"Despair not, my child," you declare, "for unless you have mislead me, your visions did instruct you to fight the demon alone. Your band will be joined in battle by your father, Senshinochi, mightiest among the Kappa."
You send for your husband, and instruct your host to hastily assemble a makeshift arena. While you wait, Ken entertains you with stories of his life in Kappa country. He has been traveling with his disciples for the last several years, ever since his twin brother Okurimono obtained the title of dojo quartermaster. Your son admits that he despises his brother, but refuses to dishonor his bloodline by speaking ill of such close kin, so you do not know how the pair fell out or why Ken was banished from the dojo.
As lunch is served, Senshinochi asks his son about his lovelife, and the kappa sheepishly beckons one of his followers, a young female, to rise and present herself. "This is Uminootome, my companion in life and rival in skill." he declares, "she is of too low birth to ever be my wife in the eyes of Kappa law, but I have sworn on my honor to love and defend her so long as we both live. She has made grandparents out of you twice over, but sadly neither child survived infancy."
Your common law daughter in law offers you a low bow, a nod, and a smile. "Please do forgive her silence. She has taken a vow to eschew the spoken word until my quest is complete, so that we may find favor and luck in our gods."
Eventually the arena is ready, the demon is brought out, and the fight begins.
8!!!
The fight is over in but a moment! You husband calls the lighting to smite the demon, and the first bolt partially paralyzes and stuns the beast. Ken, his father, and his followers quickly rush to pin the demon down. You can tell age is starting to catch up to your husband, as it takes him a good deal longer to close the distance than it did in his youth, but once the giant kappa arrives in melee range he completely overpowers his foe, applying a full nelson and holding it for several minutes so that Ken may hack the demon's leg off with his claws!
Eventually the limb falls free, and your son holds it above his head in triumph!
"It is not done yet son," your husband declares. "This demon is damaged beyond repair. It would be disgraceful to leave it suffering like this. Slit the beast's throat. Its remains likely hold enough essence for your mother to craft you a boon at no further cost to herself."
You ponder your husband's claim, and decide that he speaks the truth.
A: Yes boy! Slay the demon! I will craft you a mighty gi from its flesh and fur!
B: Yes boy! Slay the demon! I will craft you a sword from its other femur, so that the blade Sun-nut must make you will have a twin!
C: Yes boy! Slay the demon! From its skull I shall craft a crown for your lover Uminootome, and bestow on her a title so that she may become your wife true and proper!
D: Yes boy! Slay the demon! I will craft a fetish from its heart to greant you the secrets of restoritive magics!
E: Yes boy! Slay the demon! I will craft a fetish from its scent glands to grant you the secrets of toxic magics!
F: Honey, you kill it please. The boy is already getting an artifact out of this, so I shall use the rest of the demon for my own purposes.
G: STAY YOUR HAND! Return the wretch to its cell. Perhaps I will find use for it even in its crippled state.
