Betrayal? (裏切り？) is the twenty seventh chapter of the DanMachi manga.
Bell got ready to fight as the Orc used the Landform to get a weapon. He clashed with the monster and managed to cut off one of its legs. At that moment, an arrow shot out and shot his left holster off which put his Hestia Knife out of reach. Bell tried to look around for the attacker but had to force his attention back to the monster. He used Firebolt and successfully killed it.
At that moment, Lili announced the end of their partnership while taking the Hestia Knife. Bell tried to run over to her only to find that she'd attracted four more Orcs using an item to attract monsters. Lili told Bell to be more suspicious of people and ran off, leaving Bell alone to face the monsters.
