Barrier Break (バリアブレイク Baria Bureiku) is a Midchildan decline-type supportive spell to invalidate the defensive film of barrier-type spells. The Modern Belkan version shares the same name when developed.

In the early series, it is primarily cast by Alph to break barriers with her claws, fingers or knuckles. She seems to be very good with this spell as she is able to break the barriers of Presea Testarossa and Vita.

In StrikerS, Subaru Nakajima also uses this spell effectively with her Revolver Knuckle in close combats. She generally breaks a barrier by forcing her fingers (in Revolver Knuckle) through it and then clenching them into a fist.

Notable usesEdit


Barrier Break Strike is an offensive variation further developed upon Barrier Break.
