Fuurinkazan

Fuurinkazan (風林火山) is one of the clearing guilds in «Sword Art Online», with Klein as their guild leader.

Background
The Fuurinkazan is a guild started by Klein and a group of his friends from the real world. They had waited in line for a long time in order for each of them to obtain one of the 10,000 copies of the game. All of the members of Fuurinkazen have known each other since before SAO started. Klein had protected and guided all of them, until all of them had become capable players on the front-lines. They have never lost a single member in combat.

Aincrad Arc
Klein first mentions he was leader of the guild in a previous game to Kirito as Kirito leaves him behind in the starting city.

Red-nosed Reindeer (Aincrad 46th Floor, December 2023)
The Fuurinkazan helps to fend off the «Divine Dragon Alliance» while Kirito faces the boss of the Christmas event, «Nicholas the Renegade».

Year II
Kirito and Asuna bump into Klein and the Fuurinkazan in the dungeons of the 74th floor. They also find that members from «The Army» are attempting to handle the boss without a raid party. When Asuna and Kirito rush in to save the beleaguered party, the guild follows closely behind. While Klein and Asuna hold The Gleam Eyes off for ten seconds allowing Kirito to equip his Dual Blades skill, the other members take the remaining Army players out of the way, saving them.

Fairy Dance Arc
Fuurinkazan has been reformed in Alfheim, but with the exception of Klein, none of the members have made any appearances.

Trivia

 * The name of the guild is likely a reference to the battle standard used by Takeda Shungen's, quoting Sun Tzu's "The Art of War". "Move as swift as wind, stay as silent as a forest, attack as fierce as fire, be an undefeatable defense like a mountain."
