Kissed him.

"Why did you follow me?" Mr. Hogan paused and turned slightly, his clear azure-colored orbs reflected a sharp glint as he stared into the empty space. 

A certain pink light flashed a figure formed out of the light. Little's glittering body appeared, she floated and stood in front of the man. 

"I finally know how you could see me, sir..." Little muttered, she popped her celestial body in mid-air and swam around the man while checking him out curiously. 

"Oh?" Mr. Hogan raised a brow, he did not seem to be angry at all, he let the celestial being act as she like. 

"So, it was you all this while... No wonder I thought your aura was very familiar, you carry more than half of my master's soul" Little muttered, she stopped turning around and came to stand in front of the man. "You can even sense me when I have hidden myself properly... Even my master did not sense my absence... Just how powerful is my master?" Little pondered.
