Use the clues that appeared in the Problem Edition to solve the mysterious case.
If you like logic puzzles and detective stories, give it a shot!

The game is divided into "Problem" and "Solve" episodes. In Japan,
the "Solve" episode was preceded by a massive "Guess Who" session, in which over 1,000 people participated.
Solving the mystery with "special rules" involving zombies, vampires, and other monsters has been highly praised by experts in authentic mystery.

Also, the cute looking characters and the fantasy elements surrounding the vampires are very popular!
This is an authentic mystery-solving game that can be enjoyed by both children and adults.

STORY


Arne Neuntöte is a vampire detective who manipulates supernatural powers.
Lynn Reinweiß is a nobleman’s daughter who loves vampires.

Their worlds should never have crossed, but they join hands to solve a bloody mystery.

In the darkest of nights, Lynn finds herself in desperate need of help.
Then she wanders into the mysterious city of "Lügenberg", where non-humans live.

Lynn's world changes drastically when she encounters "Arne", a vampire who is called "the worst" in the city.

And tonight, a new "murder case" has occurred.
What is the truth behind the bizarre incidents that take place in a world where humanity and the bizarre intersect?

"Come on, human. You may dance merrily under the crimson moon.”

I bought and played this game (roughly $12 bundling the base game + DLC) in preparation for the anime, currently airing at the time of writing. In relation to the anime, the entirety of this "Case 1" is adapted in episodes 2-5, with seemingly all other episodes being anime-original. Sadly, it seems that the Interlude DLC was glossed over. The game itself was a fun little murder mystery. Classic set-up: a murder among the family and staff at a noble mansion. And here, the detective that steals the show is a vampire. And the heiress who hired him is a vampire-fanatic. The story was fairly satisfying, funny, and left opened-ended plotlines for further installments, which eventually may or may not include what is currently airing in the anime. I didn't find the gameplay perfect... it's one of those games that has no achievements, and you can't screenshot purely by your hotkey. Other than linearly playing through the story, which isn't punishing at all, the only extra content you can really explore is to play through different deduction & mini-game segments with Lynn PERFECTLY to unlock a couple of extra non-sense fluff scenes after the credits. So don't be like me and actually make …

It is a delightful game that almost plays like a show(with the intro and recap and such). I do hope the developers will continue expanding on the story as I would like to find out more about their backstories and these hearts. The game focuses on the death of the girl's father and who the killer is while adding some hints of darker things that went on. There are three episodes that are split into 'cases' that you can select from at the start. The music is very enjoyable and catchy and I did enjoy the humour that went along with this. The personality of the characters work very well, especially the dynamic between Lynn and Arne. It does not feel like the characters have to compromise, they are who they are. The art is visually appealing and clean and there is a lot of expression with their pixel forms too. The little extras were not expected but very much appreciated. It felt like the developers were experimenting with the limits of RPG Maker by adding all sorts of minigames to keep it entertaining and refreshing. I also appreciated that it does not matter if you make a mistake as you can still play through the story but you are rewarded if you make no mistakes with some extra g…

Ive played a lot of RPG maker games and this one was def a gem, but is slightly different than other popular ones like IB or the witches house. The case book of arne is more so a visual novel with some small minigame segments so if you dislike lots of reading instead of exploring, this isnt for you. 10/10 mystery 10/10 vampire

Fun game that has a nice edge and doesn't take itself too seriously. A short enough romp. I need case 2 translated immediately please.
