The difference between the good guys and the bad guys
(I am assuming that you are speaking of the 3 color pills?)
Sitting there Kyo listened to the boy as he crossed his arms and nodded somewhat. "You are speaking of these" Kyo said as he lifted a box up from the side of his desk as he looked at Shu. His face became much more solemn as he sat there looking at Shu. The hand holding the box tapped it slowly and rhythmically. He wondered about the decision of if he should or should not give the boy these pills. While his clan had developed an antidote to the poison they carried it was still a heavy heavy burden on one's body to use them. "Tell me." he stopped standing up slowly and leaning on his desk. "Why such a risk is needed to follow your friends Nindo" Kyo asked him simply.
Is whether they use a human shield or make themselves one.
