(M/n) is the son of Koro-sensei he has the same speed and ability like his father though he is not as smart as him unlike his dad he is human to say but he can live forever when he mates his mate lives forever as well even though he is human he is a alpha it is apart of the race his mom is from koro-sensei but he never met her. After his mother died when she gave birth to him koro-sensei raised him so pretty much he has lived a pretty crazy life what if one day the moon was turn into a permanent crescent by his father and later on he has to avoid dying as well even though he has nothing to do with it but what happens if one day (M/n) meets karma the soon to be the live of his life. I am not sure myself read their story together in life and find out. (Karma x male reader story.) Warning: Yoai aka boy love aka gay, has mature scenes, blood, death, later on angst ⚠️ (if you do not like this kind of stuff click off it and don't read it if you are still here enjoy!)
