M01 - Destroy everything, connect everything
Affiliation: Daishocker(formely), None
This is not a conventional princess story, even though, Maruko could be considered as such. She was the offspring of the Great Leader of Daishocker, alongside her bother, Tsukasa. Both of them were raised to be the next leader and were in constant war. Their own existence was made in a way they could be matching all riders and all kaijins in fighting. They were supposed to be strong enough to rule over them all.
They were taught to hate and to belittle others. To consider themselves invencible. To accept the treatment as superiors(something that was carried on later). The battle between them grew to the point where they faced each other. The dimension wasn't ready for such powers colliding and a big explosion happened, resulting in a dimensional slit. Separating them towards two different sides: Tsukasa was in the neutral dimension. The positive dimension is the normal Rider world, where people like Godai, Kenzaki and Tendou live. The neutral Dimension is an alternative incarnation of the main world and home to Onodera, Kendate and Ogami. The Negative dimension(not to be confused with Nega no Sekai) is home to female versions of the original Riders such as Yuuki, Wakana and Shizuka.
Maruko was in a near-death state when she was found by her father's soldiers. They took her to Nega no Sekai and buried her there. The expected effect happened: she was healed from her injuries. However, when they came to pick her up and take her back, she already have gone, taking with her only her Decadriver, her Ridebooker and a pink tape recorder/sampler. She wasn't sure at first why she had that, but soon, her taste for music became clear. In fact, this was one of the first memories of her past: her wish to create a perfect rhythm.
It was because of such taste that she met Hikari Natsuo, a boy who worked on a Record Store and whose grandmother had been a musician during her early days. They formed a connection and for months, Maruko was invited to sleep on their home, to keep them company. She and Natsuo became remarkably close and he was her main companion during her travelling to other worlds. As Tsukasa could travel the worlds by the different wallpapers on the Photo studio, Maruko used an old jukebox that played music - or random sounds - of the chosen world.
Hikari Natsuo was killed during the event with the Perfecter when it played in her reality. This left her with great grief and made her scared to get involved with people romantically speaking.
She has all Decade powers and will have a proper counterattack for riders and Kaijins until W. After that she only will be able to do it, after a fight(which I, as a mun, am going to avoid because I’m a lazy bun).
Often asks to record people’s voices to use them in her remixes.
