らくらく冒険者の幸せ異世界ライフ　ミニ拡張　～冒険者たちの間奏曲～ (Rakuraku Boukensha no Shiawase Isekai Life Mini Kakuchou ~Boukenshatachi No Kansoukyoku~)

This is the first mini-expansion for 1-2 players that introduces NPC adventurers to the game. These NPCs can take on quests, but they risk failing, which turns the task into an emergency quest.
