Goichi Suda made a game about seven assassin personalities who share one body. Capcom published it.
The seven answer to Harman Smith, an aging man in a wheelchair. Players could not walk freely: movement was locked to rail-like paths, and the world looked like panels from a cel-shaded graphic novel.
It sold modestly. Some critics called it art; others called it a failure of game design.
About this game
In 2003, Tadayuki Nomaru was a college student drawing part-time at Grasshopper Manufacture. His first job there was killer7. For it he drew a horse racing picture and a gambling woman in a kimono. He says: "I was told I could draw anything I wanted. I was a bit worried whether these would be OK. But they went over really well, and I just kept on churning out art."
Goichi Suda directed killer7, which came out on GameCube in June 2005. On February 7, 2026, at a launch event in Tokyo for a new Grasshopper Manufacture game, he was asked whether he thinks better alone or with his team. These days, he said, he thinks better with the team, in meetings. Up until around killer7, he mostly thought alone.
In 2024, Suda sat down with Shinji Mikami, the creator of Resident Evil, for a Grasshopper Manufacture video. Asked about future projects, Mikami said: "I'd love to see Suda make a sequel to killer7." Suda said he would rather make a complete edition first. In the finished game, Coyote, one of the seven assassins, barely speaks. In the original scenario, he had lots of dialog.

The Story Behind
killer7 emerged from Capcom's 'Capcom Five' initiative, a slate of exclusive GameCube titles intended to revitalize the platform. Of those five, it was the most provocative — a game that interrogated the nature of national identity, violence, and reality itself. Suda51's vision proved too uncompromising for mass audiences but cemented Grasshopper Manufacture's reputation as one of gaming's most distinctive studios.
Tricks & Tales
Capcom's Hiroyuki Kobayashi produced the game.

Released on both GameCube and PlayStation 2. A PC version was released on Steam in 2018.
Maintenance Tips
The GameCube uses a proprietary 8 cm mini-DVD format, and the laser lens is the component most likely to degrade with age — it may struggle to read discs before showing any visible external wear. If a disc fails to load, clean the lens very gently with a lint-free cloth and a small amount of isopropyl alcohol, and avoid using cotton swabs, as loose fibres can lodge inside the mechanism. For discs, wipe in straight lines from the center outward, never in circular motions. The laser's power potentiometer can be adjusted slightly when reading becomes unreliable, but this should be done in very small increments as too much adjustment can damage discs.

What to Watch Out For
Before buying, these are the points worth knowing — from someone who handles original Japanese killer7 copies regularly.
Will this Japanese GameCube game work on a North American or European GameCube?
No. The Nintendo GameCube enforces regional lockout in hardware — Japanese GameCube discs will not boot on Western consoles without modification. Options include a modchip installation, a software exploit on certain early-revision consoles, or a Japanese GameCube. The GameCube uses a proprietary 8cm mini-DVD format that is physically identical across regions; the incompatibility is firmware-enforced.
Do I need a Memory Card to save game progress?
Yes. The GameCube has no internal save storage. A GameCube Memory Card must be inserted into one of the two memory card slots on the front of the console. Cards come in three sizes: Memory Card 59 (59 blocks), 251 (251 blocks), and 1019 (1019 blocks). Check the game manual for the block requirement. Official Nintendo Memory Cards are recommended — third-party cards have higher failure rates and some games detect and reject them.
How should I handle and store a GameCube mini-DVD?
The GameCube uses a proprietary 8cm mini-DVD. Handle by the edges and center hub only. Clean with a soft lint-free cloth, wiping from the center outward in straight radial strokes — never circular. Store in the original case. Mini-DVDs are slightly more vulnerable than standard 12cm discs because any given scratch affects a proportionally larger data area. Avoid heat and humidity.
Before You Buy
Things worth knowing before you buy killer7
A short checklist for buying a used GameCube disc wisely — useful with any seller, anywhere.
-
Choose a seller who tests it before shipping
A copy that has actually been powered on and checked is a known quantity. An untested one is a gamble you only settle after it arrives.
Look for a seller who states it was function-tested and says what they confirmed. A serious seller can tell you exactly what was checked.
-
Check the mini-disc for scratches
GameCube uses small mini-discs; deep scratches cause read errors, while light marks are usually fine.
Ask for a photo of the disc surface and confirmation that it loads.
-
Make sure it fits your console
This is a Japanese GameCube disc. The GameCube is region-locked, so a Japanese disc needs a Japanese console.
Play it on a matching Japanese console or a region-free system, and confirm the listing states the region.
-
Saves use a memory card
GameCube saves to a memory card, so there is no battery in the disc to fail.
Have a GameCube memory card with free blocks ready.
-
Read the seller's reviews and return policy
A 100% positive record across thousands of sales is close to a guarantee — packing, communication and problem-solving all work for everyone. A return policy protects you if something is off.
Read the feedback and confirm a clear return window before you buy.
The last step before buying anywhere is knowing what it's worth.
