Update (6-12-25): I added a version that combines both the original, PoRO art style and the Battle - Revolution style. This is a very intricate dataset with over 900 images! I'd say it looks closer to Revolution, but it still provides a unique art style compared to the other two.
Update (6-7-25): I added a version based on Nuki Doki! Tenshi to Akuma no Sakusei Battle - Revolution; I've updated the description and heading to accommodate this.
A commission! The initial commissioned model is based on the two episodes of the 2013 OVA Studio PoRO did. The commission was initially for Firika, but I included Sera as well because why not? However, I was later provided a complete dataset of Nuki Doki! Tenshi to Akuma no Sakusei Battle - Revolution, i.e., the (rather goofy) episodes Collaboration Works did.
Note: Due to her very brief screentime in the 2013 version, Nonoa Momose will be extremely hit-or-miss in the PoRO version; I did, though, attempt to include her in the dataset. She has a lot more screen time in the 2016 version by Collaboration Works, so that model will be preferable if you want to make images of her.
