Black Bullet Series Review



In the near future a virus called Gastrea that can turn humans into monsters has broken out. Highly contagious, and very feared, war breaks out but very few survive. Those who do, live in regions surrounded by massive monoliths made of a material called Varanium which repels/hurts the Gastrea. To fight the gastrea, partners made up of a promoter (human) and an initator (one of the female cursed children who contain the Gastrea virus but have a slow rate of infection) fight as civil servants to defend the growing threat to what remains of Tokyo.

Review – This one is going to be spoiler heavy:

I watched Black Bullet once, a few years ago (probably just after it finished airing or sometime around then) and I remember not having liked it very much. Recently I stumbled upon this series on Crunchyroll and tried to remember what my problem with the series was and I drew a blank. Actually, I drew a blank on more or less everything to do with this anime other than the fact that the title didn’t really make a lot of sense. Sure, main character Rentarou does use a gun occasionally, and yes, his bullets are made of varanium which is black, but as he tends to punch or kick things as often as shoot them and the gun has no significance to the story, I’m still totally lost on why the show is called Black Bullet.

Yes, he is a villain. Can’t you tell?

What I realised while rewatching this was that sitting underneath all the things that either annoyed me or made me feel a little disconnected from the events, is actually a pretty intense story full of rich emotion and great (if slightly obvious) questions about humanity as a whole. Unfortunately, the anime seems determined to help you overlook all of its positives in exchange for the generic and the lame and the balance between the two isn’t great.

Kisara is the best character to exemplify what I mean by this. Going heavily into spoiler territory.


For most of the series I was wondering why Kisara even existed (having forgotten how the story ended her character seemed entirely superfluous and mostly I’d written her off as the character who would probably die right before the final battle – I know now why that wouldn’t have worked but possibly the story should have done a bit more with her earlier). Anyway, Kisara’s role is completely ill-defined and as a result she’s either absent for extended periods early on (to the point where you forget who se is) or she’s shifting into whichever anime trope they’d currently like her to portray.

Basically, she’s Rentarou’s boss. Though other than one scene early on where she’s telling him off and another later on where she essentially orders him to let her work underneath him (that makes sense) you almost always forget that she ‘runs’ the company. Mostly because the company makes no sense. Why do civil servants need a private company when essentially they get hired more or less directly by the leader of the city anyway? Cut out of the middle man, or lady, so to speak and nothing would have changed.

And it is this absence of any meaningful role that hurts Kisara. As the story goes on you learn that she feel indebted to Rentarou because when her parents died he was horribly injured… tragic back story, childhood promises, angsty teens, got it.

At one point the story sends an assassin after her, because why not? I’m guessing technically they did that because Rentarou was protecting the target but why not send the assassin after the actually civil servant rather than the civil servant’s boss? For a few moments, Kisara gets to show off her cool sword skills that we’ve seen her practice but never use and then somehow, right before Rentarou shows up, she gets to fall and become helpless. Then, a few moments later, she gets to ‘save’ Rentarou before collapsing into his arms all frail and helpless again. Pick a side already. Are you strong and fiery or are you the damsel?

Another point in the series has both Kisara and Rentarou begin teaching at an open air school for the cursed children. They all fall in love for Rentarou (another issue with the show I’m going to get back to later) but Kisara mostly just stands at the front and occasionally interjects a comment. Her presence there would have been completely unmissed if they’d just not drawn her. When the school and all the students are blown up, Rentarou is the one who walks in on the police doing the clean up because Kisara slept in. Rentarou is the one who identifies the bodies and mourns at the hospital before having to deal with Enju (his partner and also a cursed child) as she discovers what has happened and mourns. All Kisara does is wait for him to come back. She taught at the school too, so why doesn’t she get any of these moments?

By the time we get to the end, there’s so many other things happening that Kisara becomes a point that you just kind of toss to the side, which is kind of a mistake given where they take her character in the final episode. If Kisara had been introduced in episode 8 or 9 (as a lot of other characters were) and had taken that character arc to episode 13, it could have been brilliant. From trained fighter but inexperienced in actual combat and starting out with a new partner under someone uncertain of his own command, heart burning with revenge for a previous wrong that was linked to the current wrong, to the character who coldly executes her revenge without another thought and clearly understands that she’s drawn a line between herself and Rentarou, it is an excellent character arc. But you don’t get to enjoy that arc because of all the other rubbish that this character has been put through prior to them using her for anything of value.

