After dinner, Usagi Ozaki produces the now cleaned saya that was found on the ogre.
"This is the scabbard of the Hare clan ancestral sword - lost to us for many years.
"Five hundred years ago, this saya was worn by Usagi Gohei when he and only fifty samurai held this castle against two hundred Bloodspeakers, led by the black sorcerer Iuchiban himself When his wife, Usagi Furiko, returned with reinforcements from the Lion Clan, she took the sword from her husbands corpse and struck down Iuchiban with it.
"Two hundred years ago, there was... an anamorous entanglement Usagi Nidei and a Crab Clan samurai. He knew that she had entered the Shadowlands and not returned. Nidei begged his mother, the daimyo, for permission to pursue her. She refused — but that night, Nidei fled the castle to rescue his love, taking the clan sword with him. Since then it has been missing.
"Now we have a clue at last."
When summoning the kami in the saya and asking it where the sword currently resides it replied "Haikyo sano Kappa", the fallen Hiruma fortress in the Shadowlands.
