Eisel

Eisel (also spelled Aizel or Eizel in some translations) is a supporting character in Log Horizon, particularly associated with the Crescent Moon Alliance guild in Akiba.

He's a Half-Alv race Sorcerer (a magic-focused DPS class) with a Miner subclass. In the guild, he serves as the leader of the purchasing/procurement team and is one of the few male members alongside characters like Shouryuu and Hien. He's described as relatively tall and often gets assigned miscellaneous or support tasks.

In the anime adaptation (especially noticeable in Season 1), he appears as part of Marielle's guild crew during events like discussions about player-killers (PKs), supply issues, and preparations for expeditions (such as the trip toward Susukino). His real-world identity is a 19-year-old university student named Keiichirou.

He's not a major protagonist but fits into the guild's background operations and everyday Adventurer life in the trapped Elder Tale world.
