American Kitsune, Vol. 4 (Light Novel)

The fan service continues...

Two weeks have passed since Kevin Swift was kidnapped by spandex-clad secret agents, rescued by Lilian, and they were both subsequently saved by Lilian’s faithful maid-slash-bodyguard. Since then, Kevin has nabbed himself a foxy girlfriend—pun very much intended—and a person willing to train him in the arts of badassery. Needless to say, life has been good.

Then Lilian's family decided to pay a visit.

And everything went to hell.

Sometimes, life gives you lemons. Other times… well, you get the picture.
