Union Magic: Sea God Slash 「合体魔法『海神降ろし』 Gattai Mahō "Wadatsumi Oroshi"」 is a song- and butoh-based Union Magic spell.


With open grimoires, Song Magic is used to enhance Butoh Magic, and the magics combine to create large magical auras around the dancer's swords. When the dancer swings their swords, powerful shockwaves and flying slashes are produced.[1]

This spell is also a form of worshiping the Seabed Temple's Sea God.[2]


  • This spell is a reference to kamioroshi 「神降ろし」, a Shinto ritual musical performance.
