Killkill (キルキル) is a character that has yet to appear in anything. It's implied in the Sunahama logs that he is one of Minami's familiars. He is a Jellyfish.


Killkill has paper white skin and his eyes are large and deep blue with swirls in them. His white hair goes past his hips and the longer strands appear to also be his tentacles. Another physical trait of note is his blue tongue. Killkill wears a light navy blue zip-up hoodie sweater that goes to his thighs with a white star emblem similar to Minami's symbol stitched into the hood.


Not much is known about him.


Not much is known about his past.


Up to this day, Killkill has only appeared in some of Deep-Sea Prisoner's illustrations.



Possibly his familiar, it is unknown what type of relationship they have other than Killkill mentioning him by in a suggestive manner and wearing the same star symbol as him on his hood.


  • He first appears in the Sunahama log on 2017/05/27 and a second time on 2017/10/28.
  • The term 'Danger' he is referred by in his first introduction in the Sunahama log on 2017/05/27 could be implying that he is dangerous in a sexual way. 'Dangerous,' in Japan, is sometimes used to refer to someone with sexual experience or a sexual situation.
  • Given the context of the picture and the way he called for Minami there is a high chance that Killkill is attracted to him.
  • He may have appeared with Minami in animal form in the Sunahama 2017/05/28 (Note: The jellyfish may actually be "Fuwa~n" Jellyfish given the length of the tentacles.)
