Due to extreme fatigue and
terrible work conditions, Routa dies without having done much with his life. As
he breathes his last, the only thought in his mind is to be reborn as the dog of
a rich family so he can enjoy the good life. A merciful goddess takes his plight
to heart and grants his final wish, sending Routa to be reincarnated as the pet
of a wealthy young lady! It seems like he got exactly what he wanted, but it
soon becomes clear that he's much too large, much too powerful, and gets in too
much trouble to be any regular old dog!
