[Updated daily with 3,000 words. If there's no update one day, there will be one the next.]

Yamada Yuzu is a poor office drone who diligently worked at his company for seven years before being laid off. After looking back on a first half of life that was exhausting and utterly unremarkable, he decided to give up trying. By sheer luck, he won a prize drawing for the hottest idol-raising virtual reality game. For the first time in his thirty years as an office drone, he discovered the joy of gaming:

[Flowers of Darkness]

A certain floppy-eared rabbit, an important member of the Port Mafia, starts vanishing regularly after investigating the Black Lizard's recent mysterious movements. He becomes an obsessive solo fan. All it takes to go from scoffing at the idea to never missing a show is one stage. A certain bandage-wearing man from the Armed Detective Agency wanders into a suspicious live house while on a case, then happily decides to hold all the agency's future team-building events there: [Pirate - Lucy] [Witch - Tsushima Shuki];

[Demons of the Sea]

To improve further, the new idols are scattered across different locations and time periods in different worlds. Only by becoming more famous can they return to their original worlds. And so:

Tsushima Shuki arrives at Marineford and uses his seastone-like broken ability to blend in with the Marines;

Sakata Ginco drops into Cake Island, makes a powerful friend who shares her interests, and eats and drinks her way around the island and its neighbors until the wedding begins and she realizes something is wrong;

After the tiny Shen Wei meets a gifted kid in sunglasses, she decides to train him to become strong;

Lucy finds her own pirate ship and sets off on a whole new adventure with two captains;

Saiki Kuriko wakes up on a ship flying a pirate flag with a white mustache on it. After spending some time with the crew, she decides to set off for Cake Island.

[School Idols]

A new branch of an idol agency has recently opened in Namimori Town. With it come mysterious transfer students and new teachers, launching a series of school idol activities...

-

Under Yamada Yuzu's management, the girl idols gradually grow, shining on stages across different worlds and gaining countless fans. He also becomes a top agent. In real life, he receives an award for outstanding players from the game company and finally escapes the life of an office drone constantly rushing from place to place.

But he doesn't know that the rumors people spread about him are nothing like what he imagined:

He's willing to do anything for inspiration, even becoming the mastermind behind several sensational crimes. His hands never touch blood; he is merely an observer of human nature.

He's an ambitious warmonger who claims to stand for peace while seeking to control the world. He disregards every side and every force. Anyone who stands in the way of his campaign gets dragged onto the battlefield.

He's a mysterious teacher whose purpose is unclear and identity shrouded in secrecy...

[All the idols are gender-swapped male characters. For characters whose gender-swapped names already exist in the source material, I've kept them. I made up the rest, so please leave better suggestions in the comments!]

[The blurb doesn't include every gender-swapped character, and the order here doesn't indicate when they'll appear.]

[Content warning: Lots of awkward stage descriptions and made-up original lyrics.]
