Catch the Rainbow (On a Stormy Night...) (story arc)

Catch the Rainbow (On a Stormy Night...) (キャッチ・ザ・レインボー（嵐の夜に…）) is the twelfth story arc in Steel Ball Run.

It narrates Lucy's escape and confrontation with Blackmore, while Johnny and Gyro race against Diego in the storm.

Summary
Blackmore takes the Spine from Lucy. Calling Valentine from a nearby telephone pole, he is distracted by a vision of Jesus Christ and his own greed toward the Corpse, allowing Lucy to shoot him and escape again. Exalted by the miracles he witnesses around him, Blackmore seals his fatal wounds with raindrops and pursues Lucy.

Meanwhile Gyro and Johnny are unable to get ahead of Diego. In the tempest, Gyro and Johnny struggle to find the optimal path while Diego's enhanced senses help him. Gyro decides to challenge Diego anyway, and using his instincts to follow the path that he decided for himself, Gyro inadvertently gets right behind Diego, having chosen the same path as Diego. Diego aggresses Gyro's horse with transformed fleas, prompting Johnny to shoot at Diego. The British is finally defeated when Gyro throws a Steel Ball at him and Diego's horse Silver Bullet hurts its leg, throwing Diego out of the race. Gyro remains unsatisfied that his victory was made with Johnny's help, as he guesses Diego wasn't utterly defeated and will come back at them.

The duo then meets Lucy and Blackmore almost at the same time and a fight ensues. Catch the Rainbow immobilizes Johnny and Gyro, but the latter manages to throw a steel ball on Blackmore by evaporating some raindrops. Blackmore dies from his wounds, and the Spine enters Johnny's body as the weather calms itself, and the next Corpse part's location reveals itself to the duo.
