In the late 1990s, with society descending into totalitarianism and anarchy, comes Saiga Riki-Oh, a lone wolf devoted to rooting out people's evil karma. To reconnect with a long-lost brother and solve the mystery behind the separated family and its relation to the Star of David on his hand, he punches through gangsters, corrupt martial artists, and more, all while drawing an equal number of hotblooded supporters and insane enemies.

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 read more

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 read more

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 read more

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 read more
