(DBS Interval special Rib Ribbon Edition Gevo Text)
I drew the son of Dr. Gero, Gevo. He was a high ranking soldier in the Rid Ribbon Army but fell to enemy bullets. Who was the enemy of the Rib Ribbon Army during that time, and what struggles did he face? I don't think he was a bad guy, so why did he join the Rib Ribbon Army? I hope someday it will be told!
