The kid was impressed that Rifindio's mutated bloodline and the Celestial Laws of Blood on his Fangs managed to steal the mark without killing its hosts. However, what impressed him the most was the fact that Futsuka didn't notice his mark was stolen. Why? He was the reason behind it.
'I didn't want to give anyone any advantage, even the chosen ones. I made it so even they couldn't feel the presence of the marks from each other... Unfortunately, that also meant they couldn't feel their own marks anymore. Those guys noticed that and used Rifindio's special ability to the fullest. Quite smart.'
Indeed, that was the plan Roan came up with the moment he heard the kid mentioning the Chosen ones couldn't feel each other as well. There was a huge advantage to that strategy. Because they wouldn't really kill the other chosen, no one would think they obtained any marks. After all, everyone believed they had to kill the other party.
