"There's no future in that direction..."
~ Mirei, Valkyrie Drive Mermaid


Mirei Shikishima is the protagonist of Valkyrie Drive Mermaid, and is Mamai's Liberator. She is a young girl who possesses an outstanding figure with tan skin and blond hair long enough to touch the ground. Due to her extremely reserved appearance, people think that she's a scary person but in reality, Mirei is a pure-hearted innocent person. Courageous and energetic, she doesn't avert her eyes from disturbing scenes. Still, she is fond of cute things. As a Liberator, her power is S-Class. Because of her reserved nature, only few people are aware of her past.

Mamori Tokonome is an obedient, sixteen-year-old high schooler, gentle, with a trait of speaking politely. Her chest is big, but her height and face resembles that of a middle schooler. Despite wishing to avoid conflict, she instinctively speaks up for the weak, wanting fair treatment even for those who have tried to hurt her. But when she met Mirei, her Liberator, she found she possessed the power to transform her body into a weapon. Her hobby is reading and she is worried being called by her surname "処女 (Shojo/Virgin)" (Half of it, she gave up).
