Twenty years ago, mysterious "Rifts" appeared in the sky, connecting the otherworld to reality. Since that day, monsters have appeared all over the world, causing immense damage to humanity.

The government dubbed them 'Hunters' and established a professional Hunter system. - Hunter Ranks - Rank: F → E → D → C → B → A → S → SS → EX F-Rank Newbie level, just awakened.

The world has changed. Ten years ago, humanity faced 'That Day.' The sky split, space tore open, and something began to pour out from the black rifts.
Monsters that couldn't even be named. People called those gaps Gates, the things coming out of them Monsters, and those who fought against them Hunters.
But the Gates did not disappear. Instead, their numbers grew, their forms became more unstable, and they are now classified into eight stages, from White to Crystal.
And now— Before you, it has opened.
In this place, what is your role?
