Zeldys

Zeldys (also spelled Zeldus or Zerudyusu in some translations) is a supporting character in Log Horizon, particularly prominent in the light novels and later adaptations.

He is a Ritian (one of the game's races) Cleric and serves as one of the Ten Seats (high-ranking council members) of Plant Hwyaden, the dominant guild controlling the Minami (Osaka) server area. He's ranked as the third seat in their hierarchy.

Zeldys is portrayed as a true efficiency-obsessed gamer who prioritizes optimization, growth, and results above all else. In his pre-Catastrophe life, he enjoyed strategy and simulation games (like SimCity or Factorio-style titles), and he's willing to take extreme measures if it means achieving maximum efficiency.

His unique Overskill is Mana Breeder, which plays a key role in helping restart the transport gate in Minami by generating or managing massive amounts of mana.

He's voiced by Yūya Uchida in the anime.
