Sacred Heart (セイクリッド・ハート, Seikuriddo Hāto) is Vivio Takamachi's Device that she receives in the Magical Girl Lyrical Nanoha ViVid manga.


Judging by Nanoha's reaction, Vivio named her device after Nanoha's own Raising Heart.

Vivio additionally gives Sacred Heart a "mascot name", which she uses most of the time: Chris.


Sacred Heart appears as a plush bunny that floats in the air to follow Vivio, with appearance similar to the plush bunny that Nanoha gave to Vivio in StrikerS. The bunny is actually an overcoat, its substance is an ordinary crystal like other devices.

It does not change its form when it is activated (its trigger is "Sacred Heart! Set up!") but grants Vivio stronger magical power and control, and could let her maintain the Adult Mode. Vivio in her distinctive Barrier Jacket thereon looks the same as her previous Saint King mode, which shocked Fate at the first time.

Contact Mode can also be known as an alternative form of Sacred Heart, as Adult Mode and it are mutually exclusive. Sacred Heart will be absorbed into Vivio's body. The trigger is "Sacred Heart Contact Mode, set up."[2]
