The Flying Whale (飛ぶクジラ Tobu Kujira) is the sixteenth episode of Ultraman Cosmos.
Akane is upset when her friend Kōta teases her for wanting to swim with whales. Chaos Header materializes her whale dream into reality as Jirak, the flying whale. When the EYES team come to investigate, Akane merges with the whale to become Chaos Jirak. She fights with Ultraman Cosmos. Kōta shouts an apology, which she rejects. He then promises to leverage his fathers bakery business to pay for a trip to Dominica so she can swim with dolphins. With that, she relents and turns back into a girl.
