The DVD box describes this as "hard edged" action. Simply stated, this is Japanese grindhouse.
The plot is fairly simple. Shozo (Tak Sakaguchi), who is a great fighter, but not the sharpest tack in the box, returns to Japan to discover his crime boss father has been over-thrown. He opts to get his empire back. About midway through the film he is transformed into the man you see on the cover. The action is over the top, sometimes 3 Stooges style. In an early scene a man steps on a landmine and uses it to blow himself up so he can soar through the air and land in the enemy camp.
The story includes bad hair pieces, lines from American films, school girl uniforms, pink ooze squirting from a cell phone, a nurse with Freddy's claw, and a man who dodges bullets. This is for extreme grindhouse fans who enjoy immature bloody movies. If you didn't enjoy the American "Planet Terror" or "Smokin' Aces" films, you should pass on this one. The comedy is called "manga style." It is similar to what we call "mid-brow" humor...like listening to Lou Reed, but without any political commentary. I might have to watch a few more of these films before I can decide if I really like them or not. English subtitles are used in the film and in the extra features.
Parental Guide: F-bombs, sex, and weird nudity. Excessive blood, killing, and violence.
