Asobi ni Iku yo! EP1 - The Cat Who Fell to Earth

The episode starts with three members of different factions listening to a special newscast about an alien message, the first part of which has been translated to mean "coming to play". One of the members is then called to battle aboard an enemy ship. She successfully infiltrates the ship and disarms the Captain. The situation is disrupted by a UFO passing too close to both ships. When the same member comes to, the enemy captain detonates the ship. Later, during a memorial service for one of his ancestors, Kio Kakuzu finds a cat-like alien sitting at the buffet table.
