太宰治の入社試験 is also in my plans for 2021 
I think it’s unfortunate that they already used material from it for the anime (season 1, episodes 6-7), but decided to rework it and put the plot in the future, with Atsushi already in ADA.
The fact that this is Dazai’s entrance exam and the first meeting of him and Kunikida is the whole fun here!
But I didn’t know it’s also written from Kunikida’s point of view. That’s something fresh and it’s making me even more excited!
