Since Floor 1, she has joined up with Kirito on her quest to conquer SAO. Now that she has become accustomed to the world of gaming, Asuna has become a top player among the assault groups.

Along with Asuna, he advances the assault of SAO.
In addition to being a skilled swordmaster, he has a wealth of knowledge and experience as a former beta tester. But for that reason, some players shun him.

A former beta tester like Kirito, Mito wields a giant scythe as her weapon.
She attended the same school as her best friend Asuna, and the two formed a 2-person party at the start of SAO.

A skilled informant and a familiar face to Kirito and Asuna, she is called "Argo the Rat" because of the whisker-like makeup on her cheeks.
