Toransugan

An ancient Kekkei Genkai, the Toransugan is a powerful eye forgotten by most of the shinobi world. This powerful eye was one revered by the world at one point of time. It's time of use only was before used during the Sage of Six Paths time of living.

It's current and only wielder is Izane, who is the last surviving member of the clan it belonged to.

Abilities
Like most Dojutsu, the first of the Toransugan's powers is being able to see chakra flow. The Toransugan itself gives colour to chakra, allowing the wielder to differentiate them. They are also able to tell if a person is under a genjutsu because the person's chakra flow would be irregular. The Toransugan's second-most prominent ability grants the user an incredible clarity of perception, allowing them to easily recognise genjutsu and different forms of chakra, though not to the same extent as the Byakugan.

It's most prized and most powerful ability is the mind-controlling genjutsu. This eye has the ability to put the target under a genjutsu making them do what the user commands. This ability rivals the Kotoamatsukami ability of the Mangekyō Sharingan. However unlike the powerful ability of the Mangekyō, it has time duration. This is the drawback of the eye. It only lasts for a total of One year and a half before the target it was used on, snaps out of the hypnosis.
