So Moonjoo (소문주, Somunju), also known as Biweol, the Lightning Blade (뇌격검 비월, Noegyeoggeom Biwol; "Lightning Blade Biweol") was the younger half-brother of Heukweol, and the son of Lord Moonjoo. He was also a member of the Secret Sword School (비도문, Bidomun) led by his father.
Appearance & Personality[]
He was a youthful looking man with long hair that draped over his face slightly obscuring it, and he also tied it into a low ponytail. Biweol wore the standard clothing of the time and carried a large blade around.
Biweol was a psychotic man who was willing to kill on whim. He even stated that once he drew his sword, blood would be spilt. Furthermore, he liked to draw large and intricate images in the ground, sometimes with blood. Biweol was also extremely confident in his own abilities and only moments before his death had he shown true fear.

Yongbi the Invincible - A Side Story[]
Volume 1[]
When the Secret Sword School was commissioned by Yuk Jingang to hunt down Yongbi, Biweol was involved due to being a member of it. While on the job, he stopped to sketch an image into the ground. Meanwhile, Yongbi and Biryong went down the very path he was sketching on and Biweol called at them to halt, before threatening them not to ruin his drawing. He then drew his sword, preparing to kill, but Biryong jumped over and left. As the other party left, Biweol expressed surprise that someone was able to make him draw his sword without shedding blood, adding that he wanted the horse as well.
Then his subordinates arrived and they made their way to the home of an elderly couple, slaughtering them. Yongbi later reached the residence as well, and discovered that the old couple was dead. After Yongbi noted the old man's name as "Hwang" (later revealed to be the parents of Hwang Inbok, a member of the Black Lancers), Biweol realized that Yongbi's showing up at the home was not a coincidence and prepared to attack. Yongbi proceeded to take down his subordinates before killing Biweol.
Powers and Abilities[]

He is presumed to be a proficient martial artist since he was trained to be the heir of a powerful family, and having earned the title of "Lightning Blade". However, he was completely no match for a warrior of Yongbi's calibre who dealt with him effortlessly.[1]
In addition, he was trained from childhood in many sword art styles[2]:
- Chundu Jetan
- Eunha Bimu
- Mansan Sengmyul
