18화: 히요가 이끄는 츠카사의 부대가 센쿠의 신무기를 맞으며 마을을 공격한다

18

A group of Tsukasa's army, led by a man named Hyoga, approaches the village and beats down Kinro. With Ginro unwilling to cut down the bridge to the village with Kinro still on it, Senku, with the aid of Gen and Magma, convinces Hyoga's group that they've already produced guns, forcing them to retreat. Three days later, during a storm where guns would be unusable, Hyoga's team attacked again, only to discover that Senku and the villagers had managed to produce katanas. Although Hyoga proves to be a powerful foe with his spear technique, the spear breaks thanks to some sneaky sabotage by Gen. (Source: Wikipedia)
