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~)

The first expansion is a mini-expansion designed for 1-2 player counts, with the appearance of NPC adventurers. These NPCs can take on quests, but risk failing and turning it into an emergency quest.
