Discovered as the only true disciple of Goomoonryong and entrusted with the Phoenix Medallion of the Sunwoo Clan by Lady Sosul—making him the interim leader of the Sunwoo Clan—the world of Murim is not so eager to let Shioon leave. With his new status, enemies Shioon has never encountered before keep appearing before him, such as the organization known as Soldiers Under Command. They are intent on getting rid of him for the sake of their own prosperity, but how will Shioon defend himself without his ki-center intact?

Yagi, Norihiro

Whispering the name Seiichirou Kitano is enough to send shivers down the spine of any student at Hekikuu High. His fearsome looks make even the toughest of men scream, and if his appearance isn't off-putting enough, he is also known to be extremely brutal in fights. In a single day, he took out the school's top thug and became the new guardian. Now, the entire school is at his mercy, and anyone who dares to challenge him better be ready to meet their maker... or so the stories go.

The truth is that all of the terrible rumors surrounding Seiichirou are misunderstandings, many assuming the worst about him because of his demon-like features. In reality, he is a kindhearted boy who goes out of his way to help others, but his attempts to do good deeds always get hilariously skewed and miscommunicated—which was the case when he became the new guardian. 

Time and time again, Seiichirou tries and fails to prove that he is not the demon that rumors make him out to be. He hopes to one day be able to have friends who look beyond his scary disposition and see him for what he truly is—an angel.
