Voltage Inc. (Headquarters: Shibuya-ku, Tokyo, CEO: Yuji Tsutani) has announced that the card-based suspense app "Roppongi Sadistic Night" has started a collaboration project with the app game "Assault Lily Last Bullet" from the Assault Lily project, beginning on Friday, April 24, 2026.

"Roppongi Sadistic Night" is a card-based suspense app set in Roppongi, where players tackle incidents alongside a "team" consisting solely of beautiful women. Since its release in 2015, its instinct-appealing stories, multiple endings, and over 4,000 card illustrations have garnered support, and it celebrated its 10th anniversary in November 2025. Currently, the app is rolling out various projects to commemorate the 10th anniversary, and as one of the highlighted projects, it is executing collaborations with multiple titles. This project marks the second installment.

In this project, a collaboration gacha with "Assault Lily Last Bullet" will be held. "Renka Iijima" from "Assault Lily Last Bullet" wearing a collaboration outfit and "Yuki Higashikata" from "Roppongi Sadistic Night" will appear as specially drawn limited cards. Furthermore, this collaboration card features newly recorded voice lines by the popular voice actor Erika Ishitobi. Please enjoy this special card that can only be obtained here.

Also, to commemorate the collaboration, a present campaign will be held on SNS. It is a project where you can win a QUO card set featuring the collaboration illustrations by lottery, so please take this opportunity to participate.

To show our gratitude to the fans who have supported us so far, we are rolling out many special projects to commemorate the 10th anniversary. Please continue to look forward to the ever-evolving "Roppongi Sadistic Night."
