Mecha harem anime. The mecha designs aren't quite as odd as Gad Guard, however the characters are goofy enough to fill in. This is a short, enjoyable series with just enough mecha action to keep you entertained, but focusing more on the main character's daily life.

When a group of children discover a strange cave at the beach, their lives are forever changed. Inside they find a hide out filled with computers and a man named Kokopelli who gives them a curious offer: to participate in a special game in which they save Earth from fifteen giant monsters. To defeat the invaders, he will give them a powerful mecha of black armor. The children eagerly sign the contract, name their new weapon Zearth, and must now take turns to pilot it; but the 'game' is in fact all too real and the consequences of battle become the stuff of nightmares. With no option to cancel the contract, is there any way to stop the game before it is too late for all of them?
Both Bokurano and Gad Guard contain a story driven plot that is accomplished through battles with giant robots. Gad Guard focuses primarily on teenagers whereas Bokurano focuses primarily on younger children, but both casts of characters deal with real struggles that most people in their respective age groups do not deal with, and for that reason I find the two compatible. Also, both series take themselves seriously, though Bokurao is arguably more psychological in nature than Gad Guard.
