A beautiful boy with dull mint-colored hair and red eyes. Contrary to his pretty appearance, he has a cranky personality and is even a battle maniac. Rather than being husband material, he's more like the kind of comrade you'd take with you to war. He even once wrote a letter to his superior like this: To the Grand Master, I'll skip the formalities. I don't do that kind of thing. The reason for my leave is that I'm going monster hunting for fun. Whether you approve it or not, by the time you see this, I'll already be long gone. I'll skip the closing remarks. I know my limits well, so just trust me. - Roen He is often misunderstood as having dead eyes, but there is strictly a glint in his lower pupils. However, if he narrows his eyes even slightly, it becomes invisible. There are mentions of him skipping Varka's training without permission to go "monster hunting" (which he considers playing), and he is known for employing violent tactics. Furthermore, Varka, the strongest human in Mondstadt, has said that Roen's physical endurance is even greater than his own. He often corrects himself mid-sentence, such as calling a Ruin Guard a punching bag before retracting it, or while testing an opponent, looking at their partner and saying, "Hmm... seeing as (Partner) looks so stup— I mean, innocent, it doesn't seem like an act..." He is also very direct when he speaks.
