I was summoned from heaven, but I have a younger sister….
Hearing the name Selka, the Integrity Knight, Alice, becomes visibly distraught, and Kirito makes up his mind to restore Alice’s lost memories.
To help Alice Synthesis Thirty recall that she was once Alice Zuberg, and to let her know the true reason why she became an Integrity Knight, Kirito starts to tell her about the path he and Eugeo had traveled till now. About how Eugeo, after meeting Kirito, hoped to rescue his childhood friend Alice, despite his status as a mere villager. How they had both left for the central city to become knights. And how somewhere along the way, they’d found themselves getting closer and closer to the hidden truth about this virtual world they lived in – the Underworld.
