Became a Failed Experimental Subject

The reason I got the name Black Cat is because I often take the form of a black feline-type monster.

The only reason I take this form is because it's convenient for running away.

My body—an aberration that swallows abilities—has to take on a monster’s form in order to use that monster’s powers.

Other abilities can be brought out as needed, but things like silencing my movements, jumping, and landing without a sound—those require the physical structure of a feline-type beast.

When I use Fluid Swimming to hide underground, Yu Anna chases after the monster’s aura with her unique sense, slicing through the darkness like she's raking it with her hands.

Also, since Fluid Swimming shifts what it touches into a liquid-like state, making it intangible, there’s resistance—it doesn’t let me sink quickly.

That drawback can be solved with my darkness-sinking ability, where I vanish by submerging into my own shadow, so I’ve had to keep the form of a monster with lots of tendrils too.

Because of all that, I’ve always kept the shape of a many-tailed black leopard, though I discard wings or horns depending on the need.

There’s no better monster form for escaping—so it’s unavoidable.

Everything is to safely get away after killing a monster on the scene.

To turn back into a human, I have to disappear completely from Yu Anna’s senses.

But now, I don’t really need to do that anymore.
