The Chronophantasma (居ない筈の者,Kuronofantazuma, The One Who Should Not Be Here) is a title for those who should not be in the specific timeline. They are not the observation targets (観測対象,kansoku taishō) 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.[1] The only known “the one who should not be here” was Celica Ayatsuki Mercury, who returned to her original state.
