A new home filled with the ghosts of Shiba Inu. What could go wrong?

When high schooler Kori Momose goes apartment hunting to be closer to her new school, she comes across a one-bedroom unit at a shockingly cheap price. What’s the catch? The ghost of a Shiba Inu dog named Mu is bound to the apartment! But for a girl as icy and awkward as Kori, is sharing a life with the fiery Mu too tall an order? A funny and heartwarming odd couple comedy begins right here!

For the first time, Kori has to go on a trip and leave Mu by himself overnight. Mu enjoys his freedom at first, but when it’s time for bed the apartment feels a little too empty. Also, Valentine’s Day is approaching, and the Jiba are all excited to try chocolate. When the gluttonous Croquette is told dogs can’t eat it, he organizes a hunger strike, but to what end?
