Shinmai Maou no Testament: Toujou Basara no Hard Sweet na Nichijou

I find it hilarious how the best episode is literally a hentai episode.
For once, they got rid of all that generic demon plot bullshit mixed with unnecessary drama and focused on the slice-of-life aspect the series attempted to have. Because of that, this episode was much more enjoyable than I had anticipated. For once, there was consensual sexual tension instead of being enslaved by jealousy or the idea of betrayal.
This OVA also focused on Maria, which is good because she's the show's lifeblood; without her, this anime would fall into obscurity.

Lastly, if you're going to watch this series, I'd suggest watching this episode ... as it's the least cringe-worthy of them all which is saying A LOT.
Sadly, you'll have to watch the previous series for context purposes. Good luck with that.

There is no plot in this one since it's just an OVA. So the whole point is for the ecchi/erotic scene to be honest.

The first part is the same generic ecchi slapstick, not worth mention because it's just the same daily interaction with the MC and the main heroines.

The best part is gotta be the second half, the school teacher. That scene alone carries this whole series/franchise, the voice acting is also very good, 11/10 would watch it again ( ͡° ͜ʖ ͡°).

That's all in it, I can't elaborate more but I had to write something to fill up the quota for this review lol.

If you're looking for more fan service to add to the already overly-fan-service laden Testament, look no further than this episode. It's packed with ecchi in various forms whether it is Mio's perverted dreams, more of Maria's mischievous acts, or the school nurse getting in some action with our protagonist. Though definitely a side episode, the last portion does give a bit of insight and character development to our busty nurse.

Animation:
The animation is on par with the main show; expect lots of ecchi and lots of nudity and lots of groping. There's no action in this episode, just a lot of ecchi scenes- if you've ... made it through the main show nothing here will really faze you.

Sound:
This uses the same OP and ED as the main show, and recycles the BGM as well. Expect the same good performance from the VAs as well, including lots of ecchi groans.

Story:
What I said in the intro pretty much sums up the episode. The first half is ecchi with the harem members. The second half is ecchi with the school nurse. Entertaining if you like ecchi or ecchi-based comedy but otherwise this can be skipped.

Character:
Given the short length, I wasn't expecting much in terms of development. Surprisingly, the show teases that the nurse might have more to do with Basara than what was hinted at in the main show, you'll have to watch it to find out more!

Value:
For half an hour's worth of ecchi, it's rather packed with... ecchi. If you want to test your neighbors, play this at full volume. It's not in any way necessary from a plot perspective, just a fun addition for fans of the show.
