1. Story

The main character: Rachel Gardner is being trapped in a building. On each floor there is a story and a puzzle to solve. Each "mastermind" of the floor will try stopping Rachel from going up to the next floor. The battle betweeen the "mastermind" and Rachel always end up being bloody. The whole story ends up in a cliffhanger.

I think the concept is very interesting. We can learn about each floors background as well as Rachels information. Since she lost her memories about her past, she tries to find more about what is going on. After she passed the first floor, she gains her first companion, Isaac Foster.

Without Isaac, Rachel is only a poor girl which cannot fight on her own but she uses her brain to get up the floors. At first I thought, Rachel is just someone who ended up in the building as an outsider. But as the story continued, it was clear that she actually belongs to the building herself. Why she ended up on the first floor and why she lost her memory is very blurry. The story could be much more detailed about that.

2. Characters

Rachel Gardner: a cute and innocent girl (first setting). Her blue eyes always look so dead and she doesn't really care about her life. She wants to die by Isaac Fosters hands and tries to get through the floors to find the way out.

Isaac Foster: the man with the scythe. He reminds me of a grim reaper. His face and body is covered with bandages. I think that fact could be explained more deeper why he actually has that appearience. Isaac doesn't really use his brain and smashes everything with his raw strength. That is why he accepted Rachels request in killing her when she finds the way out of the building.

Side characters: There are many side characters which I call "masterminds" since they all own a floor. I'm a little bit disappointed that many characters didn't have that much screen time and their background story weren't really explained. It would be more interesting to know what actually happened to them too. That would have helped to get a rough situation of the building.

3. Soundtrack

Persoanlly, I think the sounds were actually pretty decent. Sometimes it was a bit loud which could be explained by the fact that the characters are using guns. The soundactors were choosen well. My favorite one is probably the voice from Isaac. For the Openings/Endings I liked the Ending song the most.

4. Art / Animation

I like the art of this anime. Isaacs Character looks very nice with the bandages and the scyth. I personally love scyth on characters. Rachel is a bit easier to draw I think. She is drew not as detailed as Isaac which makes her a bit bland. The art of the different floors could have been improved a bit, but all in all I have nothing bad to say.

5. Conclusion

The title of the anime "Angels of death" is a bit irritating for the story. They tried to put a puzzle in a horror adventure which is very interesting and fun to watch. For the puzzle part, it is more fun to actually play the game instead of watching the anime. Story and Characters could have been more detailed and the ending was a bit weird too. We don't know what actually happened since Isaac is supposed to have died, so Rachel killed herself in the end?
This is why I give the anime a 6/10 since I liked the art and the concept. They lost 4 points for the undetailed parts of the story and characters. Worth watching if you have free time
