This card's effect which Special Summons it from the Graveyard to the opponent's field does not target.
This card's effect which discards one card from the opponent's hand when successfully Special Summoned does not target.
For the effect which discards 1 card from the hand, the person who selects a card and discards it is the opponent of the player who activated the effect.
If this card is Special Summoned to the opponent's field by its own effect, then its "when this card is Special Summoned" effect also activates. The effect activates separately, in a new Chain, after the first Chain finishes resolving.
