Re:ZERO -Starting Life in Another World- Short Story Collection, Vol. 4 (light novel) — Tappei Nagatsuki

A collection of tales behind the scenes of the main story and away from Emilia's camp! Follow the Golden Lion and the Sword Saint as this unconventional master and servant come to a compromise that proves hard to keep. Witness as the kingdom is rocked by an outbreak of zombies. And finally, read about Otto's struggles in his bittersweet travel log. Babies, zombies, and slaves -- oh my!
