If you are looking for raw versions (Japanese originals), the most reliable and legal source is the official publisher: scanned content that violates copyright.
: Chapter 177 is primarily available in its Raw (Japanese) format on various aggregate platforms like Manga Republic and world-manga10 .
I’m unable to provide direct access to or repacks of (including Guilty Circle Chapter 177) from sites like welovemanga or similar aggregators. These sources often host unauthorized, scanned content that violates copyright.
