Sabertooth (Deadskin)

Sabertooth (セイバートゥース Seibaa Tuusu, 剣咬の虎, literally meaning "Sword-bite Tiger") is currently the most powerful guild in Kingdom of Fiore.

History
Before the incident on Tenrou Island, Sabertooth was not a well known or powerful guild, but in the last seven years they recruited five new members, which dramatically increased the guild's strength, making them the number one guild in Fiore.
