"It's not Shojo (Virgin), it's Tokonome!"
- —Mamori, Valkyrie Drive Mermaid
Mamori Tokonome is the protagonist of the series. she is a good-natured, 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).
- Can turn into a double ended spear due to the Valkyrie Effect
- Can combine with Mirei Shikishima to activate the Valkyrie Drive
She appears to have a red hair which is almost always tied in braids. She has a cat clip clipped at the left-hand side of her bangs. She has brownish hazel eyes and a short figure.
She wears the standard uniform that Veste has for girls with a pink bow tied at her collar. She wears thigh high white stockings and pink shoes.
She is not naturally yuri, and is originally embarrased by Mirei's stimulating her into Drive. But she has an instinctive trust for her Liberator, even before understanding what is happening to her.
Although she lacks the physical strength and endurance that Mirei has, Mamori makes up for in bravery and selflessness. She will speak up against what she believes in wrong and and will engage in action if need be. In Episode 3, Mirei was willing to take the blame for the theft. However, Mamori ran to her aid and initiated her weapon transformation instead of Mirei triggering it. In Episode 5, Mamori transformed just for the sake of cutting fabric for Nimi's clothes due to the latter's enlargement. Also, to keep Mirei and Kasumi from fighting any longer (as Mirei would suffer future repercussions and Hibiki was used for ransom), Mamori ran up to the balcony where Adel was and pushed Ange. This caused both Hibiki and herself to fall off the balcony. Although Ange was able to grab hold of Mamori, Hibiki was able to reunite with Kasumi.
This shows that Mamori would put herself in danger for the sake of someone else, even if she never formally met them.
After Episode 8 where Mirei enchanced her abilities, Mamori didn't question her out of respect for her privacy.
She can be a little sensitive about her family name. Because "Tokonome" can be read as "Virgin," Mamori was often teased about her virginity and innocence.
- Her family name "処女 (Tokonome)" can be read as "処女 (Shojo)" which means "virgin".
