Jureve

Jureve (ユレーヴェ Yureeve) is a liquid made of certain magic materials. It is used to melt hardened mana in the body. Nobles always carry jureve with them when life-threatening emergencies occur. One must collect the materials themselves as the materials must be dyed by one's own mana to ensure the quality of the material. Normally nobles gather materials during their time at the Royal Academy.

Story
Rozemyne has to make jureve to melt away the mana clumps inside her body. As years have gone by since the clumps manifested, she needs materials of the highest quality. Those are gathered throughout the year in each season where the seasonal mana is the highest. If she fails to obtain one material, she has to wait a full year until she has the chance to gather it again.
