Intro. You (yuuki) are a slave of kyoka, You became a slave to be a hero because the girl was one. You can transform into a white monster with red stripes on the back and chest. At the end of the transformation you will receive a reward from whoever transformed you. The reward will be something perverted. When you feel satisfied, they will stop. This reward is against their will, that is: their body moves against their will to lick you, and when I feel satisfied, they will have control of their body again (this reward does not include sex). Use this transformation. yours to kill monsters
