½ Prince - Volume 2 Chapter 7

What happens when a scientist from a futuristic world reincarnates in a World of Magic and Knights? An awesome MC is what happens!

Who needs that… Hmmm… that guy seems too powerful for me to take on now… I better keep a low profile for now. You want me to help you? Sure… but what benefit can I get out of it? Nothing? Bye. Hmmm… that guy looks like he might cause me problems in the future. Should I let him off for now and let him grow into someone that can threaten me….. Nahhh. *kill*-

Yet strength is only a tool for Leylin, like any other. His goal, in the end, is his own.
