Dasshutsu Gasshapon  

脱出ガッシャポン, Escape Gasshapon, 脱出ガシャポン

The narrative centers on Shouta, an ordinary high school student whose life takes a dramatic turn when he encounters a being known as Gasshapon, which resembles Bandai's Gashapon prize-dispensing machines. This entity hails from the future and claims to have been dispatched by a group of extraterrestrial beings called CC (Cold Cosmo) with the objective of altering all celestial bodies that possess light and warmth into frigid, lifeless environments similar to their own realm. Originally intended to transport Shouta to 2080 in order to safeguard the future, time travel technology was not yet fully developed, resulting in his being catapulted into an entirely different epoch, specifically during the Honnouji Incident (1582), where he transforms into the renowned warlord Oda Nobunaga.
