3rd place: Magical Explorer: Reborn as a Side Character in a Fantasy Dating Sim Vol. 13

With the Susanoo Martial Arts Tournament drawing near, Takine is fired up for battle—but first, he’s thrown into an arranged-marriage event, and his prospective match is Hana Kujo of Amaterasu Girls’ Academy. What begins as a politically motivated meeting soon becomes tangled in the feud between the Kujo and Himemiya families, as well as the schemes of the Beast King. Carrying Hana’s feelings with him, Takine finally enters the tournament, where elite fighters from Tsukuyomi, Amaterasu, and Susanoo all gather. Then his strongest comrade stands in his way: “Kosuke Takine. I’m the one who’ll win this fight.” At last, the cheat-like eroge protagonist and the friend character collide head-on.

Peace had finally returned to the New World thanks to Kirby and his friends—but suddenly, a new crisis strikes!
A mysterious meteor known as the “Dark Star,” said to bring disaster, crashes down, causing the entire world to crystallize!?

To seal away the evil Dark Star, Kirby must rescue the scattered spirits known as “Starly” across various regions, uncover the mysteries of the New World, and restore peace once more!

A new adventure begins for Kirby, Elfilin, Bandana Waddle Dee, King Dedede, and Meta Knight!!

1st place: Cosmic Princess Kaguya!

An overworked, high-spec high school girl × a high-energy Princess Kaguya × a virtual idol!?

A little way into the future.
Iroha Sakayori, an overworked, ultra-capable high school girl living alone to focus on getting into the University of Tokyo, is on her way home one day when she finds a mysterious baby—emerging from a rainbow-glowing “gaming utility pole”!

But that baby rapidly grows up right before her eyes, turning into a spoiled girl who absolutely adores Iroha!
Claiming she came from the moon, the girl is named “Kaguya” by Iroha.
However, once Kaguya learns how The Tale of the Bamboo Cutter ends, she makes a bold declaration—

“I’m going to make it a happy ending. No matter what!”

And then, for some reason, she sets her sights on becoming a top idol in Japan’s largest virtual world, “Tsukuyomi”…!?
