Episode 4

Episode 4 is the fourth episode of the anime series.

Summary
Boxxo is kidnapped by thieves, including Gugoyle, the hunter who tried to break him open previously. Around this time, he upgrades his durability when they try to damage him. They take him to their hideout with a kidnapped magic item engineer, who turns out to be Lammis' friend Hulemy. She and Boxxo quickly become friends and with her expertise, she realizes Boxxo contains a human soul. That night, the thieves sneak in to attack Hulemy, but Boxxo persuades them to leave by dispensing pornographic magazines. The thieves' leader gives her two days to break Boxxo open or she will die. Boxxo helps her out by providing her with food and bath supplies to clean herself. Shortly before the deadline, the hideout is attacked by Lammis and the Hunter's Association in search for Boxxo. The attack sets off explosives that buries Boxxo and Hulemy under rubble. They survive inside Boxxo's shield while he also provides Hulemy some oxygen when she begins to sufficate from the thin air. Hulemy also uses coins from the thieves' stash to give him enough power to maintain his shield. Lammis eventually finds and reunites with Boxxo and Hulemy. Kerioyl is revealed to have uncharacteristically aided in Boxxo's rescue for free by capturing the thieves, though he insists it is a ploy to eventually have Boxxo join the Menagerie of Fools and help Kerioyl achieve his dream.
