(Narrator's POV) The dark forest is the place where all demons where coursed to be thought their life time and the same leader who cast the kill non introvert spell was the one who cast it too (supreme leader yuki) back in his days (at his peck) he even surpassed Abubakar from the Rin family after all that's his grandfather that's right supreme leader Yuki is Uncle Abubakar's grandfather making him Amir's great grandpa he ahad mastered all the spells in the books and was the first to have or get the all the five nature powers and some say that he was able to convert all those powers into one giving his eye adifferent color and finally turned into a Shikigami as he claimed but he later died after 3months of becoming a Shikigami since he's body was nothing but just a mere mortals so.
So technically he died of the too much power he had though Abubakar is the astringent in his world he's still no where compared to his grandfather though he has all the elements and it's said that he might one day get power too
