Killberos (aka the Three Canines) is a "guard tribe" which was lead by Gwangnam when he was alive. Its main membership was by youngsters who live near Kana and look up to Gwangnam.
The organisation was established by an ex-member of Gusa secret organisation with members being children in the orphanage that the ex-member set up. The original Killberos emblem had fangs pointing downwards, being an action tribe.
The Killberos safe house is where the Canine Conference and also Gwangnam's funeral were held.
Killberos is feared by the Nine Snake Family due to a incident in which Gwangnam being the leader of Killberos smashed the Nine Snake Family's Tail's office when he was looking for Jaehwa.
The Killberos code of conduct laid down by Gwangnam has rules:
- Indeed, we should enjoy our lives.
- Indeed, let's not fight amongst friends.
- Indeed, let's not cross the line.
- Let's not do v-ery bad things.
