Install & Exhaust (インストール&エグゾースト Insutōru ando Eguzōsuto)[1] is a unique attack possessed by Hayate Yagami in the portable continuity, making use of a force field. Notably, she has never cast nor been described as capable of such attack in the primary continuity.

It absorbs a nearby opponent into (the "capture space" of) the Tome of the Night Sky in a way similar to Absorption, and then ejects the opponent after exhausting his or her energy.

Notable usesEdit

It is Hayate's cross-range catch attack in The Battle of Aces and The Gears of Destiny, capable of blowing the opponent away to the long range.
