Demonic Illusion: Four Corner Sealing

This is a powerful genjutsu that Aichi Goron created to overcome the weakness in her Sharingan. This allows her to copy almost any elemental technique, genjutsu, or taijutsu she wants to. After encountering a certain jutsu and weaving the needed hand signals, the user places themselves and their target under a illusion that they are replaying the last events of their fight. The target's body is slowed down severely, allowing the user to memorize the hand signs, chakra level,and/or actions needed for the technique. After the technique can been viewed and memorized, the user seals it into their eye, and then further into their memory banks for quick access. All the while, less than a second has passed. Both the user and the target are relieved from the genjutsu and the battle continues. The user can review an entire battle from this technique to learn many jutsu and make adjustments to their fighting skills.

Aichi's version of this technique is different and is based on where the name comes from. Due to her DNA being semi-corrupted from Uchiha DNA, she cannot learn Lightning Release techniques from this genjutsu. This technique also drains a great amount of chakra from her, forcing her to use it only once on a target at a time.
