Detective Conan: The Nth Shura Field

You can start reading from Volume Five. The earlier volumes aren't as good.

Yan Shuyao, a die-hard Detective Conan fan, was on her way home one day when she was suddenly surrounded by cats and dogs that had dropped out of the sky:

a golden retriever (Rei Furuya), a ragdoll cat (Hiromitsu Morofushi), a black cat (Jinpei Matsuda), a Samoyed (Kenji Hagiwara), a husky (Wataru Date), a Maine Coon (Shuichi Akai), a corgi (Shinichi Kudo), a Shiba Inu (Heiji Hattori), a Persian cat (Saguru Hakuba), and an elusive white cat (Kaito Kid).

Yan Shuyao: “...Have all the great detectives turned into adorable pets?”

Even more absurdly, these cats and dogs could not only understand human speech, but also solve crimes, cook, fight, race cars, and even... compete for her attention?!

Rei Furuya (golden retriever): “Woof!” (Translation: Shuyao, ignore that black cat. All he does is wreck the house.)

Jinpei Matsuda (black cat): “Meow!” (Translation: You golden mutt, quit pretending to be a good boy!)

Shuichi Akai (Maine Coon): “...” (Translation: Hmph. Childish.)

Kaito Kid (white cat): “Meow~” (Translation: Miss, the moon is beautiful tonight. Would you like to steal the stars with me?)

Yan Shuyao: “...Have you all forgotten you're cats and dogs?”

But as they spent more time together, they gradually discovered that a little cuddling with her let them briefly return to human form?!
