Tidal Clan

Tidal Clan is a Player Killing guild in the MMORPG Elder Tale.

Overview
Tidal Clan is one of the PK guilds that gained notoriety around Akihabara after the Catastrophe. They ambush players around Akihabara in order to loot the items and gold they drop after their death.

They are expanded on slightly in Log Horizon: West Wind Brigade, where Magus persuaded them to go PKing. To combat the rising number of PKs around Akiba, the West Wind Brigade members lead the members of Tidal Clan, Canossa, and Blue Impact into a trap, where Soujiro Seta and Isaac slaughter them.
