The story follows Caesar, the pet dog of Ryosuke Kagami (nicknamed “Erosuke”). Famous as the most charming “ikemen dog,” Caesar suddenly gains the ability to take human form. This unexpected transformation throws him into a series of wild, chaotic situations involving women, while also dragging in Kyur, a partner bound to him by a shinigami contract. Packed with slapstick humor and risqué antics, the series shows Caesar swept up by desires and troubles that Ryosuke himself knows nothing about.
