Kenshin and the rest fell underground and had no idea of what to do. Meanwhile Misanagi and the Black Knights enter the path way and begin to move toward the divine medicine. Later on, gas was leaking in and in less than half an hour Kenshin and the others would be goners. Sanosuke punched the wall and water came rushing out, because of that they were able to escape. Outside Yutaro found someone, it was a ninja named Kaita. He was injured and was going to die if not treated. Yutaro worked hard and treated Kaita's wounds, he woke up and helped them by using a shortcut so they could get caught up. Finally getting inside there were three guards, Zan, Ren and Baku, they attacked everyone and Ren was able to cancel out one of Kenshin's attack. (thetvdb.com)
