第 4 集: 眾人進入貿易城市，Ruuji 遭竊賊奪走 Murasame Liger。

4

The group arrives at a trade city. While Mii and Ra Kan go to scout out the area, Ruuji takes Murasame Liger into the city by himself, hoping to find a Generator mechanic. He is treated to lunch by a girl named Kotona, and while he is away from his Zoid it is stolen by a gang of thieves. Kotona reveals that she had planned all along to use the Liger as bait so she could catch the thieves. They use Kotona's bird-type Zoid, Rainbow Jerk, to catch up with the gang and recover Murasame Liger. (Source: Wikipedia)
