My SearchFu has failed me, master.
What happens when my Daigotsu (Experienced 3) uses his battle ability on an opponent's Houhou?
Daigotsu Exp. 3: Battle: Permanently give a target enemy personality with lower Chi Shadowlands. He succumbs to the Dark Lord's will. Take control of him (if you do so, he joins your army). If you now control him, destroy him after this battle ends.
Houhou: Limited: If Houhou is honorably dead: She rises from the ashes. Bring her into play, paying 4 less Gold. If she entered play, gain 3 Honor (this is an Honor gain for entering play).
After Houhou is destroyed does it go in my discard pile or the opponents?

Houhou goes to her owner's discard pile when she is destroyed.
Areas of the game, Discard piles (out of play): "If a card you own is about to enter another player’s discard pile, it enters your corresponding discard pile instead."
