Bayroad

Bayroad (베이로드, Bae’ee’rohdeu) is the name of a secretive ‘pit’ said to be hidden somewhere in the Tower. However, that does not mean actual dogs are pitted against each other in this pit; ‘special fighters’ are the ones fighting, and they are collectively referred to as ‘Pitbulls.’

A characteristic of Bayroad is the long and straight appearance of its arena. Pitbulls run out onto the arena from both sides and fight until one drops dead. It is said that even if one tries to escape, a terrible bed of blades waits at the end. Because the shape of this arena resembles a road, it was named Bayroad, ‘the road where pitbulls bark.’

The process through which these ‘Pitbulls’ are ‘created’ is very interesting. They are born through "Blood Fusion" which is forbidden in the Tower. Blood Fusion is the process in which a specific ‘something’ from a Family possessing great power is mixed into a baby in its embryonic or fetal stages to grant it said power.

(There are not many who know how to carry out Blood Fusion, and because its practice is absolutely forbidden in the Tower, even those who do know it have mostly been murdered or have gone missing.)

Children who manage the very small probability of surviving Blood Fusion (Most embryos and fetuses cannot endure the side effects and die) are raised to become tools of entertainment to entertain those who come to the pit, and so these children grow to fight as Pitbulls.
