Chronophantasma (The One Who Should Not Be Here)

Chronophantasma is a title for those who should not be at the specific timeline. They are not the observation targets (観測対象) for the system, and they will not receive Event Interference – effect of this extends to those who are heavily associated with that person. Chronophantasma must return to their original states, eventually. There is no way of avoiding it. The only known "the one who should not be here" was Celica Ayatsuki Mercury, who returned to her original state.
