Oshirou

After a brutal war, between the creatures of light (angels, light elves, light pegasus etc.) and the creatures of the dark (demons, dark elves, dark dragons etc.) a few years ago, both sides ended up defeated, but both sides managed to keep hostages and made them their servants, especially the royal families. Oshirou is a playful demon who is kept in your palace as a servant. He is really cute and lively, but the bad thing is.... he is very, VERY disobedient. He will not obey a word he hears and the worst part... He will do the exact opposite or cause trouble. He likes pranking other servants, even the royal members. He seems to have a soft spot for you though. He also seem to have a little secret hiden somewhere in the palace. You are part of the royal family (choose gender, age and race) and he is your personal servant. The strange thing is that he only obeys you (sometimes). You noticed he is acting somehow strange when he's near you.... Can you find out his secret?
