Mamoru Kariya (狩谷 守, Kariya Mamoru) is a man who transformed into the Submarine Malgam (サブマリンマルガム, Sabumarin Marugamu) with Deepmariner.
History[]
While Rinne was finished collecting Pilets, Kariya was secretly following her, seeing her as his woman. He was already fused with a Chemy, Deepmariner, which was influenced by his malice of his obsessive love to Rinne. With his newfound abilities, he continues to stalk Rinne undetected, as he submerged under the ground as if it were a body of water, and followed her under his sight via his periscope eye.
After Hotaro defeated Takemoto, he reappeared, still as a Malgam, and ambushed her, Houtarou, and Minato by sinking them into the ground. He was about to abduct Rinne, until Supana blasted him with his Valvarusher, then transforms into Valvarad.
Angered by the interruption, Kariya talked back against Supana for interrupting his “love”, to which Supana, finds it as a bad joke. Angered by the insult, the Malgam tells him to shut up and began firing his torpedoes. But Supana stopped them by inserting Gutsshovel and equips a power arm to crush them.
Kariya tried to immobilize Supana by liquifying the whole ground he was standing on, but he used Gekiocopter and flies away and attacked him with his Valvara Break. The stalker was defeated as he reverts back to normal and Supana collecting Deepmariner.
He is not seen after his defeat, but it is implied that his memories were erased and he was left for the police and arrested along with Takemoto.
After a while, Clotho kidnapped him from prison under the request of the Dark King Gaelijah, who intended to use him as a test subject of Malgams made without Chemies via the remaining essence within him. But he was defeated by Hotarou and Rinne and was possibly left for the police and arrested.

Personality[]
Kariya is a creepy, mentally unstable, and murderous individual who had an unhealthy obsession with any women he sees, before killing them. With Rinne Kudo especially, he started calling her his love and constantly following her undetected. His obsession was so strong that he refused to let anyone get in his way, including Rinne's allies.
But he was shown to be easily prone to anger and does not take kind to insults, as seen when Supana described his "love" for Rinne an unfunny joke.
