Donadrond

Donadrond is the trainer of the Adventurer's Guild (Alessa Branch). Whenever someone who seems too young and inexperienced tries to register to become an adventurer, Donadrond becomes the one responsible of giving said youngling a severe beating to prevent him/her from registering as an adventurer and potentially dying on a dungeon.

Personality
Dondrond's appearance matches up with his personality. He is casual and direct, with a veteran attitude, and good-natured.

Appearance
Towering over two meters tall, Donadrond is an intimidating man. Protruding from his head are two horns, and his body is sturdy and muscled. In battle form, he wields a gigantic battleaxe and black, spiked armor "which looked like it came right out of the Middle Ages."

Abilities
Donadrond's strength is so high he could easily outmuscle a Lesser Wyvern.

Fran
Despite his tough appearance, Fran does not feel intimidated at all when first confronting him. In the manga, she is somewhat shocked by the pressure he emits at first, but is unruffled the rest of the fight.

Trivia

 * Donadrond, along with his name "Donnadorondo" in the web novel, is likely a mock of tough-guy veteran characters.
