E-eight

E-eight is the summonoid version of Aveline.

Story
E-eight was made the same day as Aveline. S/he became friends with the Number Summonoids and went along with them shortly after they were made, and stayed with them.

E-eight is captured by the Donutbot, but is later freed by Yunita, who isn't seen afterwards.

Trivia
E-eight is the only summonoid to be referred to as s/he instead of he or she in Summonoid. The same applies to Aveline, who E-eight was modeled after.
