Nothing about Saitama passes the eyeball test when it comes to superheroes, from his lifeless expression to his bald head to his unimpressive physique. However, this average-looking guy has a not-so-average problem—he just can’t seem to find an opponent strong enough to take on!

To stop a Demon-level crisis, Saitama and company head toward the action. However, even Class S heroes prove to be no match for the Deep Sea King! In order to protect the good citizens, our heroes will need to summon all of their courage and confront this threat!

He is the Deep Sea King and he is here to stay, he is also to lethally kill every human being in the City! Only the Heroes can stop him, right? In a tortuously delightful run of battle scenes I got a solid look at a number of mentioned and new-to-me heroes as they give their all including the likes of Genos and Sonic. Is this threat big enough and deadly enough to enliven our hero Saitama? This just gets better and better, it might be a familiarisation with reality and/or humour, but ultimately it was the real effort to start world building around the Heroes Association. Really enjoying this one, 7 out of 12, Three Star read, but also the best volume so far.

Another really enjoyable volume in this series that finishes up the battle from the previous volume. This story is a bit repetitive at times, but I absolutely adore the characters. I’m looking forward to spending more time with these heroes soon.

Amazing how the volume gives us even more depth into a character that only seems like a conceptually disastrous hero. Saitama finds himself doing some more crazy things that other heroes (who legit LOOK more powerful) and yet his reasons to what he does still remains a question of fun. While reputation still is important to him, his pursuit of it continues to be impossible with the perception of the population being easily manipulated by others who are envious/skeptical of Saitama's greatness.

I still can't get over the beautiful artwork.

Yours truly,

Better than the previous chapter. This one made a little more sense to me.

The Deep Sea King is a proper villain in this volume. I loved seeing him kick the crap out of all these oh so heroic heroes. If it wasn't for Mr. Bald Cape, this would all be on the same level of drama as One-Piece. Good thing we have Mr. Bald Cape to inject a lot of interesting twists, no?

The pathos! The explosive-gut laughter! :)

An easy read and not too bad in the pricing department. The usual everyone struggles and then bam, the monster is gone with a single punch. Would’ve been interesting to see how Sonic fared with his gear. Saitama now rank B with more trouble to follow. So much nakedness in this one.

Great volume! Complete action. Continues on from the last volume with the Sea King villian. He wants to eat everybody and hero upon hero comes to take him on but he's too powerful, until finally One-Punch shows up. But when the people finally want to give One-Punch the credit he says they must give it to the others for all the effort they put into weakening him first. First time OP let's his arrogance down. Then finally he get's a letter with an upranking and a chance to move up into the next class. So while this volume is total battle action, One-Punch is developing character and finally making some friends.

THE. ART. 👏🏽👏🏽👏🏽 Yusuke Murata is a god.
Genos and Mumen Rider are the true stars of this volume along with Puri-Puri Prisoner (lol, I can’t with that one). Such good guys. And, of course, Saitama is just as OP as ever but his amazing character traits shine through his bored demeanor more and more with each volume. Overall, amazing series. 💯

Yayy!! Saitama helping to break that freaking meteorite! WHat?! But hell yes he is doing it! And guess what? He freaking punch through it!! WHat!!!!!!!!!!!!!!!! SOOO AMAZING!!!!!!!! Saitama looks cute when he land, LOL.

Also Saitama is now a freaking fifth rank in C-Class. I can't wait for the day when he becomes a top 10 S-Class!

I just hate tank top bastards!!! I hate them to hell!! For accusing Saitama like that is pure evil!!! I feel really hurt for Saitama. I even wanna cry for people treating him trash like that. He never deserves even a bit of it. People are so cruel!!!

I feel really bad for Saitama. My heart hurts so much. For people to say that after he saved them is evil. It hurts a lot. I'm sure he is hurt a lot too but just doesn't wanna show because he is not that kind of person.

Saitama also raise from C-Class 5th to 2nd. Great!


