Gonna say no on the killer, I believe the professor said they succeeded or partially did, and I DONT KNOW (╯°Д °)╯╧╧ i think they either both died and we're together on the end? Or survived due to null and him having to complete the third wish. With there was an epilogue but ┗( T﹏T )┛they seemed happy in the end
Did they capture the killer? Did they ever develop the cure for Ein's parents lung disease? What is happening!? T_T
