To make antibiotics, Senku and his kingdom need to obtain sulfuric acid from a fountain of the stuff. The team goes prepared, but there’s no guarantee that they’ll make it back alive.
I'll risk my life as many times 
as it takes to save Ruri-nee.
.سأجازف بحياتي مهما تطلب الأمر لإنقاذ أختي روري
Für Ruris Rettung setze ich
bereitwillig mein Leben aufs Spiel.
Arriesgaré mi vida cuanto haga falta
para salvarla.
Arriesgaré mi vida cuanto haga falta
para salvarla.
Je suis prête à risquer ma vie
pour sauver Ruri !
Se la posta in gioco è salvare Ruri,
non ho problemi a mettere in gioco la mia vita!
Eu vou arriscar minha vida quantas vezes
forem necessárias para salvar a vida da Ruri.
Ради спасения сестрицы
я готова и жизнью рискнуть!
