Preliminary Spoiler

Saiga Riki-Oh is 21. He is in prison for just his first offense. He received a three year sentence for assault, and was imprisoned the year previous. He possesses a robust body, superior intelligence, and a remarkably violent nature. He is marked as a particularly dangerous criminal requiring special attention.

He has five bullets stuck in his chest.

One time, Riki-Oh punches a dude so hard his arm goes elbow deep into flesh till his fist tears out the other side. Minutes later he punches another dude so hard the man's ribs burst out of his side from the impact.

He has a ...

The story of Riki-Oh is about a "Violence Hero" whose seeks to understand his purpose and uncover his family roots, however his journey is filled with action, sorrow and a surprising religious undertone often hinting at repentance.

At first glance, Riki-Oh just seems to be about a guy who punches people and makes them die violently; just juvenile stuff. But to those familiar with manly series, know that basic plots often leads to a more developed main character; a man who embodies the traits of a good person but is willing to become violent to protect the weak and punish evil.

It goes without saying that this ...

Most people will know Riki-Oh from the early nineties flick that has garnered quite the cult following, especially after some of the ridiculously over-the-top fight scenes appeared on the internet years ago. Since then, I only ever hear about the movie, never about the manga on which it is based. So I strapped myself in for a testosterone laden 75-chapter romp, and boy was I in for a surprise.

Most people drop Riki-Oh after the first ten or fifteen chapters because the story goes from crazy to fucking insane. Riki-Oh begins as what appears to be a prison drama, where our titular character is a huge ...

Riki-Oh... Riki-Oh...
Honestly I started reading it without too much expectations. I've discovered it from a bottom of a very very long line of recommendations for Berserk.
I've read Beatnik's review and decided to give it a shot, but after reading 2 chapters I put that manga down.

But for some reason I kept reading it.

And that's what I think:
In one word E-P-I-C!

The story lacks a little bit, it is quite stupid at start and honestly? Untill the very end it doesn't really change. The twists are childish and idiotic, the battles are very short and gruesome but have no freakin' logic behind them. But that's ...

oh boi where to begin

This is the kind of series you have to shut your brain off. Any attempt to understand the story will simply backfire on you.

There are 5 main arcs in this series. Every arc feels like the last one. Everytime your like ok now this is the end. turns out there is a bigger bad waiting for you.

The story changes per arc. Mostly because the information isn't revealed then. At first its prison break. Than its underground fighting, than its something, than its something else. You think this series is crazy now? Wait till you read the next chapter. There is ...

"even God needs salvation"

Riki-Oh is a young kid with great intelligence and an ungodly amount of strength who finds himself in a max security prison serving out his 3 year sentence for assault. unbeknownst to the reader, this prison will be a very large hint into finding out the true secrets about his long lost biological family. Thats about as much story i can really give without spoiling too much because any other hints gives away the greatness. Its a classic shounen manga from the 90s so the story is a little generic and repetitive as Riki-Oh goes through the same process of endless ...

Preliminary (13/77 chp)
Where to start . . . i guess I'll start at the finale, in the last 15 or so chapters things went crazy, I've heard of religious symbolism, but this is basically a religious deepthroat. The main character is a guy named riki who goes to jail (that's the worst arc btw) and just decimates prison bullies, most of the time big bads have an out of nowhere redemption and then double cross him like "oh wow villain number 400 stabbed riki in the back, what a twist, I'm so incredibly shook" and i think the author has a fetish for swords, one arc the ...
