Krinsa’s beginning is an obscurity. All that is known to Krinsa is that her mother, an angel, was held prisoner by a Demon that defiled and impregnated her. Somehow, she escaped back to Heaven where she gave birth to her child. It was then that they were disturbed by the growth of both types of genitals on the baby and exiled it to the world below, figuring she would die on her own. Of course, this would not happen.

As time went by, she was raised as a weapon by a group of scientists in the Machina of Man for her abilities as a descendent of both Angels and Demons. Of course, Krinsa only understood what the scientist told her for the first 16 year of her life as she underwent experimentation and training in a multitude of weapons, though she had more of an affinity for melee weapons. Perhaps something from a raging demonic heritage they assumed.

Over the next few years, the experiments and training continued and another “test subject” was brought in. This time, a full fledged angel that the scientist had somehow gotten their hands on. Locked in the same cells, the angel quickly felt the mix of blood in Krinsa and spoke up about it and telling her a story of a half-blood baby sent to the land of machines years ago. . .

The next day during her training section she got her hands on the newly created Arkshock Blade. They instructed her to cut the angel in half with it, wanting to test it on a live subject. Krinsa couldn’t bring herself to do it and instead used her uncontrolled power to escape the facility, grabbing a cache of weapons and leaving a trail of destruction in her wake.

With that, she escaped with the angel and the two returned to heaven with Krinsa attempting to do so with peaceful means. Of course, she was denied with the excuse of her blood being a blemish on her existence. She’d have no such luck getting in. . . Not that she didn't expect that. It is why she took the cache of weapons. There was little chance of getting back in to the Machina of Man so that left her one choice. . .
