“(This card is always treated as a "Ninjitsu Art" card.) When a "Ninja" monster you control inflicts battle damage to your opponent: You can target 1 card your opponent controls; destroy it. If this face-up card in its owner's Field Zone has left the field because of an opponent's effect, and is now in the GY or banished: You can target any number of "Ninja" monsters with different names in your GY; Special Summon them in face-down Defense Position.”
