How did Xylo get engaged to his fiancée Frenci in Sentenced to Be a Hero? In this video, we break down the full backstory behind Xylo Forbartz and Frenci Mastibolt’s engagement, including the tragedy that led to it and why Frenci still considers them bound today. Spoiler warning.
After Xylo’s family was wiped out by the demon blight, he was left as the sole survivor and lost his family territory. The Mastibolt family took him in and raised him as their own, but as he grew older, the issue of his bloodline became unavoidable. Believing it was his responsibility to ensure his family line didn’t end with him, Xylo accepted an engagement to Frenci despite having little real choice.
The two swore a formal oath under the laws of the Night-Gaunt clan, an oath that is legally binding and marks them as fated to marry. This is why Frenci insists the engagement still stands, as the oath was never officially revoked. Xylo, however, believes that becoming a penal hero stripped him of the right to marry, creating a lasting rift between how they view their past and their future.
