>>280283598Shizuka actively wanting to fuck Takashi is what gives her the edge over Yuko for me. They're both fine titcows, but Yuko seems to have no sex drive at all. There's even been a timeskip in Triage-X where she's over 30 now, and as far as I know she's still a virgin.
The idea of a body like that going to waste is criminal to me. On the other hand, Shizuka actively wants someone to put a baby in her.
