Senku, Taiju and Yuzuriha head to Hakone to collect sulfur for gunpowder, which they’ll need to fight Tsukasa. They accidentally set off an explosion, which attracts some unexpected attention.
As long as we have a gunpowder 
weapon, we have leverage.
.لدينا اليد العليا ما دمنا نملك سلاح البارود
Mit Schießpulverwaffen
haben wir die Überhand.
Mientras tengamos pólvora,
tendremos ventaja.
Mientras tengamos pólvora,
tendremos ventaja.
Avec des armes à feu,
on aura l’avantage.
E con un'arma come la polvere da sparo,
saremo in vantaggio.
Enquanto tiver uma arma
de fogo, teremos vantagem.
А с порохом у нас
будет и преимущество.
