Fallen Priestess My Sister’s Demonic Bloodline Review

Unlike the previous game Nebel where the dungeon exploration system was quite complex, this game features orthodox, symbol-encounter style RPG Maker dungeons. Yes, dungeon exploration is simple. But as always, everything else is complicated with this circle’s work.

First, the battle system. The protagonist uses an action point system, allowing them to act as many times as they want within one turn as long as they have points. You can check enemies’ actions in advance, and by reducing their posture value, you can cancel their turn for that round. This allows for considerable strategy, like “The guy on the right is charging a strong attack this turn, so I’ll lightly reduce his posture to defeat him next turn and use my remaining actions to blast away at the left enemy,” or “This turn I have room to breathe, so I’ll nicely reduce everyone’s action values,” or “The back-row enemy who’s out of reach for melee attacks is dangerous, so I’ll use an attack item to quickly take out the vanguard.” Moreover, since battles always consume MP, and the protagonist’s MP is also used to avoid NTR scenarios, you’re left balancing whether or not to engage in battle at all.

Next up is crafting. Items are set to be quite powerful, and you’ll want to actively use them to avoid NTR scenarios. However, there are limits on the materials you can gather. So you need to obtain insufficient materials through other methods – but efficient acquisition methods are something all eroge users know well, right? Yes. In exchange for your little sister enduring part-time work harassment and worse progressing NTR scenarios, you gain money and materials to create tools that prevent the worst outcomes.

The erotic system is considerably simpler than in Nebel. While you do need to collect items that bring out your sister’s desires (which can be sold at a high price), basically if you don’t supply MP from the protagonist, it will progress on its own. It’s twice as delicious with both pure love and succubus transformation!

In summary, this is a resource management RPG that narrowly runs along the boundary between conquering challenges and NTR scenarios. Pure love lies just beyond the edge.

of the Japanese review:

I had the pleasure of writing about “The Most Anticipated Human Work of the Year! The Ultimate Netorare Work Is Coming!!” (Currently, you can see it in all summary articles).
This work is a long-awaited netorare work from Circle BBQ’s “Nebel: The Lamb of the Beginning”.
The general content of the game is like this:
・ Although it’s a netorare work, the heroine tends to run wild and end up having sex.
・ The battle difficulty is high and you may feel confused at first.
・ There are also dot ero scenes in the ecchi scenes.

Since the circle is overseas, there are parts where Japanese feels a bit strange, but it’s not a big deal. The battle is as unique as Nebel R, and if you don’t understand the battle specifications, even weak enemies become tough. Boss battles are even more difficult. There are many conditions for ecchi events, so you may be confused at first (There are ways to do it, though).
Anyway, even if you say you want to see ecchi quickly, this game isn’t one where you can do it right away. But high-difficulty erotic games give you a sense of accomplishment when you finally get into ecchi. This year’s erotic games are decided with this one!

I’m so embarrassed to admit it, but I really love NTR games, and I’ve been keeping an eye on this one since last year, right when it was first released. The cover had been burned into my memory for quite some time. However, I hadn’t been following the circle’s announcements at all, and I never tried out any of the demo versions they occasionally distributed. So, I just assumed that the character Trina was a typical tsundere brunette twin-tail little sister – a common trope. But when I actually played the game, I was blown away by what a perfect dere-dere imouto character she is! She’s absolutely my type. That’s why Prince’s NTR hit me so hard; it was heartbreaking, and yet, that was the most exciting part for me. I kept going back to it and fapping over and over again.

The way her hair color changes and she becomes more proactive also created an incredible gap that was just the best!!

Thanks to this game, I ended up playing all night and now I’m sleep-deprived lol.

I feel bad saying this based on my own subjective opinion, but with eroge, once you somewhat understand the content and fap to it, it’s over. Since I myself want to play various games, I’ve been trying to keep the playtime for these kinds of games short. But damn, there’s never been an eroge I’ve done this much to with my own hands! This is the first time I’ve fallen in love with a 2D character like this in a game.

Thank you for such an emotional experience. I really love Trina-chan and was inspired to write such a long review because of her. Now, I’m going to go watch some netorare and cry while fapping.
