Gangsta seinen anime

Two bulky men named Nicholas Brown and Worick Arcangelo are underground mercenaries. If you are in a serious pinch and don’t know who to call, you can just ring these bros a bell and they’ll take care of the rest. That’s how Nicholas and Worick have made a name for themselves by taking on jobs that no one but them can accomplish.

Now even the police and mob syndicates are more than willing to hire them but when they end up destroying a local pimp and decide to protect a prostitute from the people who were after them, this seemingly stagnant balance of power begins to crumble.

Will the two bros be able to handle this upcoming change? Well, of course bros can handle anything. Can’t they?

09. Black Lagoon

Anime With OP MC

Are you tired of all those cringe tsundere and yandere waifus? Do you want a cool and badass woman to fawn over? Well, I’ve got you covered.

Black Lagoon is an anime that features Revy, the living personification of badassery. Her character is so beguiling that even girls of all ages fawn over her. As for the anime itself, the story takes place in a crime-ridden city of Thailand. There’s a group called Black Lagoon.

They’re basically pirates but one day, they end up taking an overseas Japanese worker hostage and that’s how this story begins. I’m telling you, even if you watch the anime just for Revy, you’ll also end up impressed with the plot. It’s just that good.

08. My Dress-Up Darling

new winter anime of 2022

Now for the anime that’s been dominating the winter 2022 ranking charts ever since its inception on January 9th 2022, My Dress-Up Darling is an anime that rose to the top even though the final season of Attack on Titan and the second season of Demon Slayer were also airing in the same season. If that doesn’t catch your interest in this anime, I don’t know what will.

The story might be simplistic, considering how it’s basically about cosplays but the character will rip your heart off, especially Marin Kitagawa. She is the greatest waifu material we’ve seen in ages.

06. Berserk

Guts (Berserk) Strongest Anime Swordsmen

Berserk is a manga that goes beyond the term legendary. It has consistently managed to stay at the very top of the manga rankings for decades; that’s the level we are talking about. It’s genuinely sad how the author died before he could finish this era of defined work of fiction.

However, his legacy still remains. It is the reason why Berserk has a total ranking of 8.7 out of 10, and trust me, it’s still very much worth reading even if it’s incomplete.

Although Berserk has yet to receive an anime adaptation that does it justice. The 1997 adaptation of Berserk is still very good and can even serve as your introduction to this epic.

Steadily maintaining its reputation as a top-tier classic Cowboy Bebop is yet another prestigious work that everyone should watch. The story takes place in the year 2071; several planets and moons have been colonized.

The protagonist named Spike Spiegel. He is also a cowboy who continues transversing the space along with his partners and new members who keep on joining. I’d say this is an anime that everyone should watch.

Space Brothers

Are you tired of the day-to-day mundanity? Do you miss the times of inspiration, the times when you truly felt alive? I know that watching Inazuma Eleven or Pokemon may no longer inspire you but Space Brothers is an anime that can. It’s a realistic slice-of-life drama about two brothers who decide to go to the moon when they were little.

Now, even though decades have passed and only one of them was working on their dreams, the older one starts falling deeper and deeper into the void of regrets until his mom sends the Japanese Space Agency his CV and clears the first selection.

Looks like it’s finally time for the older brother to follow suit. Also, don’t worry; this anime won’t mock your intelligence by pulling off stupid plot conveniences. Its realism inspires you and it makes you feel like living again.

What makes this anime so interesting is how characters have transcended past the limitations of their mind and bodies as well as carnal desires, and yet it still manages to depict their individualistic struggles. Does that fascinate you?

Our prodigy is a Phosphophyllite, and I’m telling you, as you delve into this story, the emotional damage will definitely make you shed a few tears.

mystery anime Monster

It has been over 17 years since the monster anime came out and it is still recognized by many fans and critics alike as the greatest seinen anime of all time. Just like One Piece and Attack on Titan are the faces of shounen anime, Monster is the face of seinen anime.

Monster is an anime that’ll continue to stand the test of time and it’ll always be hailed as one of the greatest anime of all time. Watch as an ordinary Japanese doctor living in Germany ends up going face to face with the very kid he faced nine years ago.

The story is harsh, it’s cruel, and it’s sad, but one thing is for sure it is a serious anime with deep meanings and themes. Definitely, Monster is the best seinen anime of all time and still the best seinen anime of 2022.
