Fallen Angel Gate

Spatial Magic: Fallen Angel Gate (空間魔法『堕天使の抜け穴』) is a Spatial Magic spell.

Description
With an open grimoire, the user opens their hand as if opening a hole at the direction where the gate should be opened. At that moment, a hole appears and creates a similar hole at the desired location. The user can only create portals to places they have visited beforehand or can actively see.

Anything passing through the portal keep its momentum. The portals could also be used to redirect incoming spells back at the caster.

The amount of magic required for a portal depends on the size of the opening, the distance covered, and the duration. As such, a series of shorter jumps is less strenuous for travel over great distances but sacrifices speed in covering said distance. Portals are also more difficult to open in areas with dense concentrations of mana.

Trivia

 * Asta and his swords are able to pass through Firnal's portals because Asta unconsciously turns off the Anti Magic when passing through them.
