Name: Sangre-serpiente
Release Phrase: Forunculo.
Represent: Black Mamba
Element: Poison
Sealed Description: A long katana that is totally black including the sheath. In all other aspects it is nondescript.
Initial Release: Ryou’s hair spikes up, individual locks of hair condensing into a mass of writhing snakes. Each snake has it’s own personality and will, including poisons. The snakes re-grow when cut, and can extend themselves. Her skin darkens to a black color and small yet strong scales coat her body. Her body seems to become thinner and more slender, while her eyes narrow and become slits. Pits appear under her jaw, and her tongue becomes forked. Her internal body structure morphs to include several more snakelike attributes including a Jacobson's organ. Fangs protrude from her mouth. Because of her new form, Ryou’s senses are more aligned with a snakes. Her eyes can sense heat signatures, she can feel vibrations both airborne or earthbound. Ryou’s tactile senses are increased to an unfound level.
The most profound change however is that her blood mutates into a toxic form. It is a continuously mutating poison, sometimes acid like or even sometimes gaseous in form. Because of this fact, Ryou cannot be poisoned by any other substance as her blood is continuously creating antibodies for any poison that enters her bloodstream. Her very reiatsu becomes poisoned, so that if someone was to ingest it or absorb it, they would be poisoned themselves. Her pores excrete poison as well, making physical contact rather dangerous.
While in this form her speed is increased exponentially, enough so that she could stand toe to toe with the lower ranked Espada. Her agility and precision are also increased to an incredibly level, bearing more resemblance to a black mamba. The scales that coat her skin are small and delicate looking, yet they are tough enough to stand up to shikai level attacks and even put a dent into others.
Released Description: Ryou will become even more slender. The snakes in her hair will grow more virulent and double in ferocity. The scales that coat her body turn a silverish white. Her fingernails will grow sharper, and poison sacs appear beneath the nails. Ryou's mouth will grow larger, her jaw thickening and morphing until she is easily able to unhinge it.
In this form Ryou can elongate her neck to incredibly lengths, striking even swifter than in her previous form. She can manipulate her body into all sorts of distorted forms, easily dislocating joints and other body parts with no injury to herself.
The very air Ryou exhales will hold trace amounts of whatever poisonous state her blood is in at that moment. In this form the poison within Ryou becomes extremely virulent, enough so that it could eat through the toughest of Hierro. Ryou can spew this poison into the air instead of having to bite someone to inject it, and once airborne she can direct the particles of poison. These particles can coalesce to form solid objects and such.
Her speed is increased further more, along with her scales growing thicker and more durable.
Ultimate Ability/Attack: Ryou can administer a poison that effects either spiritual energy or health. Once the victim is poisoned by this toxin, they will begin to lose Reiatsu or health which is then transferred to Ryou. This particular poison can also be used to drain reiatsu from incoming attacks, lessening the force somewhat. She can even use this to drain Reiyoku from someone. If the poison is in this form and she maintains the attack for 15 turns, the victims Reiyoku will be fully drained making it so that they can never regenerate it. (Like someone destroying the Saketsu chain and Hakusui chain only over a prolonged period of time.)
