[Old Apple] Shi Si Suu

In this 8-minute uncensored 3D (AI-assisted) animation by Old Apple, the character 祀 (Si / スー) from Arknights: Endfield (明日方舟：終末地 / Arknights Endfield) is featured in an adult-oriented scene.
Si is a 6★ Cryo Supporter and Feranmut Proxy associated with the Hongshan Academy of Sciences. She has a playful, curious, and somewhat tsundere personality, with distinctive green hair, horns, and pointed ears. The short (released around October 20–22, 2026, as the “26.10.22” entry) follows Old Apple’s typical style of high-quality AI-enhanced animations of popular game characters, often including a brief introductory setup before the main content.
