Club Jyuuken y Kenshiro VS Ikkitousen y Extras

Shin has the power of the Dragon's Eye (龍眼 ryuu me or ryuugan?), which synchronizes with the spirits of all things,[2] thus it gives Shin a type of prescience that allowed him to 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, the other part was due to his father.
When Maya asks why he didn't just predict certain occurrences, Shin compares his power to rain. All the rain drops hit a predetermined place, based on wind and such. They congregate together to and flow, eventually making a stream; according to Shin that is fate.[3] He basically says he can hear the rain, but he can't understand the significance of every drop.[1] Basically indicating 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 has the power of the Dragon's Eye (龍眼 Ryūgan?), which synchronizes with the spirits of all things,[7] thus it gives Aya a type of prescience that allowed her to 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 motorcycle. 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. 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.