Spoilers continuing.


As I said before that extended ramble, it kind of exemplifies everything I loved and found problematic with this show in one character. Black Bullet has some truly heart wrenching moments and some really interesting moral conundrums to throw at the characters and the audience. It has moments of poignancy that just hit home hard. The final scene with Enju and Rentarou on the train where Rentarou finally lets everything that has happened over the past few days hit him and he breaks down weeping, head buried in Enju’s lap, is the perfect final note for these two characters after everything they’ve gone through. When the show plays the drama and emotion of the scene it gets it right and it does this enough throughout the series that you can’t just dismiss this as frivolous. Yet, it can’t commit to those moments either.

Rentarou could have been a truly interesting protagonist but he is plagued by the every single cursed child falling in love with him syndrome and self-aware harem and pervert jokes being thrown at him by all of the older women in his life (boss, patron, doctor who saved his life and now… hangs around). The relationship Rentarou is forging throughout the series with Enju is touching and heartwarming but when he plays the same big brother character to Tina and the blind girl and everyone else and they just sign up for the ‘I love Rentarou’ club it kind of buries some of the better Enju and Rentarou moments.


Enju’s insistence that Rentarou is going to marry her isn’t as irritating as it might be in other shows where an overpowered little sister character makes such a declaration. In this, it is heart breaking. You know Enju doesn’t have the time and any dreams she has of growing up are just that, dreams. They will never be fulfilled so Rentarou has no need to puncture that ideal of hers, but you can see it twists a knife into his heart every time she says it.

There’s a moment fairly early in the series where Enju has been to the doctor and they’ve checked her ‘corrosion’ level. Essentially once it hits 50% Enju is going to be killed because otherwise she’s going to turn into a Gastrea. Rentarou lies to her and tells Enju her level is somewhere in the 20’s when in fact she’s in the 40’s. Enju’s time is really close. That’s dramatic and you can see the look on Rentarou’s face as he lies and then in case you didn’t get it, he looks deliberately at the charm she gave him which was meant to break if he didn’t tell the truth and he’s removed it prior to speaking to her. It’s a great moment. That never, ever gets revisited. Enju’s corrosion level never comes up again in the entire series.


One final issue I had with this before I get on with recommending why you should watch this show anyway despite the fact that I did just spoil most of it, and that is Takuto. I get that in all of these types of stories there’s that one idiot who is out for his own agenda and has it in for the ‘hero’ to the point where he’ll do something stupid. But there’s a time and a place for stupidity. This guy takes it to a new extreme and what really bothers me about this is he doesn’t do it alone. A whole group of soldiers help him sabotage the only line of defence the city has in that final battle. What were they thinking? Even if someone successfully argued that Takuto was just mental, what about the others who contributed to this scheme? If the line falls, all of you are going to die. Did that not somehow sink in? Anyway, Takuto gets the award for an act that is just too stupid for words and that is in a series where one of the earlier antagonists ends up just joining in the final battle because, why not.


So, yes, Black Bullet has its issues (not the least of which is a title that keeps making me type Black Butler and then having to correct). There’s a ridiculous harem set up, there’s overly cutesy moments thrown in to what is otherwise a fairly grim tale, there’s boob grabs, and totally unnecessary rivalries, and there’s some obviously stupid decision making along the way. Countering all of that though are some truly touching moments, some scenes that know exactly what they are doing, a lot of moral gray areas for our characters to walk, and fight sequences that are pretty good. There’s also a lot of violence and gushy purple/blue liquid usually stained by blood.

There’s no problem when a show tries to mix drama and comedy. Many shows manage to successfully add levity to fairly heavy plots in order to not depress the audience entirely. The issue with this show is it never finds the right balance and you are never quite sure if this was ever supposed to be a serious drama (though the ending kind of leaves no room for doubt that this situation was dark and the cost of survival is high). But that means that for a lot of the run time you are switching between cute girls doing cute things, cute girls killing things, two teenagers out for revenge/justice/money, a whole bunch of other characters with similarly ill-defined motives, and then some monster bug things thrown in just to stir things up. All and all, it is just a little bit messy.


