Hoshi no Shima no Nyanko

Neko no Sumu Shima (The island where the cats live) takes place in Tashiro-jima, a place called "Island of the cats", which was severely damaged by the March 11 earthquake and tsunami. This 5 minutes episode follow the story of cats after the disaster.

Based on a series of Chiikawa comics posted on X by Nagano from March to November 2023, known as the "Siren Arc" . One day, while Chiikawa and Hachiware were relaxing in the square, Usagi suddenly appeared with a flyer stuck to its face. When Hachiware checked the flyer, it was an invitation reading “Special Invitation to a Special Island.” Lured by promises like “Get 100x rewards for simple island quests!” and “Limited-edition island ramen, exclusive sweets—sweet and spicy treats all practically free!”, Chiikawa and the others decided to go on the island retreat. Boarding the ship alongside Rakko, who was suspicious of the flyer's contents, the group landed on the island... only to find something waiting for them there...!?

The story centers on a woman who is getting on in years, but all her cats think she's a man so they call her Ojii-chan. One day a brazen cat named Tsushima appears in Ojii-chan's yard.
