Kekkai Sensen!

I like to compare this show to a stereotypical American. It literally does whatever the fuck it wants.

This show is pretty outrageous with its everything. Its story is just completely out of this world, and in my honest opinion, it's pretty hard to follow. I don't mean that in a "it's incredibly thought provoking" way, I mean't that in a "basically nothing makes sense" kind of way. Read the Disqus comment section of each Kekkai Sensen episode on Kissanime, and you'll see countless comments asking "what the fuck happened?"

While the overall story line itself is fairly lackluster and a chore to follow, Kekkai Sensen ...

So here's an anime that I thoroughly enjoy. First review so... let the hate come. Also, this is a review for the 6 episodes I have seen, so I'll only go over what I know from those episodes only.


Story

The story of Kekkai Sensen (Blood Blockade Battlefront) is a confusing one, especially considering that at the start of episode 1, we see Leo's sister with her eyes open. When later on, it's said that she is now blind. I guess it'll be revealed as the story goes on, but there really is no story.

All there really is, is just a bunch of random things that ...

Tenth Review - Kekkai Sensen! (or Blood Blockade Battlefront)

This was a anime that looked pretty good to begin with - a city that exists with human and monsters together. The story revolving around this one lad with these cool looking eyes.

At first it looked more like a comedy rather than a serious anime yet the more you watched it and let the story unfold you see that this is actually a well structured anime that has serious elements but also bonds together with humour in some areas.

The story in my opinion at first was a bit rough round the edges and didn't take ...

If you're a big fan of Durarara!! you'll definitely enjoy Kekkai Sensen, both having seemingly random episodes focusing on random characters each turn.

I'll just say this: Kekkai Sensen was definitely one of my favorite anime of 2015, being more unique than others, and other reviewers seem to agree. Either you'll love it or hate it, since the tangled plot can annoy viewers. Without further ado, let's get to it!!

Story:5

I personally despised Durarara!!, the plot was boring and the story was bland to me, and Kekkai Sensen fits the same mold yet makes the story in a much more unique way as ...

Set in a fictional version of New York, where humans and bizarre monsters live together in not-quite harmony, Kekkai Sensen is one of the most successful shonen series of late. The show follows the adventures of Leonardo Watch, a kid with the gift of super-powered eyes, as he joins Libra, a quirky team of vigilantes who... protect the city… or stop crime… or something… let’s just say exposition is not this show's best suite.

If there is a thing that can be said about Kekkai Sensen is that it definitely starts with a bang. The first couple of episodes are nonsensical action-packed trips that have most ...

Spoiler free!
The concept of the world is really cool. I think the powers these characters have are really cool. The songs of both season one and two were good and so was the artstyle. But I just didn't enjoy it that much. I think mostly that is because of how we get a ton of charcters in the show, but none of them seem to have been worked out. Whenever something new is going to happen in the story, they add new characters that never come back in the show.

Overall I'd just say that the character development was very poor for this show. ...

For all the deserved and undeserved criticism it gets, Kekkai Sensen is, undeniably, one of the more unique shows to come out the past few years. And that is a good thing; a great breather from all the repeat-process shows coming out nowadays.

Kekkai Sensen is about a group called Libra, an underground society charged with protecting Alien-Infested New York + Some magic. Now, I don't know about you, but that sounds pretty cool.

But does it live up to its uniqueness? Its aforementioned criticism?

Story (4/10)
Kekkai Sensen is an episodic anime; meaning, 'villain of the week' or similar stories along those lines. Some people hate it, ...

"Kekkai Sensen" is a unique and enjoyable experience that succeeds through its non-conventional use of visuals.

For me, after I re-watch it, the show was still great.It’s smart, gives off a sense of uncontrollable energy and fun, action-packed and also builds in a surprising amount of heart and emotion.

As for the plot, it was amusing, the comedy is on point, the characters were entertaining, the show's structure was original.Despite the delay of the last episode, well... I have to say they did a great job wrapping things up, sticking with the same themes of the previous eleven episodes: life and love; friendship and belonging; teamwork and ...

I just finished this anime after 7-8 days, i don't want to write a novel here, also i won't spoiler anything so feel free to read:

The creativeness of the art of this anime is so well-done, i really got amazed in some episodes.
The Characters are greate, one of them is looking familiar to me (Steven A. Starphase) just in an older version (sorry, might sound cringe, but true).
Outro music is actually a good one, meawhile the openning and background music are part of the "meh" chategory, but the sound effects are again a thing they made well in this anime.

Now let's talk about why ...

This is my first time writing a review for an anime.

Kekkai Sensen was one of my favourite anime that I've watch so far.

Plot:
The plot was all the place but I was still able to tell what was going on. At times I did get confused and I still have some questions about this anime.

