History and Description
Not much known about Gatoya's history, but it is very well-known to hold prisoners by a Shou who should be in charge by the government, much like Muroya. very. Currently Gatoya is a very desolate and grim island that gives unfair judgement onto prisoners, so much as it received the name, "Hell at the End of the World" from public reception. However, Gatoya wasn't like this before as it used to be a decent prison with fair judgement, but due to the betrayal that Tsutsuga received, he made Gatoya into a living hell.
