Eating Guillotine

Eating Guillotine (ギロチンを食べ, Girochin o Tabe) is a Spell derived from Reaper Magic.

Description
With this spell, the user is able to cast their own skull toward an opponent, with no detrimental effects, in order to attack. When the skull is thrown, it starts to set ablaze and begins to grows to an immense size, easily dwarfing any opponent that it has been used on. As the spell readies itself, the bottom jaw lowers and the mouth captures the target inside, burning them in the process. Once the target has been captured, the skull immediately condenses itself back to its original size, before exploding. This spell is extremely tricky since if the opponent tries to force their way out of the skull using pure strength, then the skull will expand much like rubber in order to compensate. Oddly enough, the user of this spell feels no pain from any part of this magic.