Probably one of my favorite shows from this year.If you ever watched Baccano and Durarara and liked them,then look no further cause this is your show.
Kekkai Sensen is the epitome of good,crazy and amazing stuff all mixed together with really cool characters.Let's start as always with the good things from this show.
-The art
Beautiful art,beautifully designed characters in a beautiful city that is called New York.But it's not the usual NYC,it's even cooler.Creatures from the other world are here too ,since the gate is breached here and it's called the Hellsalem's Lot now.Various stuff is going on in the city that never sleeps and it's a ...

I wasn't sure at first whether I should watch Kekkai Sensen, but I just gave it a try - and I did not regret it!

This series is wonderful, in my opinion. It really entertained me and motivated me to watch on.

The art is stunning, especially the environment and athmosphere.

The music used shows much variety: Cool and energetic background soundtracks, relaxing vocal pieces, even classical music! It is fantasic to see such a great range of different styles in one series.
The usage of the songs is also interesting, as they occasionally combined them with scenes that would typically not be thought to fit together with ...

New York City is overrun by monsters!
The statement itself seems quite quirky. However when put into context, it truly is just another day within the world of Kekkai Sensen. A world so vast, so mysterious, so telling, and downright awesome, that the depth of its possibility seems endless. That's, enough of my praise. Let's get down to business.
Story: 9
Kekkai Sensen introduces a very enticing, extraordinary, and complex story. It gives little detail upon where we are in our current situations. It leaves, gaps, holes, and mysteries to be solved. Not to mention the unbelievably fast pacing that the anime showcases. Despite the claim that all ...

This anime confused me to the core. It confused from the first episode and just when I was getting the hang of it, it confused me at the end as well. I had all these questions that I didn't know where to get all the answers from. For everyone's interests, I will keep this review SPOILER FREE.

All right... Let's take it from the start:

You can read the anime description to get a feel of it from the anime page, but I will tell you how I understood the plot. The anime takes place in another land, in a city called Hellsalem Lot. Formerly known ...

This is one of the most underrated shows I have ever seen. Usually when Bones does a show like this there are at least some fans or people that hype it up (Darker Than Black, Noragami, and Stray Dogs from this season) but I didn't even know this was a show until I saw it on Funimation's Dubbletalk, and even then I ignored it. However I am very glad I decided to give this show a chance.

First the story. A gate to an alternate dimension is opened in NYC devastating it and covering and fog. Large amounts of demons file out and inhabit the ...

I can say now with confidence that Studio Bones is the best animation studio in Japan. They have consistently created some of the greatest animated series to ever grace the anime industry. The resume of the studio is a storied one, ranging from Fullmetal Alchemist to Ouran Highschool Host Club to Darker than Black to so many other amazing shows. Yet amidst all of this, one anime was criminally underappreciated. 2015's Blood Blockade Battlefront, or Kekkai Sensen, is an explosive, beautiful, and at times hilarious romp through one of the coolest fictional takes on New York City I've ever seen. From Yasuhiro Nightow, the writer ...

Kekkai Sensen peaked my interest because of the soundtrack. And let me tell you, that was one of the best jazzy and blues-y OSTs I've ever heard. Additionally, I'd added soundtrack to the second season last year, not knowing that it was made for this show (yes, I'm gonna watch next season too).

I LOVED the friendship between Leo, Zapp and Zed. This was the best thing in the whole show tbh. Their dark bloody humour balancing the naive Leo's, arrogant Zapp's and straightforward Zed's natures. Nonetheless, other characters didn't catch my eye, sadly (as well, as the art - it wasn't something wauw).

Coming to the ...

Preliminary (8/12 eps)
This is probably the only anime that I have ever watched and enjoyed to the maximum with a confusing plot. In the end, you might asked yourself, 'why did this particular thing happened? What does it do to affect the plot?' A lot of unanswerable question yet the show is still fascinatingly interesting and wonderful.
With a likable Main Character that had the eye of the all seeing god, he was the center of the attention.
To all the fangirls out there, you might called the caring relationship between the people in the agency and Leonardo Bromance. Well, not technically, unless you started putting people ...

Okay, Kekkai Sensen. Let me just say that if you like your superpowered urban fantasy or Baccano and/or Durarara, you may like this series.

Story:7
The story revolves our main character, Leonard Watch who moves to Hellsalem's Lot a monster filled New York, in an effort to find out about the mysterious power he has been given. While this, at the start, is his main goal, I don't believe he finds out by the end of the season which makes sense as the anime is only a partial adaptation of a longer manga series. However, there is a larger, plot that goes on in the background of ...

BBB is like a beautiful painting. You can stare at it for hours, admire, be captivated, but at the end of the day like each painting it has frames and around a white wall. One thing I must say it’s a complete picture. As it stands the story is finished, we may be back someday in BBB world, but this part is over, and that’s a very good thing from anime perspective.

Art 10/10

Reference level. Probably one of the best, graphically made anime in year 2015. You want to scream, why my favorite anime doesn’t look that good?! Studio Bones just delivered everything you can ...
