The Nobinata Gambit

Shakiro Nobinata wakes from life-saving surgery to discover he is paralyzed from mid-chest and re-growing several organs as well as his spinal cord. Lilo, who it turns out is really named Yuki Karaguchi, has been tasked with "assisting with recovery" by Shakiro's father, Clan Lord Feng Nobinata.

Shakiro's parents ask him to come home to the Empire of Nippon and Allied Cultures for his convalescence. He takes Yuki and her terminally ill mother (the original Agent Karaguchi) with him, only to discover his father's true motivation is a mysterious disappearance of a distant relative of the emperor; Nobinata is the clan in charge of Imperial Security, so any missing member of the royal family is a big problem. And the Emperor himself is coming to the planet in a few weeks.

So Shakiro has to learn how to walk again, convince the intriguing woman who has seen him at his worst to stay with him, find a traitor to the empire, and plan a Buddhist funeral, all in the few weeks before the Emperor arrives for his Golden Jubilee celebration…and possible assassination.
