Overview
Dokutsuki (どくつき) (lit. roughly, with poison) is the main character of Broken Bottles. Not much is known about her other than she refuses to leave her basement and she lives on the bottom floor of a dingy apartment. She also has insomnia and uses her chemistry set to induce sleep, possible using drugs or other things that affect her dreams/personality. It has not been officially stated, but her birthday is assumed to be the same as when Broken Bottles first came out.
Appearance
Dokutsuki has cyan-blue hair with what appear to be red shards of glass tangled in it, but Doodle herself has said that they are entirely up to interpretation. Some people draw Dokutuki with various objects in her hair such as Doritos (chips), puzzle pieces, air fresheners, etc., but most people just draw them as glass shards.
She has a dark orange short-sleeved shirt with a dark green long sleeve shirt underneath, and a red and black checkered skirt with suspenders. Her eyes are a light green-blue.
Personality
Dokutsuki is considered to be rather calm, and maybe a bit of a troublemaker due to killing NPCs in her dream world. It is possible she finds enjoyment in harming others or has a fascination for horror due to the somewhat dark and dingy dreams she has. In The Static Box event, she is seeing grinning and crying at the box. She is considered to be heavily reliant on her bottles in some depictions on fanart, and due the the presence of bottle and glass imagery spread throughout the game.
Past
It is possible that Dokutsuki has lost her memory as a side effect from chemical use, since an NPC comments about Dokutsuki "still not remembering him". Other NPCs interact more with Dokutsuki than NPCs with their protagonists in most other games; it is possible that they are parts of her memory that have taken the form of people. Not much is known about her childhood, but it is assumed that she has had some trouble with a pinked haired NPC that shows up in the Little Girl event and in other various places throughout the game.
