Hi☆Light: Crystal of Light focuses on the four Goddesses of Gamindustri, and their relationships with their sisters.

In a world known as Gamindustri, four Goddesses and their sisters use the power of Shares to rule over their respective nations – the Goddess Neptune of Planeptune, Noire of Lastation, Blanc of Lowee, and Vert of Leanbox.​​

Though originally in competition, the Goddesses formed a Treaty of Friendship to bring peace to the land and free up time for them to do what they enjoy. However, nefarious crime syndicates, rival Goddesses, and a bevy of ne’er-do-wells will test the strength of their relationships and their very existence. What awaits the Goddesses, and will Neptune ever get a chance to clear out her gaming backlog?!​​

Hi☆Light: The Blazing Bifrost focuses on the parallel dimensions of Gamindustri, and what happens when they become intertwined.

What happens when more than one version of Gamindustri and its Goddesses are revealed to exist, and what awaits the Goddesses when the fate of the two dimensions become intertwined? Hopefully, there’s pudding at the other end of this dimension…​​
