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.
You've never won against me once!
!أنت لم تهزمني ولم مرة
Du hast noch nie gegen mich gewonnen.
Inwiefern willst du ein anderer sein?
Nunca me has ganado.
Nunca me has ganado.
Tu m’as jamais vaincu une seule fois,
comment tu pourrais avoir changé ?
Sei sempre l'uomo che non ha mai vinto
 contro di me, cos'avresti di diverso?!
Você jamais me vencerá!
Ты ещё ни разу меня не побеждал.
Не вижу никаких перемен!
