What's Ishikawa's backstory in the The Matrix, which was designed to be something of a live-action anime.
The popularity of the Suicide Squad and Scarlett Johannson took over, but despite its reverence to the source material - right down to recreating entire sequences - the 2017 movie underperformed.
In most Ghost In The Shell stories, the focus is usually on Kusanagi or Batou but Public Security Section 9 has way more team . This includes Togusa, sniper Saito and undercover operative Paz. While he doesn't get out in the field a whole lot, Ishikawa is also a key member of the team. Ishikawa is seemingly the oldest member and Section 9's resident techie. Whenever there needs to be lengthy exposition involving technology or hacking, Ishikawa is the one to deliver it.
Like Togusa, Ishikawa is one of the least cybernetically augmented of Section 9. He's one of Ghost In The Shell's most chilled-out characters too, sporting a crusty beard and casual clothes, which works fine since he's rarely in actual combat. Having previously served with Kusanagi and Batou in South America, he was one of the first recruited to the team. He also owns a pachinko parlor and is known to enjoy a drink or two.
Like most of the ing of Section 9, the The Leftovers) is mostly a background figure, but presumably, his backstory is somewhat similar to the anime. This version of the character is at least seen engaged in one of the movie's firefights, meaning he gets out of the office once in a while.
