Marine Cathedrale is the name of the treasured violin owned by celebrated musician Michiru Kaiou, an instrument she plays for concerts and, in some versions, turns into a weapon as Sailor Neptune.
Marine Cathedrale is Michiru Kaiou's violin. A renowned performer, she plays it frequently across the manga, the 90s anime, Crystal, and the Sera Myu musicals. This entry concerns the instrument rather than the anime building of a similar name where the Senshi once battled Eudial.
The violin is prized for its worth as much as its sound. During the Fantastic International Music Festival, a listener remarks that it is a five hundred million yen Stradivarius named for the temple of the sea. In both the manga and Crystal, its music first reaches Usagi as she slips into Mugen Academy and follows the melody to where Michiru is playing, and the 90s anime stages a comparable scene of Usagi happening upon the graceful genius mid-performance.
As Sailor Neptune, Michiru can also carry the violin into combat. She lets loose an unnamed sound-based strike in Act 30, and in the manga and Crystal she draws two titled attacks from it: Submarine Violon Tide and Galactica Violon Tide.
Michiru Kaiou, in both her civilian and Sailor Neptune roles, is the instrument's owner. A Stradivarius is a genuine centuries-old type of instrument built by a real family and treasured by collectors for its craftsmanship, so her ownership of one underscores just how wealthy she is.
Marine Cathedrale, Michiru Kaiou's violin, first appears in the anime episode Usagi's Idol: The Graceful Genius Michiru, when Usagi follows its melody to find Michiru performing.
