Oktavia von Seckendorff

Oktavia von Seckendorff is the witch form of Sayaka Miki.

Overview
The mermaid witch; it is in her nature to fall in love. Looking for the feeling that moved her so long ago, she moves with the entire concert hall. Her fortune only turns under the weight of memories and no longer moves toward the future. Nothing will reach her any longer. She will come to know nothing more. She simply allows no one to disturb her minions' playing.

Timeline III
The mermaid witch. Her nature is to fall in love. The witch continues to dream of a guitar resounding in the middle of a concert hall, a deeply moving impression from past days. Repeating within that time with little but sure differences, her wheels of fate move around calmly.

Rebellion Story
The Mermaid Witch. Once dreamt of love. This witch was cut loose once again from a part of the Law of Cycles. Unlike the Dessert Witch, the human and witch's body can act independently. She can appear anywhere as long as there is water.

Kyouko's Spear
The Mermaid Witch. Once dreamt of love. The Law of the Cycle split off some of its souls and sent them to the earth. One of them took the form of Dessert. Another took on the form of a mermaid. And the Law of Cycles itself descended upon the surface, more reverently than the morning dew. Her form was like that of a magical girl who once was.

Holger (Main Timeline)
The mermaid witch's minion, whose duty is to perform. Several of them form a hollow orchestra that continually plays music for the witch. People who listen to their music for long enough will lose their soul. This orchestra only exists for its witch; to her, the orchestra is everything.

Klarissa (Timeline III)
The mermaid witch's minion, whose duty is a backup dancer. She only exists to dance cheerfully behind the witch. Klarissa's appearance is oddly similar to Hitomi.

Anthony (rental ver.)
Servants of the Rose Garden Witch (rental ver.). They take the role of gardeners. As they are relatively docile and numerous, as far as familiars go, the Rose Garden Witch dispatched them as the main combat force for saving Homura. As they are under the direct command of the Mermaid Witch, the influence of her magic has changed their appearances. The medals on their chests are a treasure added by the Rose Garden Witch.
