Rain_Thundercloud
Thanks for the chapter! Reincarnates her sister in one of the students, it seems so predictable, not that this is bad, but why not transform her into a magical being or even a magical weapon that will help Rain get stronger, after all she was able to call her own demon, I don't know if in this world it's common for magicians to make contracts with supernatural beings or if they have sentient magic weapons. I don't know if you would also agree to remove her memories, but let her have the impression that she has to stay with Rain at all costs and without understanding anything she decides to stay close to him to find out the cause of this feeling, and she turns into Yandere again.
