Seemingly shy and distant at first, Mika eventually warms up to the people he knows. To those unfamiliar to him, especially those with high rankings, Mika prefers to observe them and understand their personalities before properly interacting with them as a sign of respect. He does seem to rely on other people for decisions, such as when to talk or what to say. Mika enjoys mapping, having joined the Knights of Favonius simply so that he could map all of Teyvat.
