The adventurers would enter the final boss room, expecting to encounter some scary demon king, however they only encountered a small bunny on a throne.

Is this little one being responsible for everything?

Unsuspecting and trusting. The adventurers made fun of the little rabbit, a big mistake.

"Ha, this isn't even my final form~"


Exclaimed the rabbit, who had been interrupted previously. Suddenly his eyes light up and his body begins to expand, crushing and shattering his own throne under the weight of his growing buttocks and newly formed muscles.
