Eldmed Ditigeon

Eldmed Ditigeon (also known as the Conflagration King or Blaze Death King) is a powerful ancient demon from the Mythical Age and one of the Four Evil Kings, who were among the strongest demonic subordinates under Anos Voldigoad in the past (second only to Anos himself).

In the anime adaptation (particularly prominent in Season 2), he appears as the new homeroom teacher for Anos' class (Class 1-2) at the Demon King Academy. He initially comes across as eccentric, suspicious-looking, and unconventional, which makes the noble students skeptical of him as a teacher.

He's bold, cocky, and has an intense, almost obsessive fixation on strength—especially Anos'. Eldmed is driven by a desire to push Anos to his absolute limits, test how far the Demon King can grow, and witness him surpass even greater heights. He praises those he deems worthy (like powerful opponents or Anos in his younger form) while looking down on the weak.

Overall, he's a chaotic, battle-hungry figure who creates challenges and strong adversaries to spice things up for Anos, blending a mentor-like role with his own thrill-seeking agenda.
