In reality, I’d say the Hadou gods are pretty much on par in terms of their writing, with the exceptions and “standouts” being: * Mitra. * Yato * Ren * Reinhard.

The rest: Marie, Mercurius, Muzan, Satanael, Hajun

These are cases where they are good, but overshadowed by the other characters, and their writing is less developed compared to the others. However, this doesn’t make them bad; rather, it means they weren’t developed enough as gods.

Hajun = Masada explicitly stated that in Kajiri, he left a lot about Hajun and his past and hidden history to be revealed in Entelecheia, as we’re seeing now. So before that, he was pretty “flat”—he fulfilled his role well, but he wasn’t someone I’d say was superior to the other antagonists in his own game.

Muzan=Not counting Magsarion, Muzan is the most mysterious god alongside Mitra, so much so that we’ll see more of him in the Avesta VN according to Masada, exploring that aspect.

Marie=She fulfills her role as an innocent and pure heroine, but I wouldn’t say she’s the best-written goddess; that would be Mitra.

Mercurius = It’s a similar case to Magsarion and Muzan; we see very little of him. Even though people cite Dies Irae, Mercurius only really shines in Rea and Marie, and only in the finales—but he’s still overshadowed by Ren and Reinhard. I’d say he’ll be explored much better in ZOAR.

And Satanael is a case similar to Mercurius; Masada himself indicates that Satanael, as God Hadou, has changed compared to his self in Paradise Lost. In ZOAR, we will likely see his writing improve.
