Demil Graha (デミル・グラハ, Demiru Guraha) is a legendary appraiser. People whose skills are recognized by him are considered first-class magic model makers.
He looks like an elderly gentleman wearing a monocle.
Demil holds magic models in high regard, easily becoming outraged when people make light of it. But he can become very easy going when they demonstrate proper skills, having a complete 180 transformation when Anos showed him his magic model, even though he was a little antagonistic towards him a few moments ago.
Demil visited the Magic Model Shop "Homeland of the Dragon of Creation" to inspect the phantom gem, a magic model said to be among the top 10, praising it and giving his expert opinion. However, he overhears Anos' thoughtless remarks and gets offended, but soon finds himself shocked when he creates a billionth scale magic model of Dilhaide. Demil tries convincing Anos of becoming a magic model maker, but Anos left with Misha as he wasn't interested in becoming one.
