Hyperdimension Game Neptune ~Megami Tsuushin~

The cast of Hyperdimension Neptunia in a high school setting.

After years of fruitless war between the four realms of Gamindustri over Share Energy, the source of their strength based on how much their people have faith in their goddesses, the four CPUs that rule over them have finally signed a treaty of friendship. The treaty prohibits any attempt to use military force in the hope of bringing peace and prosperity to their worlds. And, a month after the deal, Neptune, the CPU goddess of Planeptune, spends her time playing games rather than doing her work, leaving the shares of her land plummeting. (Source: MangaDex)
