Clan: Fukuyakou.

Kekkei Genkai: Ghastly Sweep.

Elements: Earth (Doton).

Specialization: Ninjutsu.

Location: Kirigakure.

Clan History: The clan was born when two brothers tried to create the perfect stealth technique, called Ghastly Sweep. But the technique was quickly confused with some type of demon technique, as they could hide and only be detectable by sensor types (exorcists in that time). Decades later, they immigrated to Kirigakure after helping them with the development of the Hiding in Mist Technique, based on their own technique. During the Blood Mist, they were frequent targets of assassinations, kidnapping attempts and from the black market itself, as they could teach anybody about their technique since they could be useful for stealth purposes. But, their leader in that time, Fukuyakou Naraku, decided to protect his family by casting their signature technique on the genes of all the members, ending with all the struggle they had to face. In recent times, the clan revived and became stronger, claimed by a great number of organizations because of their natural ability to hide their presence.

Kekkei Genkai Description: Members of the Fukuyakou Clan learned how to hide their presence from others by discharging half of their chakra away, creating a technique called Ghastly Sweep, where nobody will even notice them around. But, even being considered a useful ability, sensor type ninjas can still detect them, regardless of where they are hiding.
Drawbacks:
- Sensorial techniques can detect them.
- They are unable to learn any form of Taijutsu.
- They must take Earth Release as their main element.
- Their Chakra Pool is reduced by 60% (150 > 90, for example).
- The Hiding Technique will deactivate automatically if the user shows bad intentions (rape, assassination, kidnapping, and backstabbing) towards another person.

Members: Fukuyakou Naraku (NPC, Dead).
