Wanting to create a world made entirely of lard, Buta attempts to steal the Legendary Lard, but Milky Holmes stands in his way. Meanwhile, Arséne, who is in London, encounters Sonia, who attempts to convince her that Milky Holmes haven't lost their way. As Buta manages to retrieve the Legendary Lard and starts absorbing lard from across the globe, Milky Holmes stand up to them and regain their Toys and work together to fight against Buta. Undeterred, Buta fuses himself with the lard he has amassed to evolve into a new form, but Arséne manages to get herself across the globe to stop him, allowing Milky Holmes to use Arsene Lupin's straw to defeat Buta and return the lard to its rightful place. As snow falls over Yokohama, Arséne reunites with the Gentlemen Thieves.
