Convincing Styx

After the Beast Hunt incident, the Royal Family, particularly the Crown Princess, was agitated. With Savagery's untimely death, Deception likely put enormous pressure on her. As for Ruin, he was likely getting more serious in searching for the person the Crown Princess had asked him to find.

Kyran and True Void guessed Ruin was looking for Cyneah.

Honestly, even if Kyran prepared several safety measures to protect Cyneah, he knew that if Ruin got serious, all his preparations would end up useless. Apart from this, when the two met, he would not stand a chance. To be precise, 'Tyr' did not stand a chance against Ruin.

In any case, chances that Ruin would not recognize Kyran was slim. In the end, he would be forced to reveal his real identity and when that happened, his plans would fall out.
