我的傲娇妹妹 MY TSUNDERE SISTER

My Tsundere Sister launched on Steam on August 11, 2026. It is a short visual novel (approximately 3–4 hours of gameplay) and the second entry in the "My" series by SuiKa Soft, following My Cold Girlfriend. A theme song album ("Their Secret Melodies") was released alongside the game on August 12, 2026 as a separate DLC — this is the only DLC listed, and it has already shipped. The developer also issued a v1.01 patch on August 13, 2026 addressing minor polish items such as audio balancing, CG gallery additions, and video performance. No future content, expansions, or roadmap have been announced. However, because the game only launched two days ago, there is simply not enough post-launch history to determine whether the developer intends to add further content.
