Distributes the Lock Seeds to the Beat Riders. He's the one that makes the Inves Games possible.

He's in total cahoots with the Yggdrasill Corporation. It appears that Kureshima Takatora is his direct supervisor.

Trivia

• The A in Yggdrasill forms the trunk of the logo's giant tree. Their base is Yggdrasill Tower which is a building shaped like a giant tree.
• Yggdrasill has commercial/propaganda similar to Smart Brain's commercials in Faiz.
• Apparently Yggdrasill's presence in the town has only been within the last 20 years. Before, it was a small town like any other found in Japan, but that all changed when Yggdrasill moved in.
