在日本快要進入“幕末”之前的一段時間，
一對兄弟被逼在動亂的世界中掙扎求存。
哥哥雪村翔太郎(14歲)和弟弟雪村源太郎(10歲)───相依為命。
由於媽媽臨終前說道：「如果你是弱者，你便會死!」
於是兩兄弟決定為了變強而踏上成為武士之道路。
在這個混亂的時代和地獄般的世界，
他們遇到更多無情的考驗和體驗人世間的冷酷和殘忍…

Four hardcore heroes. One high-speed torpedo boat. Ten thousand bullets! R to L (Japanese Style). Roberta's vendetta continues as Revy and Rock enlist some old acquaintances to try and catch up with Roberta before it's too late. They're going to have to get in line since Roberta's got everyone from a U.S. military black ops unit to her ex-F.A.R.C. comrades gunning for her, not to mention the CIA and the NSA. When the turmoil becomes more than the city's criminal underworld can bear, Balalaika and her Hotel Moscow commandos enter the game. With so many players at the table, it's winner take all, and the stakes couldn't be higher! Lock n' load with the baddest group of mercenaries ever to hit the high seas of Southeast Asia! Aboard their World War II torpedo boat, the "Black Lagoon," Dutch the Boss, Benny the Mechanic, Revy Two Hand, and Rock, the salaryman from Japan, deliver anything, anywhere. In the dangerous underworld of the Russian Mafia, Chinese triads, Colombian drug cartels, crazed assassins, and ruthless mercenaries, it's hard to know who to trust. But if you've got a delivery to make, and you don't mind a little property damage along the way, you can count on the crew of the "Black Lagoon"!

拔枪、轰杀————Black Lagoon
没有各种花里胡哨的招式，没有造型怪异来历不凡的奇门兵器，更没有无谓多余的碎碎念。
拔枪，轰杀，有时候战斗就是如此简单。
这显然不是一个由一群高尚主角和花哨对白堆砌起来的浪漫故事：被[黑色礁湖号]成员绑架的上班族冈岛绿郎在得知自己被公司抛弃之后，便索性加入[黑色礁湖号]。与黑壮汉老板达智、火爆枪手利颖和科技达人卑利一同经营运输业，当然，“偶尔会做些触犯法例的事”……
作品中的战斗流畅、富有魄力，丝毫没有拖沓感，给人的感觉类似于好莱坞动作大片，简单、华丽、直截了当、气势十足；同时，广江乾净的画风也十分贴合作品中战斗给人的感觉。
事实上对于这么一部豪快的战斗系作品而言，太多的形容词和“深层分析”都似乎显得啰嗦和不必要。作为观众，我们只需要享受这种快感就好。
绿仔 (Rock)
男一号，日本人，前上班族，目前是礁湖号的见习水手，经常和利颖一起行动，性格温和理智，为人善良厚道……
利颖 (Levi)
可以算是女一号。美裔中国人，礁湖号上的枪手，性格暴躁凶悍，偏好用暴力来解决问题。顺便说一句，我很喜欢她身上的纹身。
达智 (Dutch)
没有提到国籍，不过曾参加过越战，应该是美国人。礁湖号的老板，按卑利的话说，“即顽固又理智，和怪人差不多”，作战也是强悍的硬派风格。他跟巴拉莱卡的关系似乎非同一般。
卑利 (Benny)
美裔犹太人，因为某些原因，被黑手党和FBI追捕，科技达人，负责黑色礁湖号上的各种高科技设备。
巴拉莱卡 (Balalaika)
俄罗斯御姐，黑帮“莫斯科酒店”在泰国分区的头儿，以前是苏军上尉。黑色礁湖号所接受的委托，有很多都来自她。
张北伟 (Chang)
香港三合会泰国分区的大哥，有着中国人特有的刚柔并济的作风，身手了得，真名周润发……

Rock and Revy form an uneasy alliance with Ginji, the Washimine-gumi's top enforcer, to rescue Yukio from her kidnappers. Even if she can be freed, Rock finds Yukio's position as the new head of the Washimine-gumi hard to accept, especially when it calls his beliefs and loyalties into question. The conflict between Hotel Moscow and the Washimine spirals into greater violence, setting Rock and Revy on a collision course with Balalaika, and ultimately, a shocking climax that will change Rock forever.

Lock n' load with the baddest soldiers of fortune ever to hit the high seas of Southeast Asia! Aboard their World War II era torpedo boat, the Black Lagoon, Dutch the Boss, Benny the Mechanic, Revy Two Hand, and Rock, the salary-man from Japan, deliver anything, anywhere. In the dangerous underworld of the Russian Mafia, Chinese Triads, Colombian drug cartels, crazed assassins, and ruthless mercenaries, it's hard to know who to trust. But if you've got a delivery to make, and you don't mind a little property damage along the way, you can count on the crew of the Black Lagoon!
