Ep. 15: King of the Deep Sea (深海の王 Shinkai no ō) is the fifteenth episode of Kishiryu Sentai Ryusoulger. It features the full debut of Kishiryu MosaRex and the first appearance of Canalo's sister Oto.


Canalo's little sister Oto suddenly appears on the surface after hearing that Canalo is searching for a bride on land. Canalo tries to return her to the sea, as he is concerned with the fact that she has never been on land before. Canalo and Koh suddenly rush to the city after a Minosaur starts to attack. However, the Minosaur's powers cause the Ryusoulgers to separate amongst themselves. Just then, Kureon suddenly appears before Red and Gold and takes Oto as a hostage. Kureon demands that if they want her set free then Canalo must attack the Ryusoulgers.