Words of wisdom:
-You are strong. I was able to meet you by chance, but more than that, you can't let such a rotten industry get to you!! That's why you need to take it on yourself. You'll be told to quit more than once on the road you've taken.

Puri-Puri Prisoner fights with the Deep Sea King but not even he can destroy him, multiple heros try but fail. Saitama saves the day.
We should be deeply thankful for every single hero even though they'll probably never be as strong as Saitama.
Saitama went up to B class rank 101.
I felt bad when he read those mean letters ... why do the citizens keep mistrust him?

This was so well drawn , i just stared at panels at time . Meanwhile we saw considerable character development, and Saitama isnt just Physically overpowered, he has his moral levels on top notch . Not gonna lie though , the way people treat Saitama and him not being credited for Sea King was absolutely maddening

Character development?
A difference between the anime and manga - in the manga the normals are dumb and mean which I don't remember from the anime. The fight takes longer because of backstory flashbacks of heroes who lose during the fight.

One-Punch Man starts to inject some drama in the series, and that is the gradual acceptance of the people, his peers in the Hero Association that Saitama is indeed a true hero. He still continues to prove to the readers that he is the One-Punch Man, capable of defeating his enemies with only one punch. Even though his enemies seem to get stronger and stronger, I don't want that central theme to change.

Volume 5 gives the series some depth and soul without sacrificing the things which has been established in the previous volumes. Being the strongest puncher in the world doesn't mean Saitama has a VIP ticket in both rank promotion and crowd acceptance. After all, not everybody shares the same philosophy - he might be strong, yet some people still see him as a ruse. Though Saitama is a self-proclaimed hero for fun and someone who doesn't need any recognition, we begin to see that this charming bald protagonist is more than the yellow, white and red. He has a heart that hurts too.

This fifth book also expands the ever-growing roster of diverse heroes, some we might never hear of again while some might stay in the story for a while. This gives space for ONE and Yusuke Murata some awesome "filler action" scenes that allow these heroes some time to shine. And that is actually good because the action sequences here are over-the-top awesome!

One-Punch Man doesn't fail to entertain me. It is light, humorous, violent and definitely crazy.

One-Punch Man é daqueles mangás que não me conquistou de pronto, apesar de considerar o seu valor, mas que me tem vindo a apaixonar pouco a pouco. Não tem nada de muito incrível ou arrebatador, só que o ditado "primeiro estranha-se, depois entranha-se" encontra aqui um exemplo perfeito. Este quinto volume traz um combate peculiar que, comparando-o a todos os que o precederam, oferece ao leitor uma panorâmica mais distinta.

Mais ágil, melhor aproveitado, com vários personagens secundários a serem explorados, este quinto volume continua o bom momento do mangá que o quarto volume já havia prometido, trazendo ao leitor uma boa dose de humor sem descurar as cenas de ação. Porém, o One que me perdoe, o que mais gostei neste volume foi a arte de Murata. Um traço forte e expressivo que traz ao leitor o melhor do mangá. 

O quinto volume mostra Genos, Bang e companhia - aparentemente - em maus lençóis. O Rei das Profundezas do Mar ameaça a cidade e os heróis de classe S não lhe conseguem fazer frente. Saitama continua a sua tarefa de coleccionar feitos heróicos para manter a sua classificação de classe C, mas ninguém lhe parece dar muita atenção ou crer muito nos seus poderes.

É a coragem de um ciclista que faz o Rei das Profundezas do Mar finalmente demonstrar alguma fragilidade, ou pelo menos é o que aparenta quando Saitama surge para enfrentar o monstro. Não é preciso dizer o que acontece quando aquele inicia um combate, pois não?

Boa aposta da Devir, a obra de One e Yusuke Murata continua a desenvolver uma história consistente e - uma vez mais aparentemente - ridícula, passando mensagens interessantes, tudo isto com um desenho bem forte. O protagonista, Saitama consegue mostrar carisma sem grande esforço, e as personagens mais secundárias vêm abrilhantar a obra. Quando a fórmula resulta, a série brilha com mais intensidade.

