Where to begin with this one...? Oh my, oh my.
I'll keep this one concise then.
Tsunpuri is a fairly straightforward Hentai Anime. Plot isn't much to write home about, but I guess the simple nature of it will probably be more appreciated by your right hand. If that's your preference.
The actual story demonstrated so far in the first episode is rather generic. Knight in shining armor and his, rather well endowed, Princess. He does his job well enough and, well, your brain can probably infer what it leads to. The genre paves the way for itself here. Now, there is potential for the series to
grow story-wise from here, but I'm not going to speculate here.
Now let's talk art. It's fantastic and reminiscent of the animation style of AIC Build and more specifically, the anime Haganai. Princess Reiana herself reminded me a lot of Sena in that respect.
The animation is very fluid and the colors are very warm and bright, which makes for a well-delivered Hentai in my book. The animation quality stands well and doesn't feel like it was done "lazily".
Now, talking dialog. Most of the actual speaking (In the episode so far) is done by the 2 ladies, the maid and the Princess. The maid character serves as a nice warm-up to the first episode and also takes up an expositional role. The Princess is more of the main focus, due to her closeness to our silent protagonist, the Knight. The dialog is not entirely boring and the voice actresses convey themselves quite well, making it interesting enough for me to not close the episode right away and move on. So it earns points there for me.
On top of that, the sex scenes were accompanied by great sound effects and the music was not bad either. I'm normally a picky H-anime viewer, but it definitely captivated sufficiently.
I can say I enjoyed this, and, let's be honest here, I did at least pop a decent stiffy during viewing, so my enjoyment quota definitely got filled in that respect.
I'd recommend keeping and eye out on this one for the next episode, but not expecting TOO much out of it in the end. It is a very simplistic anime, so if you're into that kind of thing, I recommend it wholeheartedly. If you'd like a more in-depth storyline, then perhaps not. It's always different strokes for different folks after all.
