Information about the character

The tower. A structure made by God to let living creatures alike climb it and achieve their dreams, their desires.
Climbers chosen by the tower are called regulars and the ones who open the door by themselves... Irregulars.
Irregulars, when they enter the tower chaos is insured to happen.

Watch the anime or read the webtoon if you don't want spoilers for the series.
I used the webtoon instead of the anime to write this story.
Also none of these pictures are mine.
