Timeline

Mikkoku Damasu is born.

Mr. Damasu begins to teach Mikkoku (age 5) basic medical skills.

Mr. Damasu is recruited into the secretive, underground organization of scientists—dubbed 'Ivalyce'—in order to study the effects of Hol'locie on the fauna of the planet.

Mr. Damasu dies, leaving Mikkoku (age 14) alone in the world (although, at this point, she is more than capable of taking care of herself).
[He is one of the casualties of Xyncx's escape.]

Mikkoku seeks out the organization Ivalyce, offering to assist them in their research as a medic—and even as a test subject.

Mikkoku is held within Ivalyce's facilities as a permanent test subject, and they begin experimenting on her with Hol'locie and Xaerian DNA.

Mikkoku's DNA is altered by the Xaerian DNA, causing her to become frail and weak. Her body rejects the Xaerian time and time again.

Mikkoku Damasu's (age 15) body stops rejecting the Xaerian DNA, and it slowly begins intertwining with her own DNA.

Ivalyce continues to push Mikkoku's body to the extremes, forcing transformations on her that tax her body—yielding in abstract and bizarre mutations.

During these transformations, Mikkoku has a tendency to go feral/get violent. Ivalyce commissioned a local magic-user for a "bewitched ribbon", which restrained and calmed Mikkoku when in her enraged state.

The Xaerian DNA has finally settled within and intertwined with the entirety of Mikkoku Damasu's (age 17) body.

Mikkoku begins to notice that, with each injection she receives hereafter, her senses heighten and her physical limits/endurance increase. Mikkoku realizes that her body has finally accepted and become one with the Xaerian DNA, and that she is slowly becoming more powerful—and more dangerous.

The transformations Ivalyce force on Mikkoku are not nearly as painful as they used to be and result in mutations or failures less and less. Mikkoku is developing a "Xaerian forme" more and more each day.
Although not as painful, these transformations still result in excessive rips and tears in Mikkoku's body—which remain on her human form when she transforms back. She is once again fending for and patching herself up alone.
During the time her body begins to develop this "Xaerian forme," she begins to be able to overpower the bewitched ribbon Ivalyce used against her.

Mikkoku Damasu (age 18) is finally able to retain her Xaerian form with stability and transform at will.
She, however, notices that the Xaerian DNA has continued to make her skin and bones more brittle and weak—so she takes up the mantle as the head of Ivalyce using her newfound powers, knowledge, and Xaerian forme (along with a display of power over a tool once used to restrain her—the ribbon). She spearheads the Ivalyce initiative in order to harvest Xaerian DNA and Hol'locie in order to keep her human form young, refreshed, and strong.