A subversão do shounen começa a resultar melhor nestes últimos volumes, até porque é-nos apresentado agora um rumo para o protagonista. Embora os combates sejam visualmente bonitos, eles não trazem nenhuma surpresa nem emoção ao leitor, e aquilo que os faz chamar o leitor é precisamente a expectativa de que as outras personagens vejam o mesmo que nós. Afinal de contas, somos os únicos que não subestimamos o incrível Saitama.

Choo-choo! Jump on the plot railroading!

This part seems to be moving a bit faster--the pacing could have been a bit slower here. I mean I'd complain if a bunch of Fighto-fighto was put here to slow stuff down... but those complaints would be more about how I'm here for more of the nonsense than the Fighto-fighto--and not about the pacing

I mean, at least give some panels for Puri Puri Prisoner's magical girl transformation. I will note that I do enjoy that the bonus comic in the last volume did recontentualise Puri Puri Prisoner's character. Without it, it looks like Puri Puri Prisoner is a gay rapist. After that bonus chapter in the last issue, it seems he just chooses to lock himself up in prison--doing a jail break to do heroics as he is needed. Yes, he is kind of a gross guy, sure--but lots of guys are gross. This guy is just being gross to other men, instead of being gross to women. He seems to exist as a bit of a weird mirror to how women are presented in the media by men... by having a man presented that way by a man. Also, he does have a few moments where he can be fun

I do also enjoy the weird silly doodles that also occur. Though, wish there were more of those

I suspect this bit is done a bit quicker, as it is hard to have a bunch of stuff where Saitama is involved in utter nonsense in Class C, without it feeling a bit same'y. People might complain about filler--but I typically have no issue with filler in this series if I am laughing at the sheer audacity of it all

The Bonus Comic does show what some of that might have looked like

This set of events kind of went by a bit quicker--and could have had two or three pauses for either absolute nonsense (what I am here for) or a bit more Fighto-fighto (which other people are all about--shrug)

Not certain if I want to call Genos a Jobber or a Carpenter though

Saitama affronta il potentissimo Re degli Abissi quando proprio tutti gli altri eroi che si sono ritrovati contro di lui non sono riusciti a fare altro che soccombere in modo più o meno rapido. Ma ovviamente il Nostro non cambia il suo modus operandi e la creatura si ritrova a terra dopo un solo pugno. La scalata alla classifica degli eroi si rivela ben diversa, comunque da una semplice successione di cazzotti.
Altro numero davvero divertente, per una serie che incuriosisce e aggiunge sempre elementi, nonostante parta da una situazione tanto estrema da far temere che gli elementi per una crescita del racconto siano ben pochi.
Disegni ancora una volta molto belli, particolareggiati e chiari nelle fasi dinamiche.

The artwork is just … *chefs kiss* lovely.

So far I think this is my favorite volume. I enjoyed getting to see some character development for Saitama and insight into how he feels about being labeled a “villain” for doing hero work in his own disastrous way.

Genos, Deep Sea King, and Sonic are definitely favorite characters of mine aside from Saitama of course. I’m having so much fun reading this.

"Guru Saitama, apa tak masalah? Kalau itulah jalan yang guru pilih. Aku takkan bicara lagi. Tapi kalau menjadikan publik sebagai musuh. Apa guru bisa menjalankan profesi sebagai hero?"
Saitama keren banget 😍😍 Bisa kepikiran soal membuat Hero lain terlihat lebih baik, meski sebenarnya Saitama berhasil mengalahkan Raja laut seorang diri 😭😭
Selamat untuk kenaikan levelnya Saitama! 😊🎉

Not as interesting as the last book and takes some time before One Punch makes an appearance. Still an intriguing series but not the best volume and only offers little insight into the bigger mythology of the series.
