I thoroughly enjoyed this and will gladly recommend it to anyone into philosophical situations, existentialism, as well as in a general manner, anything psychological. The romance is a nice touch and genuinely contributes to the story without feeling like it was cheesy.
If you've watched or know what
Death Parade is, read Lewis Carroll's works (Alice in Wonderland, particularly), read Nietzsche, Camus, Kafka, etc etc, as well as having liked it, this is
definitely a must-read. Oh, and I found this through the related "Alice on Border Road" franchise, which hopefully is just as good as this series.
The storytelling by Asou Haro is definitely the best I've seen in a long time and the structure of the manga ensures you're kept on the edge of your seat and not bored. My only complaint, if any, is in all honesty, meek in comparison to how good this manga is and I ended up being satisfied by it anyway - the ending. Definitely needed one last panel of a certain character/two certain characters together though
