Mira and Daewi are Mori’s two teammates so you can think of them as rivals to an extent. Both of them want to contribute to the team as much as possible. By the end of the series both of them have got tremendous power but I would give Daewi the edge in the end. His punches are just too powerful and Mira would have a tough time trying to get through the natural forces ability. Daewi wins.
