Tsukasa has learned about the cave where the nitric acid is collected. The race is on between Senku and Tsukasa to restore humanity in their respective visions.
It's because of you that I was 
able to stay alive all this time.
.استطعت البقاء حيًّا كلّ هذه المدة بفضلك
Weil du da warst,
konnte ich bis heute überleben.
Pude mantenerme vivo
gracias a que existías.
Pude mantenerme vivo
gracias a que tú existías.
C’est grâce à toi
si j’ai pu survivre…
Grazie alla presenza di Yuzuriha,
Por sua causa, eu continuei
vivo todo esse tempo, Yuzuriha.
Лишь благодаря тебе я смог выжить.
