It's another TV hentai and it's sort of okay, but the porn hurts the storytelling. Each episode only lasts six minutes, after all, and our heroine's got to get jiggy with the prince in every episode. Basically, we end up with:
(a) the unfolding relationship of Diana and Prince Sirius, which isn't too bad.
(b) a plot, which progresses in hiccups just before the end of each episode. They're only little scenes. You can't do much in that and they don't even manage to complete their own story. What's going on with Chris, then? She's been displaced by Diana, but she gets pushed back onstage at the end of ep.6. Where does she go? What happens to her? Do the showrunners plan to complete her story in a second season?
Anyway, it's another anime about a heroine who dies and gets reincarnated as the villainess of her favourite otome romantic game! Imagine a hentai version of My Next Life as a Villainess: All Routes Lead to Doom!, I'm In Love With the Villainess, I'm the Villainess, So I'm Taming the Final Boss, etc.
The protagonist (villainess? heroine?) is called Diana and her rival (game heroine but anime nonentity) is called Chris. Diana knows that Prince Sirius is supposed to love Chris, but also that the game has a bad ending that will lead to the world's destruction. Or something. So she seduces him. Or vice-versa. Either the show's inconsistent, or I missed something because my episodes didn't have English subtitles. Prince Sirius seemed to be doing all the running as far as I could see. Diana mostly just enjoys getting molested by him and has some slightly off reactions when he'd been hoping she might be feeling a bit more romantic. I quite liked their unfolding relationship, which has some interesting touches. (No, not like that.)
There's also, though, some other bloke at the palace who means trouble. Diana gets thrown in a dungeon. People have secrets, including her. (Wouldn't it be funnier if one of these "villainess game heroine" shows had a protagonist who didn't know everything in advance and could be surprised by basic backstory?)
Is this a good show? In the uncensored version, not really. A cut-down TV broadcast version (which exists but I haven't watched it) would have better pacing since it wouldn't stop the plot for sex once an episode, but equally I can't imagine trying to tell the Diana-Sirius relationship with no sex scenes at all. That would feel just as clumsy, in its own way. I quite like the ideas behind this series, but it's too abrupt, inconsistent and stop-start to make much of them.
