Plot
Kaga realizes clothing stores are willing to pay for monster rabbit skins and begins hunting them. Reaching the seventh floor boss, Kaga and Roxanne find it is a Rapid Rabbit that drops quality meat as loot, which Roxanne turns into a fine dinner. They decide to defeat the Rapid Rabbit again but meet another adventurer who has been on floor six for years preparing to fight the Rapid Rabbit. Unfortunately, the Rapid Rabbit kills him. Kaga is deeply affected by this and is unable to come to terms with the realization that adventurers die in labyrinths all the time and one day it could be him or Roxanne. After Roxanne spends the night comforting him, he resolves to get over his depression. They sell their rabbit skins and Kaga purchases silk camisoles for Roxanne. On the seventh floor, a bull monster breaks Kaga's finger, and though he recovers by magic, he is again affected by how dangerous the labyrinth is becoming. While bathing he introduces Roxanne to oral sex. The next day, Roxanne realizes a monster has finally dropped a Skill Stone as loot, the kind used by dwarven blacksmiths to add magic skills to equipment.
