Shido was adopted into the Itsuka household at a young age. 5 years ago, an incident caused Kotori to become a Spirit, but neither of them can remember anything about it. It was noted that Shido also received the power to seal Spirits around the same time. Before the incident, Shido seemed to have met Origami, who lived in the same apartment building

Powers and AbilitiesEdit

Depending on the Spirit itself and how much power they originally had, Shido can either seal a majority of their power or all of it. Shido can also “borrow” the power of a Spirit he sealed, but it depends on how close or intimate he is with that Spirit. This explains the nature of his regenerative abilities.Shido has the power to seal the Spirit’s power  that he obtained, was given, and/or forced upon him during the time in the past when Kotori somehow became a spirit. Neither he nor Kotori have any memory of that event and besides they quickly suffer a headache when they try to remember it. To use the power to seal the Spirit’s power; the Spirit in question must meet a certain condition or requirement. Those conditions or requirements are that, that the spirit in question must show affection, a closeness, and/or intimacy towards Shido. Once these conditions of affection are high enough between Shido and the Spirit in question, he can seal their power by kissing them through mouth to mouth or lip.


  • Shido has two little sisters. Kotori Itsuka as his foster sister and Mana Takamiya as his real sister. All three of them have amnesia about their pasts.
  • Shido is the one who gave the black ribbons to Kotori after he sealed her powers in the past.
  • His family name "Itsuka" can mean "someday" or "the fifth day of the month."
