The Song of Swans, Rabbits, and Cats is a Grand Spades that is also a Grand Sword. Even Christopher Sincere Pride could not utilize the most minuscule fraction of 0% of its power.

The potential of this Grand Sword is astronomically transcendentally boundless, to the extent that a Voyager personally appeared to handle the situation of it materializing.

The Song of Swans, Rabbits, and Cats is not to be wielded by the hand, but by transcending the Ascending Hierarchy of the Mind alone.

The Song of Swans, Rabbits, and Cats was introduced in Pharos of the End.

It is currently within the possession of The Silver Devil.
