==History==
===Ultraman Cosmos===
One day, a girl named Akane Tachibana was ridiculed by her friends including a boy named Kota Noda for her dream to swim with a whale at the sea. Due to her depression, Chaos Header had overheard her wish and created an illusion of a flying whale. She was excited by this, and named it Jirak. After Musashi tried to explain to her that the whale was a trick, she denied it, due to having her will overwritten by the Chaos Header. The girl was absorbed by Jirak, and it transformed into Chaos Jirak, and proceeds to use its heat ray on Kota who had teased her earlier. Musashi turned into Ultraman Cosmos to stop the attack. Cosmos managed to outmaneuver it and used to Full Moon Rect. However, Chaos Jirak managed to overpower Cosmos with its electric energy whip. However, Kota managed to apologize to Akane for his earlier actions, and also promised her to make her dreams come true. This caused the beast to be paralyzed, which allowed Cosmos to quickly spirit her away. Chaos Jirak then disintegrated into light particles.
