A Family of Martyrs, So What If I'm a Profligate?

In my past life, I was the nation's blade. After killing the last man, I was silenced by my own people. In this life, the memorial tablets filling the hall are my father, uncles, and brothers—they didn't die in battle; they were murdered by the man on the dragon throne. By day, I am the capital's number one profligate, enjoying poetry, wine, and romance; by night, I am the Night Owl, making those who harmed them afraid to light a lamp. — Description from novelcodex.org
