I felt all of the character's stories as to why they joined Rugal were the same with feeling powerless from preventing corruption or a loved one died so feel guilt. Can't lie I wished we see more of Gwang Chul as I would class him as a half-robot. Gi beom I fell in love for and sympathized with when the eyes got out of control and the situation with his life as he tormented himself over it.
The story made little sense so actions seemed irrational and a little crazy and throughout the whole series hated the chief as he didn't seem to care about anyone's suffering he only wanted Argos to die out and yet the chairman we learn is alive. They should've left it at that as their new everyday lives were dull and we only see what Gi beom is doing.
The fight scenes were nothing special as you knew who was going to win before it even started but were good fun
