SENTINEL (English)

December 21, 2012. The day the Earth drowned in a panic for the first time by the appearance of monster. Since then, many cities around the world have been attacked periodically by various of the evil creatures with their terrifying powers. The United Nations has established a special division to combat and study the monsters in order to protect humanity, the United Nations Monster Counteraction (UNMC).

Ray Davidson, a soldier with strong sense of justice and desire to protect the weak, got promoted and joined the UNMC. But like everyone else, he has his own secrets. Since he lost his parents to a monster, Ray has somehow wield mysterious superpower that keeps growing within him.

Not only that. Ray's morals are further tested after his direct encounter with a some kind of superhero, the only one in the world. A superhero who is too powerful that he can defeat any monster with just a single punch! His lone actions in destroying many powerful monsters has become a help to the UNMC for several years (though he never intended to). The problem is, this man also has been known for being lazy and negligent, which made him have a bad reputation in the public!

Thus begins Ray's journey to discover the truth regarding his powers. To define his true self. Not only as a human, but also something more. For the sake of protecting the world from evil...

...with the help of that superhero, sometimes.
