Episode 13 (Hanyō no Yashahime)

"The Delicious Feudal Monks" is the thirteenth episode of Hanyō no Yashahime.

Synopsis
Tōtetsu, the final member of the Four Perils, has been wrecking havoc by devouring high-level Shinto monks and priests to attain their increasingly powerful spiritual abilities. One of his targets is none other than Miroku, Hisui's father!

Can the Half-Demon Princesses and demon-slayers reach him in time before Tōtetsu devours him?

Plot
Tōtetsu, the last of the Four Perils is eating monks to increase his power. Taking heed of this, Kohaku sends Hisui, Towa and Setsuna to protect Miroku, who is participating in a 1000-day training course to increase his powers, while Moroha is assigned by Jyūbei to protect another monk. Hisui is dissatisfied at first with meeting his father, as he does not see him eye to eye. While meeting Miroku, they also meet Hisui's older sister Gyokuto, who is paying a visit to her father.

Tōtetsu appears to attack Miroku and attempts to eat him. While protecting his father, Hisui is afflicted by some poison they used on Tōtetsu and the half-demon twins keep fighting the enemy while Miroku tends to him. Knowing that they are in as disadvantage, Setsuna asks Miroku to undo the spiritual seal he put on her to restrain her demonic blood, which unlocks her true dog-demon powers and she forces Tōtetsu to retreat, with Miroku restoring the seal afterwards and Hisui starts seeing his father in a better light.

After the battle, Hisui, Towa and Setsuna bid farewell to Miroku, who now must clean all the mess caused by the battle and Hisui goes to visit his mother Sango that Miroku is safe and continuing his training, while Moroha is disappointed that once again she could not get any bounty.
