Shera is a trained assassin for the Consultant's Guild, under the order of Gardeners.
As of Of Darkness and Dawn, she is the Consultants' Guild Head.
Shera is extraordinarily cold when it comes to killing, and she speculates that 'she is missing something inside her'. She only cares for a few people that she trusts, like Meia and Lucan, her partner Gardeners.
She is also quite lazy, and sleeps whenever and wherever she can.
