Riviere and the Land of Prayer, Vol. 2 (light novel)

ONE PERSON'S TRASH...Can you pleeease try to be serious for once, Miss Riviere? Ugh, anyhoo, welcome back to Riviere Antiques! The cases Miss Riviere and I will tackle this time around include searching for a serial killer, helping out an insomniac, crashing a secret party, collecting super-important sancta, sharing some love advice with a friend, and keeping the peace at a doll exhibition. Meanwhile, Antiques Carredura and their dangerous sancta are up to the same old shady business. Surely, the trio of myself, Miss Riviere, and the Ashen Witch, Elaina, can solve these problems without any complications at all, right...? Right?!
