Murrenreue

Murrenreue (ムレンロイエ, Murenroie) is an archduke candidate from Immerdink and currently studies at the Royal Academy.

Despite often complaining about how Ehrenfest was at fault for Immerdink's fall in the rankings and lamenting how nobody talks about how hard they have it, Murrenreue quite brazenly asks Lady Rozemyne to join the joint research project Ehrenfest has with Dunkelfelger, during a tea party Ehenfest has with lower ranking duchies. To everyone's surprise, Rozemyne is actually supportive of this idea, though naturally since it is a joint project, Dunkelfelger needs to give their permission as well.

As a result, many duchies are allowed to participate in a Dedication Ritual held at the Royal Academy, but Dunkelfelger makes it a hard requirement that any participating duchy needs to first play them in treasure-stealing ditter. Due to losing so many of their apprentice knights to the ternisbefallen unleashed by the rebels in last year's attack on the royal family, during the award ceremony, they feel unable to meet this requirement and forego participation in the Dedication Ritual, despite being the ones to spark the participation of other duchies in it.
