Both of them are caring older sister characters that have magic powers which cause them to take on a unique appearance (Djinn equip/Take Over magic) based on more mythical beings. They also hold high ranks in their respective groups, Hakuei is in the Ren royal family while Mira is an S-class mage. Both of them have also been affiliated with kind of dark backgrounds, Mira was slandered for her Take Over magic and the Ren family had ties with the organization Al Thamen.

The only other connection I have is minor, and it's that they've both been captured in different ways. Mira by the guild Tartaros and Hakuei being taken captive by an important character in Magi.
