Ryuki's First Battle is the sixth chapter of the manga Kengan Omega.
Koga escapes the hospital (after trashing it) and he and Akiyama head down to the venue to watch Ryuki's Kengan match debut. Sene Rarumaru reveals the fight is over the rights to purchase a food processing center. With all the Kengan Association members mistaking Ryuki for Tokita Ohma, the fight between Gaoh Ryuki and Utsubuki Kokuro begins!
- Kaneda Suekichi and Himuro Ryo can be seen in the background when Ryuki makes his first public appearance.
