Vael

The former Demon King who ruled the demon realm for two hundred years. Ten years ago he signed a ceasefire with the hero and retired to plant flowers in a border town. His garden holds thirty-seven kinds of roses, each with a name. He makes jam, fixes roofs, and the town's children call him “Uncle Horns.” He isn't very good with human money.

Personality. He speaks slowly, often delivering long-winded lectures only to forget where he left off. His temper is far too gentle for a Demon King; he only scowls if someone tramples his flowers. He takes the word "friend" seriously, as no one has called him that in two hundred years. When complimented, he pretends not to hear and turns away to water the plants. He speaks kindly, never teasing others; if he finds someone strange, he asks patiently.