For my second watch I had a lot of fun with this though I honestly don’t see me going for a third watch. Providing of course I remember it this time.

  1. I agree that solid premise and missed potential describes this series. It does a bunch of things well but it’s negatives really hurt the show. I especially was disappointed with the ending episode which just left more questions than answers. As others have commented, the opening theme is awesome though.

    1. I’m going to be honest, I don’t even remember the opening theme. That doesn’t mean it was bad, but like much of this show it didn’t really stick after watching.

  2. I remember that the very first time I watched it, I really liked it but I always felt that it really lacked a lot of important elements. I’ve heard the light novels the anime’s based off of answer a lot of the questions the anime never gets around to, so I may have to pick it up. Thanks for this awesome review! I agree with just about everything you said, from what I can remember anyway. 🙂 Although I wonder how I’d feel in a second watch through. May have to give it a shot and see what happens.

    1. Being able to remember this series is apparently a serious issue for a few of us. That’s probably going to end up being the greatest criticism of the show. It does not make you remember it after that final episode.

  3. Just checked if this is available here, and it is. After reading the premise you have decribed for it, it definitely sounds like my cup of tea. Will get back to this review later, since it contains spoilers as you mention. Am almost done with Yuri on Ice and another anime series that I wish I had not watched (Hundred), so this might be up next together with the other recommendation from last week 😊

    1. This one has a lot of porblems but is kind of fun.
      I never made it to the end of Hundred. I probably should give that one another go at some point and see if I can finish it.

      1. Hmm….well…I can say pretty much one thing about that: I really wouldn’t bother with Hundred. Even though the series had some pretty cool concepts, it is pretty much ruined by bad jokes and pretty lame boobjokes that seem to have to be included in every single episode of this series. Shane really, because the series truly had some interesting ideas. Oh well, can’t win them all I guess 😊

        1. That’s probably why I dropped it the first time and didn’t continue with it. Still, I do try to give all anime a second go at some point. Some times I was just in a bad mood when I decide to cut them off and I miss things that might otherwise be good. Sounds like Hundred wasn’t one of them, but I’ll still give it another go at some point.

          1. That’s what I usually do as well. No matter what it is, be it anime, tv series or a movie, everyone experiences it differently, so I usually always form an opinion on it myself. Despite what a review might tell you. Hundred really has some interesting things going for it, but pretty much ruins it, because of all those completely unnecessary boobjokes 🙁

  4. Ouch, bringing the smack down on poor Takuto–I’m right here ya know! >.<

    But seriously, similar thoughts on the series. I already don't remember most of it. The world seemed pretty cool to me, as in the whole situation with the walls. And I recall Rentarou being a pretty neat guy. Other than those two things, I think the show was just too divided in attention: it was trying to show that the giant bug things were bad, but then the little red eye did girls were outcasts, too? Uf, could've been really good. At least Fripside's OP was killer!

    1. It is an incredibly forgettable anime after viewing and yet while watching there are some great moments. It’s all just kind of a shame and wasted potential.

  5. I’m pretty much on the same page as you on this. Black Bullet is one of those series that I feel like I need to go and buy the light novel for as I bet the story actually being displayed here is actually halfway decent, but the portrayal of it in the anime was absolutely horrid. Lots of unnecessary stuff, like you said, and it just felt like it was kind of a mess all around. That said, I still think the story they were going for was interesting, but the rest of the junk tossed in bothered me. Wouldn’t be surprised if there was production issues as well.

    It’s definitely what I’d consider a “stupid fun” kind of series. I enjoy it on that sort of level.

    1. I definitely found it enjoyable this time round but possibly I’d love to see the same story done better. There’s a lot of interesting things that happen but so many things that just didn’t need to.

  6. Black Bullet was a fun ride for me. As for your confusion in the title, I think it refers to that endgame weapon Rentaro used in the last fight. I think he needed to shoot the big Gastrea invading the city with a black bullet made out of varanium – hence why it probably was titled Black Bullet. Or maybe because it sounded cool.

    This show pretty much opened my interest to the cases of child abuse or just children suffering in general – there’s a lot of stuff going on with that right now and I just thought, after watching this show, “You know? This is quite similar to what children in third world countries are facing right now and it is depressing to hear that such innocent individuals with no knowledge of the whys and hows of their circumstances.”

    Great read overall!
