As Nova heard that Dixon's Master, who was a being above Immortal Stage, was coming here, his pupils constricted.
'Shit...my plan may be ruined.' Was the first thought of Nova.
And he thought so because he wanted Rinosus to take over this Demon Region without trouble.
If he wanted his Human Region to be safe, then this was the best option. As Rinosus was
controlled by him, it would've been much easier to make the demons listen to him, rather than Nova.
Let's say that Nova defeated the demon's higher-ups, would the rest of the demons follow him? Of course not!
While a part of them may be willing to follow him, the vast majority would run and seek refuge in another Region.
Also, the Demon Zone may not take this well and even launch an attack towards Nova's Human Region.
Ideally, Rinosus must take control of the Demon Region, but now it seems that there's a big problem with Nova's plan.
