Ok, so maybe I'm going a little bit overboard giving this manga straight 10s but it was, in my opinion, one of the best Higurashi mangas I've read.
Story - What can I say? Absolutely fantastic! It follows the plotline where everyone dies in the 'gas leak' and is set 20 years later with new characters and an older woman - Sonosaki Mion. The story itself was a mini mystery, trying to discover who was the murder and with Mion being suspicious through the whole story till the very end.
Art - As always, very beautiful. There were scenes where you see the ghosts of Rena, Keiichi, etc which was beautifully drawn and was very nostalgic.
Character - Mion has always been one of my favourite characters and this story explores a bit more into the politics of the Sonosaki estate. Otobe is the new protagonist and is mistaken for Satoshi a lot, he is a very likeable character and makes a nice change from the usual rabble.
Enjoyment - I really enjoyed this manga and felt that it showed the events past the gas leak and deaths of our favourite characters very well and has a lovely twist at the end of the manga. It also has some interesting more supernatural aspects to it.
Overall - A MUST READ :D
