My dear author of this big fanfic would like to give an idea about the ability that Kiyotaka can receive this is
Damn skill: Ghoul reincarancion:
Effect: You can summon the ones that you have killed as shows .Tus Death agents would not inherit the ability they had in life, however, if you want your death agents, they can inherit their physical forms and memories. They will only be summoned as you do not want their memories to retain how you can use it once a day.
