In the Colosseum, Tsubaki was led into a trap where she was forced to fight against Noel Vermillion, Makoto Nanaya and Jin Kisaragi. After battling against both Makoto and Noel, Tsubaki sought true strength from her weapon, becoming Izayoi. She was conflicted between the Mind Eater and her own thoughts and love for her friends. Izayoi battled Jin, winning but believing she had killed him, being enough for Mind Eater to be lifted.
