Saishu Mirai Shoujo’s official website introduces their profile as below:
The “Final Future” is a virtual space where anything is possible. The four girls embrace their dreams and perform to reach the final future. The next generation realistic unit, Saishu Mirai Shoujo, develops lyrics that capture the raw words born from their hearts, such as the conflicts and anguish that arise in the process. The melodic soundtrack that makes you humming along and the sentimental words captivate the hearts of a generation.
“Uchuuteki MYSTERY” released digitally on April 6. Additionally, “Nantonaku” (“Somehow”), a slolo song by member Nagi Fujisaki is also featured as the ending theme for the anime, which is scheduled for digital release on April 13.

The TV anime adaptation of Yomu Mishima’s sci-fi comedy light novel series I’m the Evil Lord of an Intergalactic Empire! premiered in Japan on April 5, 2025. Crunchyroll is streaming the anime for members in North America, Central America, South America, Europe, Africa, Oceania, the Middle East, CIS, Indian subcontinent and Southeast Asia.
Crunchyroll describes the series as such:
After a life of honesty left him betrayed, Liam is reborn into a vast interstellar empire with one goal: be the galaxy’s worst evil lord. But no matter how hard he tries to be a tyrant, his “wicked” plans keep backfiring into peace, prosperity, and adoring fans. Galactic chaos, magic, and mecha await in this hilariously misconstructed tale of a villain who can’t help but to impress.
