Artist's commentary
In Search of a Bond
There were two magicians.
The quarrels between the two never ceased. Having different tastes, learning different spells, and unknowingly entering different armies, the two fought on the battlefield.
At the end of the conflict
in order to attain the title of a great Grand Witch, they sought the forbidden spell to control a person's soul.
By nature the forbidden spell should be unusable by humans, and because of the fierce recoil at the moment of activation,
the spell will not be complete unless someone stops that recoil.
Upon completely taking the recoil, however, the soul will be devoured and the body reduced to dust. In other words, the one to survive will be the victor.
Risking it even now, it can be nothing but their final match.
In the midst of the spell the two realized, at the same time as they fought each other out of the want to each obtain their own desires, that they had continued to encourage themselves from their partner's unseen shadow.
