An Observation Log of My Wife Who Calls Herself a Villainess - Vol. 4

Accompanying their contracted spirits, Zeno and Kuro, on a visit to announce their marriage, Bertia and Cecil travel to the Spirit Realm. After somehow convincing Kuro's parents to accept the marriage, the group heads to Zeno's family home. But before they can arrive, Zeno's well-meaning older sisters decide to take matters into their own hands. "We'll find Zeno the perfect bride!" Before anyone can stop them, they whisk him away. It turns out the sisters have already chosen his ideal match—Light Sparrow, niece of the King of Light. As Bertia and the others race to rescue Zeno, Light Sparrow becomes increasingly obsessed with making him her own, while directing an intense—and very personal—hostility toward Kuro. Can Bertia put an end to the chaos before it tears apart two lovers destined to be together? The former villainess throws herself into yet another outrageous adventure in the Spirit Realm to protect those she holds dear!
