Also is this London reasonably close to the real life London in size? Something moving at the speed of light can fly around the parameter of London ~1500 times in a second. Flattening the remains of London is a few seconds isn't all the impressive compared to that. Marisa isn't as fast as light and it's hard to say exactly how far down from it she is. However, I don't see anything that suggests she couldn't run circles around Kid Miracleman.
My current perception of the fight is Kid Miracleman will immediately go on the offensive and try to kill Marisa. Marisa is just simply too fast and will dodge the initial attacks. Marisa will fly around dodging all of the rest of Kid Miracleman's attacks as well. She'll flood the field with projectiles which Kid Miracleman can tank. After a few failed attempts, she'll bust out the Master Spark. With her speed and speed of the attack, Kid Miracleman shouldn't be able to dodge. It comes down to just how strong Kid Miracleman's durability really is. Can he really stand up to repeated attacks from power that can reduce a single mountain to ashes? If he can't, Marisa should win. If he can, Marisa has lost. He'll get his telepathy to work eventually and be able to tag Marisa.
