Criminal pointing gun at Kirito, he´s done for if nobody intervenes.
Silica: K-Kirito ... I-if I dont do something ... he saved Pina ... he never looked at me as more than a friend, but ... now I can prove to him what I really felt ... Kirito!
Shinon: N-no! I won´t let anybody hurt the person that saved me from despair. Screw you, scumbag. Kirito!
Liz: Nobody cares about me. But he was the only one to at least spend some time with me. Well, at least that way my suicide will be disguised as saving his life. Win-win situation. Ahem, Kirito!
