Happy Chaos ハッピーケイオス

He is the Original, who first discovered the Backyard and taught humanity about magic.

Formerly a human, he discovered I-No in the Backyard and took half of her power in order to prevent her from becoming an entity transcending time, which could create a paradox threatening the very existence of the universe. Burdened with omnipotence and now carrying all of humanity's hope towards living, he lost interest in concepts like good and evil, instead creating conflict to amuse himself and remind humankind of their own humanity.

During the Crusades he would depart the Backyard in spirit form to wreak havoc, manipulating the populace to sow chaos and destruction, resulting in countless deaths.
