The episode begins with Ryota, Celeste, and Emily considering moving to a new house because Celeste feels uncomfortable during magical storms. They find a house built with storm-proof construction methods, and despite the high rent, Ryota decides to take it to ensure Celeste's and Emily's comfort.

Afterward, the trio focuses on preparing for the upcoming Harvest Festival. They venture into the 7th level of the Telulu Dungeon, where they encounter a rare monster called High Slime. Through teamwork, they manage to defeat it and obtain a valuable jewel that reflects attacks.

After selling the jewel to Erza, Ryota receives a large sum of money due to the approaching Harvest Festival. At that moment, a young girl named Alice approaches Ryota and asks to join his party. Alice had been rejected by other adventurers because her maximum level is only 2. Ryota agrees to take her with him, and they head into the Nihonium Dungeon to level her up.

Alice reveals that she was born in a dungeon and can sense where monsters are located. She quickly reaches her maximum level, and they discover that she cannot progress any further. However, Alice possesses the unique ability to communicate with dungeon monsters. She befriends two monsters, which she names Bonesy and Jiggly, and they accompany her in battle.

Back at home, Alice meets Emily and Celeste. Emily cooks carrot hamburger steaks, leading to a humorous moment where Eve proposes to her out of love for carrots. Alice, Bonesy, and Jiggly are officially welcomed into the Ryota family.
