Sword Oratoria gives great development of the world from Ais Wallenstein and Loki Familia perspective.
Unlike s1 where it's just Bell's adventure, here plot revolves around Loki Familia and their story. We get much deeper into the inter-god politics, we see how Bell is seen by others and what his place is from another point of view.

Pretty different from s1 less comedy and much less fanservice. Quite serious season packed with even more stunning incantations, spells and battles.

It is not only extension of s1 but also kinda prologue for s2 (or at least feels like that, idk cause haven't watched it yet). A lot of brand new characters, and more information about these who already appeared.

I'm honestly surprised how smoothly and well fitted it is into s1 plot. It perfectly fills the gaps and answers unanswered till now questions 'bout s1.
It all kinda feels like it could be just merged into one and would be a story with 2 protagonist (or just two points of view)

Now I'm ultra hyped for s2. I recommend 10/10 for everyone who already watched liked s1 of Danmachi.
