"Stella~!" I let out a voice of surprise as I look at Stella who is now in a different form compared to her normal form. She's standing at about my height or maybe a little taller with extremely large horns on her head. Her skin is also deep brown right now and looks coarse just like her father's own. While her horns are constantly changing colors.  

Hearing my voice, she turns around and looks at me in shock while her body begins to morph again and changes into her normal petite figure.

After changing, Stella looks at me with a very embarrassed expression upon seeing my surprised gaze.

"M-Master, I am sorry for showing you that form. Every morning, my body always transforms into a full draugh for a few minutes before reverting back to my original form." Stella explains with her gaze still lowered. 

Phew.... that fucking surprised me. I wasn't expecting that.
