Criminal Border 1st Offence is the English-market name used by Kagura Games for the first installment of Purple Software’s Windows visual novel. On Steam, the same installment is listed as Liminal Border Part I. Its story follows a fan-video creator whose fictional trance-inducing video draws him into a scheme proposed by a classmate. Kagura Games’ listing and the Steam listing identify the product and its platform details.
What is Criminal Border 1st Offence?
It is a PC visual novel developed by Purple Software and published in English by Shiravune. The English-market seller page uses the name Criminal Border 1st Offence, while Steam calls the game Liminal Border Part I. These are two names for the first installment, not evidence of two separate games. Steam lists November 13, 2023 as its release date. Steam’s listing uses the Liminal Border Part I title; Kagura Games’ product page uses Criminal Border 1st Offence.
What is the story about?
Itsuki Ninomae makes fan videos and accidentally creates what the seller describes as a “digital hypnotism movie,” a fictional device that can put viewers into a trance. When he shows it to Rin Akinashi, he discovers that her polished, high-achieving public image conceals secrets. Rin proposes turning the video into a lucrative business, drawing the story toward criminal underworld activity. This is a fictional premise, not a claim about a real-world hypnotism technique. Kagura Games’ description and Steam’s description outline the setup.
Where can you play it, and what language does it support?
The title is a Windows visual novel. Kagura Games describes its version as DRM-free and says it does not require an internet connection; its product page identifies Windows as the supported operating system. Steam lists English interface and subtitles. These details apply to the named storefront listings, so check the specific listing before buying rather than assuming editions or configurations are interchangeable. Kagura Games and Steam provide the respective product information.

How does adult content availability differ by edition?
Kagura Games marks its product as adult content and says buyers must be 18 or older. A review of the Steam release reports that a separate R18 patch is required to see adult content in that edition. This is edition-specific information, not a guarantee about every storefront or the current patch process. Check the current listing and its instructions for the edition you intend to play. Kagura Games’ listing states its age requirement; NookGaming’s review discusses the Steam release’s patch requirement.
