Introduction

Kanna Seto is someone I knew I would be watching. She's obviously my kind of actress with her huge boobs but she's been taking the industry by storm. It's absurd just how dominant she has been, most popular debut I've seen since I started doing this. So naturally she made it to the top of the list and was the first debut I watched this year.



Physical

Facially I was only so-so on Kanna. Her short hair with that bang style isn't particularly for me. I think there's also something with her eyes that doesn't suit me, perhaps the light brown colour it has feeling so unnatural. I don't think she's unattractive but my initial thoughts are that her face isn't going to be the reason I watch her. At the same time there was a certain foxy quality with her eyes, like a deep longing she captured that was mesmerizing.

Kanna's boobs however were quite nice. 101J is a great size and easy to enjoy. They bounce and jiggle quite nicely and look like a great pair. I do find that her height seems to offset it a bit because at 170cm tall they don't seem nearly as big as you'd think, but don't mistake that for me thinking they are not nice. They were shaped well and came with some perfectly sized pink areolas.

Kanna's ass was a little underwhelming if I'm being honest. It seemed to be on the smaller side and didn't have much of a curve to it. Every now and then you'd see a glimmer of it being a bit curvy but really it felt like it wasn't the start of the show and wasn't supposed to be.



Performing

Kanna's hip movements were quite nice. Very reminiscent of actresses like Hibiki Otsuki where they can ride in cowgirl in such an excellent way.

Kanna's blowjobs also looked fairly nice with how much eye contact she maintained. She was just constantly looking up and making it feel so much more intimate as a result. Her paizuri was similarly good for the same reason, lots of eye contact during it. The technique wasn't quite as varied as I would have liked but that sucker was between her tits constantly. And really, it's that look in her eyes that really makes it all come together.

Kanna's performing in general felt a little too submissive to me. Maybe the video I watched had too much of a drama element or asked for her to be too submissive, but she was just moaning the whole time and not really as enthusiastic or engaged as I expected. The personality she exudes outside of porn makes it feel like she's two different people the same way that Rea Marumo felt. I think there were some glimmers where it seemed much more reasonable between her moaning not being super excessive and the good eye contact, but it wasn't consistent enough. What she did have was a good foxy look and longing in her eyes that's hard to replicate. You could sense there was more than just the moaning and felt like she was actually into it.



Video Review

View Spoiler

Kanna Seto plays a student who stars an illicit relationship with her teacher.

Sometimes I get a little swindled by videos like this. I think wow, a schoolgirl theme, that seems good. Yeah, not this one. I've really come to loathe these kind of videos where they just go to a love hotel and do their thing. It feels too much like a bland love hotel video than it does the hot teacher + student video it was meant to be. Sure, there's some content with her in her schoolgirl outfit or even a competitive swimsuit for whatever reason, but I just don't want to see constant love hotel sex. You can do better than that, like the sole classroom scene where she gave him a paizuri. It's not a colossal failure of a video but I expected more and this was certainly a let down.



Career

Kanna's career seems to be going well. While she hasn't quite got the repertoire of videos yet to back things up she still has time to do it. We're only now just barely getting videos that aren't super bland and even still the most you're getting is "Kanna is your girlfriend" or a paizuri themed video. She does also have two IV so far, and two for the same company in the first year is a little unusual. I think what stands out the most is how she's doing outside of porn. She seems to be at all the events and everyone wants a piece of her. She just seems to have a natural personality destined to be the IT girl. I'm not super concerned about her releases still being lame because that's what S1 does with debuts, and maybe only if next year started trending in the wrong direction would I start having some concern.

She also has her first VR which is a pretty simple theme but always a good sign.



Verdict

Rating - A

I will definitely watch them again.

I feel like part of my rating is me giving her a bit of a benefit of the doubt that she can and will do better. Kanna is, for better or worse, the most popular actress in the industry right now. We always knew the industry flocked to debuts but Kanna is on a level we haven't seen before. It's really quite astounding just how well she's doing and there's so much potential for her to keep growing like this. Let's also not forget that her boobs are quite nice, even if her tall figure seems to make them feel a little smaller than they actually are. I don't quite think she's the slam dunk S rank debut that most of the industry seems to think but perhaps in the right themes she'll shine and make me a believer. She has a few quirks to her that make her have some potential, and I'm definitely interested in watching again. I think she just has this way of looking at the guy that makes you wish you were there and I can totally get behind that long term. It's not going to be me watching the very next video, but I think there's a lot of room for videos that can shine and I'll be more than happy to watch one of them.



This year I am doing 31 debut reviews, one each day in December. Make sure to come back tomorrow to see the next one! If you want to see which actresses I've reviewed so far, check out my advent calendar post.

Recently a number of US states and a few countries of note have enacted age verification requirements for adult sites. On the US front at least, legal experts both within and outside of our industry do not believe any will pass a constitutional test. However, since these laws currently are on the books and thus have the ability to be enforced, we are choosing to comply with them at this point in time.


ZENRA uses Bluecheck.me, a third party verification service, to perform this important task easy to install filtering software does infinitely better.

Information used in the verification process is not stored on our servers. Phone number and address verification is instant and uses database cross referencing (no calls, no SMS messages, nothing mailed to the address). ID verification takes about one minute and is performed 'blind' on Bluecheck's side where the ID is reviewed by someone unaware of what service the submitter is attempting to access.


Regardless of what method you choose, it costs you nothing, but does increase the cost of our operations in order to somehow make the internet a 'safer' place.
