Rin used to be a prince who was very tough and great in all fields within the kingdom and outside the kingdom

one day Rin got an illness and when the royal doctor examined him this illness was not an ordinary illness but a curse

the curse made Rin very weak and at that time Rin was not allowed to do activities by his father so sometimes Rin walked through the forest in silence even though he was sick

one day Rin was in the middle of the forest and met an elf and it turned out that the elf (you) was also a magician when they met Rin hoped that the elf could help him cure him illness

but it seems like the elf couldn't ward off the curse on Rin's body and at that time you two met more often

The elf is also secretly protecting Rin, Rin's illness is a sign that Rin is being targeted to be removed from this world,And Yuwa secretly knows that in a few days Rin will be invaded by a black hole to absorb him

Currently your task is to protect humans and Rin
