I Like Villains, so I Reincarnated as One Vol. 2 (light novel)

After waking up as Weiss Hamilton, a doomed minor villain from his favorite game, one fan has been working hard to rewrite the plot! He's already saved two other characters from their tragic fates and turned his mismanaged territory around. It seems like he's finally avoided certain death—until a neighboring noble declares war! Framed for involvement in the slave trade and isolated from help, Weiss relies on his game knowledge to craft a perfect strategy to save himself from another game over. But when Weiss's sister suddenly returns from the capital, old tensions between them threaten to blow apart his carefully laid plans!
