From LuffyNoTomo:

A 30 year old man named Koganei, Manato is down on his luck. He can't seem to get a job, has little money, is still a virgin and is giving up on his dream. Sitting alone on a swan boat in a pond next to a shrine, he holds a lottery ticket thinking this is the only way his dream may come true. But the wind blows it away and he falls into the pond, thereupon seeing a beautiful mermaid!

Manato ends up going back to the pond and after the mermaid decided not to kill him since he gave her food, she tells him about her dream to become human and how she wants to find love (she collects coins and throws them to a shrine in order for her wish to come true). Manato decides he doesn't want to get involved anymore because he has his own worries, but after another bad day he goes back to the pond. She finds him again and after listening to his complaints, she decides to give him all her saved up coins in order for his wish to come true. She suddenly turns into bubbles and disappears.

Confused and upset, Manato hears a strange voice and a god from the shrine comes to say that she will take the coins and grant him a wish. He decides to use his wish to bring back the mermaid as a human. His wish comes true and he sees the mermaid back as a human, but she's a guy! What will happen in this crazy love comedy!?

The lead is a spirit medium, although unfortunately he's not the best. His medium house has lasted for generations, but he only has a quarter of their ability - the only spirits he can call are animals, and while his touch can feel the spirits, he can't even hear them. For that, he needs help from his feline sidekick, although he can only be called half a cat, as he has the past life memories of a dog. Together they aid the animals they encounter, helping them find perspective by exploring their pasts.
