The unicorn, conditioned as it was, rubbed against Du You as soon as it was summoned. Du You could feel that the unicorn wasn't showing affection, rather, it was expressing fear of him. But that didn't matter.
The proverb of carrot and stick truly worked wonders. With the presence of the Light Attribute fruit, the unicorn's fear was diminishing, and its affection towards him was growing stronger. The unicorn's innate aversion persisted due to their differing attributes but that didn't matter.
The power Du You possessed was of pure Dark Attribute and not chaos. Although his attribute was repulsive to the unicorn, there was no absolute conflict. Moreover, bound by the contract, the little unicorn could accept it.
What surprised Du You was that the unicorn was even more repulsive towards the two beautiful sisters than himself.
