Great anime for Action + Adventure + Mystery. It had a slight hint of romance that is enjoyable. Would recommend
Story:
The continent is attacked every 300 years by a Demon God. On its first appearance, the Goddess appeared and vanquished the Demon God. But she said the demon is not yet dead, it will appear again. Upon its return, 6 heroes will come forth, bearing the Goddess mark and bestowed with her power.
Art:
The art is enjoyable, specially the fighting scenes.
Sound:
Liked the OP and ED songs. The BGM's are also good.
Character:
The character development is quite good, some of them are still vague, this should have a season 2 to cover all characters and continue with the story
Enjoyment:
The story is quite good and the characters are quite good also.
I really enjoyed watching; binged watch it for one day
Overall:
The only disappointment here is no news for season 2! I'm stuck with a cliffhanger of a final episode.
