Mushoku Tensei: Isekai Ittara Honki Dasu - Eris no Goblin Toubatsu

While Dead End spends a day in Millishion attending to separate errands, Eris decides that sitting around is not an option. She accepts a goblin-slaying job and soon crosses paths with Cliff Grimoire, a talented young mage whose confidence is almost as large as his ego. Despite a rocky introduction, Cliff stubbornly follows Eris into the forest.

Their supposedly simple hunt takes a darker turn when they stumble upon assassins pursuing a young girl and her protector. Eris charges into the danger without hesitation, while Cliff gets a firsthand look at the strength, recklessness, and fierce loyalty that define the swordswoman he has just met.
