I am a princess, moreover, I am a fool of a princess.

Born in the imperial palace, my appearance is as average as that of the white radish and cabbages in the fields. Throughout the four seasons of the year, my face is always displaying a dull expression, eyes forever shrouded in haze.

But in reality, I know of the secrets within this palace.

Including hers, his, and theirs.

Just leisurely living my days comfortably in the palace like this, I firmly believe I can continue to play dumb to the end.

Taking your hand, dragging you away. Not leaving you say? Very well, close the doors and release the hounds. (Expressionless face)

The strongest hero of humanity, Kim Sung Bin.

Kieran Silver is a young man who suffered from the deceit of his superiors. His outstanding talents and exceptional prospects to climb to the top of Zenith Online dismayed his superiors.

They invoked their influence to suppress his uprising, ultimately causing his demise. However, rather than perish, Kieran Silver receives a second chance.

A chance to dethrone one of the top 10 guilds, Golden Brigade. An opportunity to create an immortal legacy that would forever live on in players' minds. The ability to reach the zenith in both worlds!

However, as he is reborn, Kieran notices a few things that are different from what he remembered. Could it be that he has gone back in time, or is there an even deeper explanation and a larger power at play?

These questions will be answered, whether forcibly or inadvertently, as Kieran explores a seemingly driving force.

The advent of the Legendary Berserker begins!
