Seiyuu was a guild comprised solely of just seiyuus alone. Despite the number of members being low in Seiyuu, this guild has countless vanguard guilds who worked with them.
Seiyuu's numbers are low in terms of members, and so are their abilities too. However, the guild's ability to move people is considered to be number one in YGGDRASIL.
- This guild's name is only mentioned in the Web Novel so far.
