Sun-Ken Rock is a Japanese manga series written and illustrated by Boichi. The plot tells the story of Ken, a high school delinquent turned down by the girl he loved, Yumin, who promptly left Japan to become a police officer in Korea. Yearning to see the girl he loved, Ken dropped out of high school to travel to Korea and become an officer just like Yumin. Though Ken managed to travel to Korea, he found himself unable to become an officer and instead became a poor Shut-in with no money or job. After saving an old man from being abused by a group gang members, he was scouted by the head of a local gang led by Tae-Soo Park, who made him the new boss. The manga was licensed by JManga, but is now available through a read-only/print-only subscription at BookWalker and Crunchyroll.

Plot
The story revolves around Ken, a man from an upper-class family that was orphaned young due to his family's involvement with the Yakuza; he became a highschool delinquent known for fighting. The only thing that motivates him to take action is through his romantic affections for a classmate, Yumi. After learning she decided to move to Korea to become a police officer, Ken left his life in Japan behind and tried to follow in Yumin's footsteps; due to unforeseen circumstances, he incidentally becomes the head of a local gang and tries to hide it from Yumin. As the leader, the gang is renamed the Sun-Ken Rock Group. At the first, the gang only consisted of few members and didn't even have a base. As the story progressesThe Sun-Ken Rock gang becomes bigger as they recruited new members and take over other gangs' territories and investments. The Sun-Ken Rock Group acquires an MMORPG company, a large casino, one of the biggest television media companies in Korea, as well as garnering political favors. However, throughout all of this, Ken has done his best to evade revealing himself to Yumin as a gang leader as she despises gangs. Ironically, Yumin was groomed to become an advanced plant in Korea to help her Yakuza group lay the foundations to expand their hold into South Korea; due to Yumin's refusal to join the "family business," their plans were stalled as various members either tried to take her back to Japan or try to get her back into Yakuza control. In between Ken's rise, he and Yumin got closer and Yumin started to have feelings for Ken. However, things were always complicated by the interference of either Ken's gang activities and/or Yumin's Yakuza connections. The series, despite being very adult-oriented, espouses many shonen-esque values, such as the importance of friendship and the concept of being a "true man". The turning point in the story was when she was kidnapped by her own group and Ken was exposed as a gang leader in his attempts to rescue her from his greatest rival, Kim Ban Phong. The manga has three spin-offs "Dango Knight ", "Sun Ken Rock Gaiden - Yumin" and "I Want Feed Yumin".
