You can't separate war from tragedy, where one goes the other is sure to follow. That is the theme of Pumpkin Scissors.
Note: Im a fan of war mangas like Groundless, Gunka no Baltzar and Alderamin in the Sky (all of which are serious war manga) so I may have slight biases towards the genre.
It's 2020 and if you're thinking about reading this manga, I highly suggest you do. It has 23 volumes so far but imo, they've outdone themselves after each one (it just gets better the longer the series go). Don't even consider nozomiEX's review, it's extremely outdated (making a review after reading only 9+ out of 122 chapters). I have to admit though, the first few volumes and chapters were a little light. The series' plot haven't matured yet. Nonetheless, I think the first few chapters did an excellent job of setting up for the rest of the series. It starts of easy, which I strongly believe is a good way of introducing the key characters and the world setting that make the world of Pumpkin Scissors so interesting (sections 1, 2 and 3, the Kauplan researchers, the secret 9, etc.). Even though the first few chapters aren't very heavy (maybe with the exception of the 908HTT arc) they all have a good amount of action, decent dialogue and a tiny hint of that bittersweet goodness known as tragedy (an gentle experimental soldier with a fucked up brain and an even more fucked up past, an old soldier who can't move on from the war, a tank crew who turned to banditry just to survive, the sole survivor of an experimental unit all destined to die, etc.) Once you've read all the way up to chapter 20, you'd have learned of three things in particular:
- The Empire is a piece of shit who treats even its own people like trash.
- The main characters are badasses trying their hardest to help victims of the war (see 1).
- Tanks are the hottest technology out there.
So once you arrive Karousel arc, you've just hit the first of the major arcs. There are short stories between these major arcs that are all really good on their own (just too many for me to highlight). Each major arc has a theme:
Karousel arc focuses mostly on espionage, intelligence warfare, the effects of fearmongering and superior-subordinate relationships (romance tag wasn't a joke, btw).
The following arc isn't that big on war but damn I think it was good character development for Randel Orland. You get to know the MC better, his history, his reasons for joining the army and just how lovable/awesome his character actually is.
Then your next stop is the Anti-Ares Terrorist arc and you've reached the best arc in the series so far, hands down the best arc in any war manga I've ever read. So much good detail, character development and serious discussion goes into this arc that I'm not even gonna spoil it with a summary. It's over 40+ chapters long, a third of the entire series, including the build up to it. I'll bet everything I have that you'll get super into the series after reaching this arc. It's like reading a fucking documentary on terrorism (ISIS, start taking notes).
Overall, it's a 10/10. Because although the Pumpkin Scissors tag include ones like Comedy/Action/Drama/Romance (and it does have a decent a amount of them all), it's a war manga before it is anything else. And that's why it a goddamn mastah-piece..
