So a horror of modern day Tokyo being invaded by man eating "Dragons"... I loved it up until they start trying to fight the dragons with crazy sci-fi powers and stuff. The Manga starts of strong, real survival horror feel and all. Many Many shots of people being eaten and generally horrifying depictions of dragons that are grinning while eating people. Honestly the dragons are the real stars of this manga their design is rather far from what a dragon traditionally looks and acts like, which is for the better lest it feel like an isekai. However near the mid point of what's translated to English, thesurvival element almost all but gets dropped and the character your following is suddenly in a military style training to fight the dragons with some scifi BS. You can tell they had an initial vision but no plot when this went into production.

Overall its an interesting once over and even though its been years since i read it, i still remember those damn grinning dragons eating people.
