The Hamabe no Ground (浜辺のグラウンド, Hamabe no Guraundo, lit. Ground of Beach) is a soccer field located in Raimon's era.
That's where Alpha teleported Tenma in episode 1, to show him soccer has to be destructed. His team, Protocol Omega arrived and they started shooting at Tenma using the Sphere Device's Strike Mode. As Alpha was going to shoot, a mysterious man appeared and grabbed the ball, and was revealed to be Fei. Then, he duplicated himself into some Dupli and gave the captain's band to Tenma, so they could play against Alpha's team. Fei called the team Tenmas as the captain was Tenma, and the match started.
