Thirteen glanced at the City of Lyra from his vantage point.
After leaving the royal palace, he and Cranky quickly left the city to avoid complications.
If Thirteen wished for it, Cranky could have subdued Rana in twenty moves or less. However, if he did that, the Royal Palace and parts of the city might have been destroyed.
Given how well the Avior Family had treated him during his few days of stay in the palace, he was not inclined to reciprocate their hospitality with cruelty.
Not to mention, the fight could lead to the deaths of innocent people, including Carina, her brothers, and her father, as well as the staff of the palace.
For this reason, Thirteen risked Rana potentially breaking her verbal promise and thus informing the other Celestials about him.
If Rana broke the trust he had given her, then they would be enemies the next time they met.
By then, he would no longer hold back in dealing with her.
