Review to Nuki Doki! Tenshi to Akuma no Sakusei Battle - Revolution: Plot: Firika harasses Yamato with her busty childhood friend, Nonoa. Then, scenes become very random. Tags: *Demon/Angel (9/10) *Big Boobs (8/10) *Mind Control (7/10) *Blowjob (7/10) *Public Sex (7/10)*Masturbation (Cumshot mouth 7/10)
*Schoolgirl (5/10)
*Ahegao (6/10)
*Comedy (Silly humor, 1/10)
*Yuri (5/10)
*Gangbang (6/10)

Good Points:
- Great character design!
- The animation is very good!
- Firika's scene gangbang!

Bad Points:
- NO SCENE HENTAI! (Until episode 3...)
- If you liked too much the previous Hentai, you will be very disappointed with this new adaptation.
- Comedy sucks.
- For some reason Firika and Nonoa are attracted.... sexually.
- A very simple plot compared to Nuki Doki! Tenshi to Akuma no Sakusei Battle. Besides which have short duration of 17 minutes.

Sound/Seiyuus:
There was a remarkable change: Aoba Ringo replaced Ayabe Yuika as Firika's voice. In this OVA she sounds more sadistic and serious compared to the tsundere and even tender voice that she had in the previous Anime Hentai.

Character:
*Yamato: Pervert with glasses.
*Firika: Demon, sexy and big boobs!
*Nonoa: Friend of Yamato's childhood. Busty and tsundere.
*Sera: Angel, silly and busty

To see Firika again in a new OVA was very pleasant, the rest I do not care so much. Obviously this anime doesn't compare at all to the 2013 adaptation of PoRO. This new version is acceptable only for the outstanding animation and character design. The story is a joke, nothing relevant and important. It's not a continuation of the first anime, you could say it's a spin-off and without any Hentai scene until episode 03.

Collaboration Works recently also premiered "Menhera Ayuri no Yamanai Onedari: Headphone wa Hazusenai" which also presents very simple scenes Hentai. I hope they make new adaptations much better than these and not lean to the "easy". I give 5/10
