers, revealing themselves as Integrity Knights. To prove their value to the other Knights, Linel and Fizel carry the immobilized Kirito and Eugeo all the way to the 50th floor, where Fanatio, vice-commander of the Integrity Knights, awaits them. Upon arriving there, Kirito, revealing that he saw through their scheme and had taken measures to protect himself, uses the same daggers to restrain them, and confronts Fanatio alone until Eugeo recovers. Eugeo then uses his "Perfect Weapon Control Arts" to immobilize the knights.
