Owl Of The Night

There are 3 races on 3 separated islands to protect their own race from decreasing. If another race enters other race's island will be immediately punished for crossing the 1st rule of what the First Ancestors created to make peace.
There's also another bigger island for every race to understand each other, but a gang was started by slowly killing everyone there to become stronger on getting more blood from their victim.

So the 3 races made a deal to stop the gang and go back to the normal life they used to have, but it was all still not a complete mission for them. Mortal races decrease a lot on the bigger island named "ParadiseFE," which never completes the deal.

The 24th Leader of the Paradise came up with the idea of creating a Special Force to protect the races from decreasing. It was never easy for the group to stop the gang.

Until a group of unexpected college students and one unknown girl gets kidnapped to become the Special Force to protect the 4 layers of the ParadiseFE. Everything was going just as planned until a big event of raid. It was brutal and miserable for the group to stop the raid until a group of unknowns helped the Special Force defeat the raiders and find the person who's behind all these brutality issues everywhere.

Stay tuned to find out more.
