“Sumo-bots, ready?” the announcer called. “Three… two… one… Hajime! ”

The bots shot forward. Crusher roared, its massive wheels spinning, seeking the edge of Samson . Leo’s bot moved slowly, deliberately. It didn’t charge. It just rolled to the center and stopped.

Mia laughed, a real one. She reached over and offered a fist bump.
