While Shou Toramaru is a youkai, she is also an incredibly auspicious being who attracts wealth and treasure. Her presence at Myouren Temple might explain why it's popular with humans even though it's a den of youkai. She is also known for misplacing her Jeweled Pagoda.

Hong Meiling is the Scarlet Devil Mansion's gatekeeper, who occasionally sleeps on the job. One peaceful day, when she was about to doze off, she noticed a mouse with a pair of dowsing rods approaching the mansion. The mouse tried to pass through the gate, so Meiling stopped her. But that didn't deter the mouse, who was determined to get inside the mansion no matter what. Meiling's face lit up as she finally had some work to do.

Bishamonten is the protector god of the north. When worshipped individually, he is referred to as Bishamonten, but when worshipped as part of the Four Heavenly Kings, he is called Tamonten―the All-Hearing Deva. In Japan, he is also known to bestow good fortune as one of the Seven Lucky Gods.

Nazrin returned to Shou with her tail between her legs. Concerned, Shou asked what happened. Nazrin explained that the Jeweled Pagoda was in the Scarlet Devil Mansion, but she was denied entry by the gatekeeper. Furthermore, the gatekeeper even challenged her to a battle saying, "If you want to get through this gate, you'll have to get through me first!"

Shou stepped up to Meiling, who stood impassively with the gate at her back. Unfortunately, Shou's demands for the return of her Jeweled Pagoda were met with ignorance. "If you refuse to stand aside, I'll make you," declared Shou as she brandished her spear. The mistress of the Scarlet Devil Mansion must have had an excellent time as she drank some tea while looking down at the martial arts battle that unfolded.
