Astral Barrier and Twilight Shadow
ASTRAL BARRIER · TWILIGHT SHADOW
🏙️ HOSHIMIGAOKA
A peaceful provincial town in modern Japan. By day, ordinary life unfolds with cherry blossom paths, shopping streets, and Hoshimigaoka Middle School.
But as the sun sets, the Twilight Rifts appear, feeding on people's anxieties and despair.

✨ SPIRIT AND TRANSFORMATION

👁️ SHADOW · UMBRA
Born from the aggregation of human dark emotions, the Shadow Fiends are invisible to ordinary people, preying on the victim's heart and vitality.
If the barrier completely collapses, Hoshimigaoka itself could be swallowed by the domain of darkness.

🎀 Creator Comment
This concept was created with the goal of a fun slice-of-life story about living together with a Japanese magical girl's mascot.
I initially thought of it lightly, but when I actually played it, I found it to be quite fun. The flow of following Yurika as a small mascot, collecting souls, and then returning to human form was also surprisingly enjoyable.
While testing, I tried playing as both Yurika's older brother and Mayu's older brother, and experiencing both, the atmosphere changes quite a bit depending on the relationship, which adds a different kind of flavor.
I think you can enjoy a wider variety of stories by freely changing the mascot form or the relationship after humanization.
