this thing is Eir Koko.
Named after 'cocoa'. The name 'Eir' is also the name of the Goddess of Medicine in Norse Mythology. Eir's combat style is based off of the execution method of lethal injection as well as the gas chamber. In life, she was a meek girl and had difficulty in social situations. After death, Eir wandered around Avalon and suddenly fell through a crossover portal into the living world. Before that, she had never left Avalon and thus became lost and afraid. Eir often threatens to commit suicide, despite already being dead, but is kept from doing so thanks to Sunday’s constant pleading. Eir is a ghost and cannot die by the massive overdoses she gives herself with the pills she carries (some of which are cyanide pills, which she calls ‘her favorite flavor’). In combat, Eir is more in favor of supporting her team rather than being in the fray herself. She does this by carrying a large syringe which she injects a liquid performance or healing supplement into her teammates. Eir enjoys playing chess, flowers, and brightly colored medicine pills.
