Sinjin and Diablos stage is Abandon All Hope. The stage looks sinister. The background is all purple and black with what appears to be meteors hurling into the background. The stage itself has weird gate like pillars and other buildings and statues. There is a small pavement used as the battleground and it stretches for a great leangth inbetween the pavements their appears to be green fire coming out of it. The stage looks very barren compared to the others.
