A stint at the cat café to cover for Miss Sato unexpectedly leads to Mr. Kanda taking part in an impromptu rescue to save a kitty in need! The charge is led by the café manager, who ropes in Mr. Kanda and Teruaki Kuju, one of Mr. Kanda's former pupils who happens to be in the right(?) place at the right(?) time.

But when Kuju is tasked with bringing the cat back to the Kanda house after a successful, if intense, rescue, will his guilt and fear over what happened with Hoshinari in the past prevent him from seeing the mission through? And how will Fukumaru deal wth yet another feline interloper on his turf?!
