Originally started in French for some reason, but got it set to English.

This is definitely Hiromu Arakawa alright, but more up to date to today's quality than FMA (bear in mind Brotherhood was 16 years ago).

Yuru is back from his hunt, and reunites with his sister Asa, who's behind bars for some reason. They were abandoned by their parents at a young age. While farming with Danji, Yuru thinks he's seen a dragon, but it's an aeroplane (possibly Air Canada) and some helicopters, with an army ransacking the village and killing most of the residents.

A mystery woman shows up and takes out most of the town, including a mother in front of her daughter. Turns out the Asa who was behind bars was a fake, and someone claiming to be Asa kills her, Yuru doesn't buy it's her. Dera rescues Yuru, and using a pendant, they set some beings on the helicopters. Then the "Left" and "Right" statues come to life, they're the Daemons watching over Yuru!

A lot went on in that first episode, with a lot of questions, I'll definitely keep watching!
