Mankind's existence is threatened by an enemy organism named "Dissolve". Why is it attacking the earth, and moreover Tokyo intensively? I don't know why. "Mido Kyosuke" and his childhood friend "Kaifu Cane Hikari" were in the so-called DAKT, a special organization under the United Nations against the Dissolve Interceptor Agency, which was formed to counter the "Dissolve".

And "Ryoto Sigismund", who belongs to "DAKT" like "Kyousuke Mido" and "Hikari Kaifutsune", belonged to DAKT's intelligence department because of his aptitude. He has established his position within DAKT by demonstrating his ability to deal with situations that cannot be dealt with by espionage, counterintelligence, organization security, and the Special Processing Self-Defense Force, as well as by the pilot of "Siegfried" alone. However, he had a "purpose" that was incompatible with the purpose of "DAKT".
