[spoiler=lore]This card can only be Normal Summoned by Tributing 2 DARK monsters from your side of the field. If this monster is Normal Summoned and destroyed by battle, it is sent to the Graveyard without applying Damage Calculation. When this monster is sent to the Graveyard as a result of battle, without applying Damage Calculation, it is Special Summoned to your opponent's side of the field, at the beginning of their next turn. When this monster is Special Summoned to your opponent's side of the field, by its own effect, it cannot be used as a Tribute. Your opponent must pay 500 Life Points and attack with this monster every turn. If not, destroy all monster's on your opponent's side of the field. If this monster is destroyed by 1 of your opponent's cards, when it is on their side of the field, inflict 1000 Points of damage to your Life Points. When this monster is on your opponent's side of the field, you must pay 1000 Life Points to attack this monster.[/spoiler]
