kamishiro seren
An original character by Rakurakutei Ramen.
Distinguishable by her brown hair, headwear that resembles rabbit ears, and is usually seen wearing a jean miniskirt with black thighhighs and a long sleeved shirt.
Owner of the shop Karindou and a magician, she's roughly a millennium in age. She also has a knack for keeping and creating (generally odd) things inside a store room which exists in some other limitless dimension.
She is usually lazy and feckless, and only occasionally shows her serious side when the people she cares about are under threat. She was once known and feared as a godslayer, but has been hiding for so long nobody really remembers her anymore, and she'd rather just do nothing but relax for all eternity.
Her headband is actually a magic dampener made of angel wing that restricts her huge magic potential so that she can cast basic utility spells, rather than only destructive ones. She prefers using her magic for her own convenience, and often uses it on silly and/or stupid things, like using dimensional magic to transform pudding into swimming pool size.
Her mentor and "mother" is Elza Straherz. Their relationship is complicated by Elza's perversion, but she is nevertheless respectful of Elza's knowledge. At times, she actually reverts to a more childish personality in the face of Elza on the rare occasions Elza actually starts acting the mother.
She is "mother" to Tamaryu as well as Kinka and Ginka, herself. In truth, Seren is immortal and was exiled in the first place because she slew Tamaryu's previous incarnation, used Tamaryu's body as magical ingredients for a potion to grant herself immortality, only to wind up caring for Tamaryu's new form.
Like Elza, her physical form is actually of her own choosing - she actually has a more busty true form, but chooses a more sporty form willfully, and has breast envy simply because "it's more fun to long for things you don't have".
When she temporarily was in her child form, she had to use a cat ear headband, and was in danger from the pedophillic advances of Tatsuta Rindou.
