You won't be able to live 
without Yukako Yamagishi.
لن تتمكّن من العيش من دون يوكاكو ياماغيشي
Dass du nicht ohne mich,
Yukako Yamagishi, leben kannst.
No podrás vivir sin mí.
No podrás vivir sin mí.
et que tu ne peux pas
vivre sans moi.
Non riuscirai a vivere
senza Yukako Yamagishi.
e que é incapaz de viver
sem Yukako Yamagishi.
