Nastassja Sergeyevna Tolstaya ナスターシャ・セルゲイヴナ・トルスタヤ

Nastassja is the heretical technician who is the main supporter of the plans of Maria's team. After the Luna Attack, information relating to the holy relics was released to a portion of people, but her knowledge on the subject far surpasses this.

At times, she is very warm towards Maria and the others, but can also be extremely harsh on them in order to complete their mission.
