A giant story featuring Gasper from the High School DXD series. After being teased about cross dressing Gasper is ordered to relieve his stress by terrorizing tiny cities full of people who could do nothing to oppose his whims. Don't like cross-dressing giants then don't read, but if you like my style and are even a bit interested then give it a shot, you might be surprised about how you feel about it.  

An adaptation of the game by Ochiko Terada (寺田落子) titled "Princess Calamity RPG" (姫様お散歩ゲー). 

Synopsis: The young Princess some way or another discovers magic that enables her to grow. Initially she uses her newfound powers to wreak havoc inside of her kingdom, but holding still an attachment to her own people, she decides to kindly spare them from total annihilation. Instead, the Princess sets her eyes towards their neighbouring continent just barely visible beyond the vast ocean. Her young heart has never borne any good will towards them and as such their land would serve as the perfect playground for her, she reasons. Before she leaves to cross the ocean, she grows even larger. The story begins with the giga-sized Princess approaching the coastline, an eager glee in her eyes.
