Zest

Zest is a Demon who originally served her creator, the Demon marquis Zolgear, as his aide. She was sent by the current Demon Lord faction to act as a scout alongside Lars to survey the conditions of Toujou Residence. After Zolgear's defeat, she temporarily served Maria's Mother, Shella as she lost her original purpose and merely compiled with the demand to join the Moderate Faction. She ultimately serves Basara as she was tied to Basara in the Master and Servant Contract through Shella's curse.
