*wink* yeah, I don't know is that a studio make EC into a anime. But I think noone. I think they can split up the episodes and seasons like this:
Option 1[]
The plot of the story according to the timeline. But with a little back and forth plot.
Lust, Gluttony, and Pride[]
The Lunacy of Duke Venomania[]
The first episode tells the Venomania Event according to what's in the novel.
The Potrait Glassred Drew and other harem[]
The second episode tells about Venomania's harem after being released from his magic. It will eventually follow the Maylis bloodline that leads to Banica Conchita.
Evil Food Eater Conchita and Drug of Gold[]
The third episode tells about Banica's life from her childhood until she ate herself.
Some episode about song in Lucifenia Trinity[]
There will probably be one to three episodes or so here. But we'll assume there are three episodes.
Twiright Prank[]
We'll assume this is the seventh episode. The story will follow Banica who meets the twins Riliane and Alexiel on the beach. It's the same with the Twiright Prank story.
From here it is also told how Riliane becomes the Daughter of Evil and Alexiel (Allen) becomes her servant.
The Daughter of Evil and The Servant of Evil[]
The story in this episode will be according to Clôture's novel.
Tree Maiden, The Daughter of White, and Regret Message[]
The story is the same as in The Daughter of Evil: Wiegenlied of Green.
Praeludium of Red[]
This still same as the novel.
Praefacio of Blue[]
Reach For The Star ~The Letter She Kept Waiting For~[]
This episode will tell about Riliane's life before death picks her up like in the song.
The total for this season is around 12 episodes or so. This is the same as anime in general.
Sloth, Envy, Greed, and Wrath[]
The Journey of Two Mages ~Great Wall and Watchman~[]
Tells about Elluka and Gumilia with wall guards in the song above.

The Tailor of Enbizaka[]
This episode will tell about Kayo just like in the novel.

The point of view changed to Allen who was reincarnated as Kokutan-Douji. He meets Rahab who takes him to Enbizaka and the story continues to the next episode.

Kokutan-Douji meet with Gakusha (?) or whatever his name. Point of views change again to MA.
