Unified Soviet Red Assault Command Marine

"When the Soviets first reached Sequin Land, they would make something that would be for the Unified Soviet Red Assault Command Navy, which would frightened anyone that swim into their way. Terrorizing those who fight against the USRAC and all of her allies. Not if I have to use my wits to take 'em all off."

--Su Ji-Hoon, Capturing Giga Mermaid
