Kisaragi's death is a bad one - you can almost hear the neck tendons snap.
That said, the sounds do bring home the horror the way the manga does not. Kisaragi dies either way, but the image on the page almost looks like Lucy is lifting her head off like some kind of sick/weird magic trick, while Nana almost looks like her limbs are being whisked off somewhere. Mariko's arm is almost like 'Huh?' in C53, while her legs in C70 really bring home the pain. Even Kanae's manga death scene requires a double-take, even if you know her fate. At some point, LO picked up his game, and the early art shows how much he needed to.
Hi. Are you sure you do not confuse Kanae with Kaede? Sorry if you do not. Some people at youtube confuse the two different girls. Kanae is a younger sister of Kouta and Kaede is the real name of Lucy and the heroin.
