This is a tale of stars, swords, and the Saintess. A town girl is one day chosen by the guidance of the stars to be the Saintess. Leaving her small town, her life in the royal palace begins. As she struggles with her unfamiliar duties, the one who supported her was a clumsy yet kind ice prince──
...Playing the generic fantasy otome game "STELLA: REGALIA" (Stel-Rega) was Guest's daily routine. But one day, in classic trope fashion, Guest was hit by a truck and lost consciousness.
When Guest woke up, there was an unfamiliar ceiling—no, a ceiling and a room seen thousands of times in the game's backgrounds.
Panicked, Guest rushed to look in the mirror.
Reflected there was the villain, the one who stands in the heroine's way and eventually meets a tragic end... yet remains popular among fans for the beauty of their conviction.
"So this is a villain reincarnation story..."
Just as that thought crossed Guest's mind like it was someone else's problem.
A black cat, the villain's familiar, came leaping in.
"Who the hell are you!? That's MY body! Give it back!"

Her motto is "just give it a try," which often drags Beo along. Supposedly the heroine, but she's so busy with her Saintess duties she has no time for romance...??
Yes! I'll do my best! Cleaning, laundry, cooking, anything! ...Eh? That has nothing to do with being a Saintess?

Intro
『STELLA: REGALIA』
A classic fantasy otome game of stars, swords, and the Saintess, where a town girl chosen by the stars falls in love with an ice prince she meets at the royal palace.
As an ordinary person and a fan of that game, you were struck by a truck that came barreling toward you like a total cliché.
When you next wake up, you see an unfamiliar ceiling—no, a ceiling and a room that are all too familiar.
It was the villain's bedroom seen in the game's backgrounds.
Thinking it couldn't be, you look into the mirror, and reflected there is that villain who stands in the heroine's way and eventually meets a tragic end.
"So this is a villain reincarnation story..."
Just as you thought that, feeling like it was someone else's problem...
W-Why am I in Nero's body...!? Is this a dream? Am I still dreaming...!?
