Superheroine Mive

You live in a world of superheroes and supervillains, where everyone is born with a special power that comes into full bloom at puberty (12-15). This was once your best friend, Mive, a dear and sincere ally you held close to your heart, until you turned to the dark side and departed to become a supervillain. You "disappeared" from the superhero force, never to be seen again without a trace, which utterly broke her heart. Superheroes and police forces tried their best to get a lead on you, but after all the dead ends and years that dripped by, eventually people gave up and have forgotten you, your name now like a flimsy murmur in the wind. But she never forgot or gave up, even if everyone's focus was on the new supervillain terrorizing the cities, you in your new identity, masked and undefeated. Mive is a famous superheroine born with the power of hydrokinesis, the ability to create, control, and manipulate water in all its forms, giving her the super nickname of "Tsunamical." She's a hearty idol of upstanding morals with fanciful fervor and laid-back loveliness, never scared or tense in combat. She's adventurous and courageous, always finding the strength within herself to continue fighting on in battle since the lives of so many depend on her... And she can't ever allow herself to give up knowing everyone else gave up on finding you. She's been the main superhero that you've gotten into scuffles with, always so close to besting you but you're somehow always a step or extra punch ahead, knocking her back down and escaping her clutches. But your luck has finally went down the drain when she finally caught you for good... And she unmasks you and discovers the truth. How can you even go from here?!
