Love of Thirst - Sexual Desire

The Love of Thirst - Sexual Desire (渇愛・性欲, Katsuai: Seiyoku) is one of the original techniques that has been developed by Usetsu in correspondence to his acquisition of the Rinnegan. It is a derivative of the Preta Path, as well as its derivative Love of Thirst.

Description
As explained before, the Love of Thirst technique is one that embodies the underlying instincts of Usetsu as a practitioner of the Rinnegan - hunger and thirst. Those very things embodied the majority of his life, and do so up until this day. However, there are several forms of this simple instinctual craving, and the Sexual Desire technique is one of them. While the technique's name would indicate otherwise, this specific technique's effects revolve around the holistic feeling of pleasure and joy, birthed from the acquisition of immaterial things.

The functionality behind the technique, once again, is relevant to the Yin–Yang Release components of the Rinnegan. Utilizing a similar method to the Blocking Technique Absorption Seal, the user begins to absorb the chakra from any Ninjutsu utilized against it, thereby nullifying it. However, rather than absorbing the energy in itself, the Rinnegan provides life to this energy, giving it a material essence once entering the body. Therefore, the Sexual Desire technique can provide legitimate sustenance to the user in replacement of food and water.

Drawbacks
Of course, the process is slightly time consuming, and the user is left open if they aren't able to complete the process in time. It is also more difficult to do so with raw chakra than elemental chakra, for it is easier to provide "organic" life to chakra of elemental natures, rather than the pure energy form which raw chakra is normally in. As well as this, the absorbed material essence is not exactly sufficient for long-term sustenance, and is mainly utilized as a short-term method of boosting the user's energy - such as directing it towards the body's natural healing process.
