Jacket Purge (ジャケットパージ Jaketto Pāji) is a defensive function of a mage's Barrier Jacket, with which the caster takes the initiative to "unravels" in a second all the mana used to comprise his/her Barrier Jacket to cause a blast.
Jacket Purge is only the name used on the Japanese Nanoha wiki, presumably shortened from the notable command phrase in A's (ep.10), i.e. "Barrier Jacket, purge!"
- Jacket Purge is first seen in A's (ep.10), using by Fate Testarossa against the tentacles of the Scarlet Dragon. She simultaneously sets up (collectively form-changes to) Sonic Form and brings Nanoha Takamachi away from those tentacles.
- In ViVid (ch.97), together with the mana from her collapsing three-layer defenses, Vivio Takamachi purges her Barrier Jacket to create a blast, and takes advantage of its shock to break away from Nanoha's Blaster 2 Starlight Breaker, as explained by Teana Lanster and flashed back in ViVid (ch.98).
Reactor Purge is the passive and reactive version of Jacket Purge for last-resort defense.
