Killkill

Killkill (キルキル) is one of Minami's familiars and a character that has yet to make a formal debut in Deep-Sea Prisoner's creations. He first appeared in the Sunahama log on 2017/05/27. He is a box jellyfish.

Physical Description
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 six-pointed star emblem similar to Minami's symbol stitched into the hood.

Personality
Killkill is said to have a gloomy and introverted personality. Deep-Sea Prisoner has also stated that Killkill is a bit of a yandere.

Background
Not much is currently known about Killkill's past.

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

Minami
Minami is Killkill's master. The precise details of their relationship are currently unknown. Killkill addresses Minami as "Minami-kun."

In Deep-Sea Prisoner's Halloween 2020 livestream, she answered a Marshmallow question where she confirmed that Killkill "sexually harasses Minami," but that the latter is oblivious to this. It was not specified if this includes when he was a child, or as an adult. The phrasing points towards the latter.

It's also been said that they take naps together.

Trivia

 * His character portrait was drawn during Deep-Sea Prisoner's 19th drawing livestream on December 26, 2020.
 * 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 of his introduction and the way he called for Minami in the caption, it is possible that Killkill is attracted to Minami.
 * In Japanese culture, the six pointed star found in his design shares no history with the Star of David.
 * He may have appeared with Minami in animal form in the Sunahama 2017/05/28 (Note: The jellyfish may also actually be "Fuwa~n" Jellyfish given the length of the tentacles).
 * He appears in an image titled "Danger Sea," alongside other red-eyed glooming shadows. This may suggest that he will turn out to be an antagonist.
 * Deep-Sea Prisoner has stated that Killkill is male but has a loose sense of his own gender; it is not something he cares about a lot.

Quotes
