The song is scheduled for release on Wednesday, April 8, 2026, and fans can also look forward to the official music video premiere at 8:00 PM (JST) on the same day.

About the Anime: A Unique and Humorous Isekai Story
The anime stands out immediately due to its unusually long and quirky title. However, beyond the humor lies a creative and refreshing take on the isekai (reincarnation) genre.
Beginner-Friendly Story Overview
The story takes place in a world where people can choose how they will be reincarnated. The protagonist, referred to simply as “Me”, encounters a somewhat cold and sarcastic goddess responsible for managing reincarnation.
When informed that popular reincarnation options come with extremely long waiting times, the protagonist makes an outrageous and unexpected request:
To be reincarnated as “the rib of an overpowered hero” who enjoys a harem and a perfect life.
This bizarre premise sets the tone for a comedic yet thought-provoking adventure, exploring identity, purpose, and unconventional choices.
