All that’s needed to make antibiotics is alcohol. The best way to get some is to win the Grand Bout, which the Senku and his kingdom will also need to do in order to keep Magma away from Ruri and give her the drug.
But I'm the only one who can 
save her. I'm the fastest.
.لكني الوحيدة القادرة على إنقاذها لأنّي الأسرع
Doch nur ich bin schnell genug,
um sie retten zu können!
Mais je suis la plus rapide,
seule moi peux la sauver !
Ma Suika posso salvarla solo io, la più veloce di tutti!
Mas eu sou a única que pode
salvá-la! Eu sou a mais rápida!
Так ведь я самая быстрая!
Кому ещё спасать Суйку?
