## Plot

Using Ichi as a tool, the "Old Geezer" plots to kill the Anjo yakuza family leader, Yoshio Anjo, and steal his money. With Anjo's death, his top yakuza, Masao Kakihara, sets out to find his leader's murderer; Kakihara searches for Ichi, while the younger man effortlessly kills off the remaining Anjo family members. This cycle of killing and searching leads the two closer together, revealing Ichi's psychological manipulation and Kakihara's obsession of pain and torture. When the two finally meet, they confront their deepest and most suppressed desires, resulting in Ichi's recovery and Kakihara's demise.

## Reception

Tomo Machiyama from Pulp included the series on the "Most Hellish (Untranslated) Manga....ever!!!" list. Machiyama, noting the gruesome and violent content of the series commented: "No wonder this comic was banned in some prefectures, but actually this story, by the creator of PULP's very own Voyeurs, Inc., is a really profound existentialist story. In peaceful consumerist society, how do we make sure we are alive?".
Chris Beveridge from AnimeOnDVD called the OVA "an interesting look into the mind and how it deals with violence, pressure and the mix of sex into everything." Beveridge added that the "over the top violence" "doesn't hit the comical level like Natural Born Killers but rather resides in the disturbing level instead". He concluded: "[i]t's violent, it's sexual and it doesn't make any bones about it." Reviewing the OVA, Bamboo Dong from Anime News Network called it "nothing but an excuse to fit as much sex and violence in a 47 minute excursion as possible", adding that there was potential to use the psychological aspects of the story and explore the human mind, but that "[t]hey were too busy satisfying their testosterone levels". Theron Martin from the same website felt that the story is "perfectly believable" and "convince[s] the viewer that Ichi's lethal tendencies didn't come from nowhere" because it follows the "common elements you hear about in the backgrounds of true killers". He dismissed the "substandard animation" as problematic but praised the music of "heavy driving techno themes" that provide an "edgy mood and tone for the series".
Mike Toole from Anime Jump, commenting the artwork of the OVA, stated: "Its scenery is sparse, its animation jarring and clumsy, its character designs ugly as sin", comparing it to the "drawings of a bored eleven-year-old boy than that of a seasoned animation team", adding, however, that it "feels calculated" and fitting to its "terrifying" and violent world. Toole wrote that the OVA is "like a Cronenberg or De Palma movie, only without any of the subtlety". Toole concluded: "Only hardcore Miike and Ichi devotees will want to own it, but it's certainly worth a look." Chris Feldman from Animation World Network highlighted the writing of the OVA, commenting that "[a]lmost no familiarity with either the manga or movie is required to fully understand what is happening." He added that the OVA would appeal to "anyone looking for an anime that would never get on American TV", commenting that "[a]fter the edit, there wouldn't be enough to fill a half-hour on Adult Swim", and concluded: "for the fans of the movie and manga Ichi the Killer: Episode Zero is a must see".
