The Dragon's Eye(龍眼, Ryuu no me or Ryuugan) is a power/technique from the manga and anime series Tenjou Tenge.
The Dragon's Eye is a power that synchronizes with the spirits of all things, thus it gives it user a type of prescience that allowed him/her to see anywhere past, present, possible futures, as well as seeing and hearing the dead. Dragon's Eye can also be used to make astral project and psychometry. The Dragon's Eye is known for its capacity to consume KI indefinitely, so sustaining it too long can cause the user to lose consciousness.
The only know users of the Dragon's Eye are:
Aya Natsume (棗亜夜, Natsume Aya) Her powers fully awakened around the time she entered high school, unlike her brother who awakened his power when he was still a boy. Although when younger she showed signs of her ability, since she was able to hear her dead parents voices when they were speaking to Shin. Aya can see anywhere past, present, possible futures, as well as seeing and hearing the dead. Aya can also use her Dragon's Eye to astral project and to use psychometry with Shin's motocycle.
Shin Natsume (棗 慎, Natsume Shin) Shin can see anywhere past, present, possible futures, as well as seeing and hearing the dead. He gained this power as a child, and it was far too much for him. As with all Dragon's Gate related powers, losing to your Dragon and becoming insane and violent is a huge risk. Shin lost leading to his erratic and violent behavior. His power played a key role in his insanity. His Dragon's Eye will only show him bits and pieces of possible futures, and he doesn't have the ability to piece together the whole picture. This makes the power worthless in his opinion.
Aya Natsume (棗亜夜, Natsume Aya) an ancestor of Aya,Shin and Maya.
Natsume Iyo can also use the eye of the dragon being one of the first users of the Dragon Natsume.
Iyo could see the future clearly and always had the eye of the dragon active.
