From MangaHelpers:

Tatsuo, Hide, Satoshi and Aya worked together to cheat people out of money. They tended to target marriage services, where they con money out of people looking for love. They were good at it, until they crossed the wrong guy. Then they saw the world below the surface of dupes to cheat, when the 'collection agency' came for them with extreme violence.

The person who takes Satoshi and Hide, and then Aya and Tatsuo, is a wild-eyed maniac who seems to get off on the torture. There may be hope for Tatsuo, though, because the man recognizes him. The torturer is "Akasada" a bullied kid that Tatsuo knew from school. Now Tatsuo and Aya have been pulled, against their will, into Aka's world. [tethysdust]

Pretty Enjoyable, Very Violent   
Rating: 8.5 / 10.0

Dora is working his way up the underground Torture-for-Hire food chain. Our character is vying to be the most violent in a sufficiently violent and cruel world. This series features a medley of ways to torture and kill someone. I honestly didn't think there was that many ways to torture a person; but, then again, I am not a sadistic sociopath. Senseless Violence? Sure. It is guilty pleasure that I not too guilty about. They are no hope spots in this manga. When you think someone might be the least bit redeemable, they turn their sadist level up to eleven. There is a homosexual sadist who acts as a mentor to the protagonist. While the Depraved Homosexual may be a staple archetype in Western horror and thriller (I blame homophobia and Jeffrey Dahmer), it felt fresh here. The guy is fleshed out. He is not agonizingly cliche nor flamboyant. However, please keep in mind he is a sexual sadist and with that label, he is completely unhinged. I like Dora's character development and fleshing out of other characters. There are twist and turns about who Dora should trust in his role and I was floored by some reveals.

This manga is going on the right path. It should be given a try even though the scanlators dropped the comic. Maybe they collapsed from all the violence? It has very nice art. Highly detailed and uncensored. It's worth it.

Trigger Warning: When there is a women involved, you can expect rape. Expect it from the protagonist. It is a special kind of torture reserved only for the targeted women or the loved ones of those targeted or whoever he thinks deserves it (OK, I admit, it's not that special to him). He is not shy about dishing it out.

Fun Fact: Shimauma's Japanese for zebra, シマウマ。 縞馬. The second kanji which stands for horse, looks like an elephant. So cute. <3
