Elrich and his trusty service Pokemon who creates his prosthetic arm from her own cytoplasm, which is still attached to her by thin strands of the goop. Since Auxi is a psychic, she knows when and how Elrich wants to move the arm, their minds sort of mingling in places as a result. This makes Elrich able to more or less understand her, but only when they’re connected.

Auxi loves coffee, but is forbidden from it because the jitters really mess with the two’s coordination.
