- Name: Crimson Reflection Technique
- Type: A-rank, Supplementary
- Users: Kyashi Urami
This technique is one of the most powerful Genjutsu in existence. When executed, it traps the opponent in an illusionary word, usually a memory in the past. It forces the opponent to "experience" their greatest fears, making them relive a traumatic event over and over, or torturing them by physical pain. Similar to Tsukuyomi, the technique will cause psychological trauma, rendering the opponent disabled, or cause a complete mental breakdown. In rare cases, the trauma would be enough to destroy the victim's mind, killing them.
