Corona

Corona (コロナ Korona) is a Hell island located deep underground and amidst the ocean of magma known to Hell islanders as the Dark Sea. Like their brethren Hellpieans, Coronans appear to take on the likeness of demonic humanoids; albeit, there are some subtle differences between the Coronans and Hellpieans.

Corona is connected to the Blue Sea above via a winding maze of subterranean tunnels that snake through the insides of the Red Line. At the end of the tunnel is a cliff side cave, which overlooks the ocean of the East Blue. From there, one can enter and exit Corona.

Much like other Hell islands, the existence of Corona is unbeknownst to many outsiders; even being considered a myth or joke by some.
