Nova sword

Nova Sword (ビッグバンライト, Biggubanraito, Bigbanglight) is a spell of the Light alignment in Magical Starsign. If the protagonist is aligned with Light Magic, he or she will learn this spell at Lv 52.

Front row
The caster summons a heavenly sword above the field. It releases a powerful light and strikes an enemy with four crescent-shaped slashes, then pierces it head-on to deal the finishing blow.

Back row
Much like the front row version, a divine sword is called forth, but four more are produced along with it. Each one launches a powerful maelstrom of slashes before striking all enemies in unison.

Name origin
Nova Sword is likely named after Nova the Light Planet. It may also refer to nova stars, which are stars stripped of their elements by a white dwarf.

Its Japanese name, Bigbanglight, refers to the theorized Big Bang event that is said to have created the universe. It is also is meant to follow the naming convention of the Light-aligned spells' Japanese names, all of which are named after space-related concepts (Starlight and Spacelight).
