Shimei Ryomou
  
Personal Information
Shimei Ryomou (子明呂蒙), her historical character is Lü Meng. Her seiyuu is Yuko Kaida. Her hair / eye color is blue / green. She is from Nanyang Academy (Nanyo Gakuin), 3rd Year Student. One of the Four Devas of Nanyo.
An odd girl with short blue hair and 
green eyes, a distinctive mole on her left cheek and a very strange history, 
mainly tied to her mysterious left-eye patch. She is one of the Four Devas of 
Nanyo. She has a habit of wearing a blue miniskirt French maid outfit and 
specializes in pro-wrestling moves, throws, and joint attacks, which she uses in 
conjunction with a pair of handcuffs she carries; she is also very proficient in 
making energy blasts. Her earlier life before she became a Toushi is unknown but 
is hinted as being tragic and painful. She, Teifu, and Saji have been best 
friends long before the start of the series. Her dragon appears to be her own, 
though how she got it is not known Presumably because of that, she has a minor 
split personality; one is fairly normal and the other is psycho-sexual. Her 
psycho side is not nearly as bad as Ryuubi, Sousou and Hakufu. No other 
characters seem to be in harmony with their dragons as much as Ryomou, but she 
still seals it with her eye-patch and is believed to be dying because of it. 
While she has it, she is as powerful as the other Three Rulers. Her magical eye 
may a reference to the Chinese idiom "To look at a person with a new eye" or 
re-evaluate them or not to judge them by their appearance, an idiom attributed 
to Lu Meng who was as a brilliant scholar as he was a warrior.
She is not shy and acts uninterested in relationships. In one scene she isn't 
even phased when Saji puts his hand down her shirt and gropes her. Her magatama 
is shown as being silver and she is arguably as strong as Myousai, though she 
retreats during their first battle in order to protect the Dragon Jade. She 
appears to be close to Hakufu and goes out of her way to help the Nanyo leader 
whenever she can. She went out on her own to find the Dragon Jade even to save 
Hakufu. She was badly injured after being ambushed by Teni. Chou-un came to her 
rescue but Ryomou awakened her own dragon, defeating Teni. Chou-un was able to 
knock out Ryomou, bandage her up and return her to Nanyo after stealing the 
Dragon Jade. Chou-un stated that if Ryomou was not injured during the awakening 
of her dragon, Ryomou would have been able to defeat her. Ryomou recovered to 
full strength and played a part in the Battle of Chibi, defeating Myosai. She is 
now working alongside Hakufu in a cosplay cafe, dressed as a cat maid (Ryomou 
even wears a heart-shaped eyepatch).
