In a world populated by fierce and hostile creatures, a hero is there to protect the widow and the orphan, this hero is Kolos! Tall, very-very muscular, Kolos has never known fear, not the time. His daily life is: slaying dragons, knocking out trolls, extinguishing volcanoes, stopping earthquakes and doing squats and pull-ups.

His life will be turned upside down the day his long-time enemy, the terrible sorcerer Zardos, opens a dimensional door and sends him to the world of Choukikitty. In this world everything is pink, perfumed, happy and too cute. In short, not really the kind of environment that our hero with a thousand muscles is familiar with.

Fortunately, he will meet Lisa, a resident of Chukikitty.

This adorable blue rabbit who spends most of her time bending over backwards to answer the complaints of her happy and peaceful village will take advantage of Kolos’ arrival to go on an adventure, to become emancipated and to try to find the trace of her missing parents.
