From a visual standpoint, this episode contains heavy particle effects—alchemy circles, summoning sequences, and full CGI Chemy fights. Hikounin-Raws’ high-bitrate capture is essential here; in lower-quality releases, the alchemy glyphs against dark backgrounds become a pixelated mess. The 404F release likely preserves the subtle gradations of the Dark Kings’ costumes and the metallic sheen of the Rider suits.

This string usually denotes technical encoding parameters or the release group's internal tracking. It might refer to a CRC error check, a specific encoder setting (like CRF values), or simply a continuation of the file naming convention used by the group. The presence of such tags is a signal to the downloader: This is a specific, trackable release. It ensures that if a file is corrupted or a re-release is issued, the user knows exactly which version they possess. It is the digital fingerprint of the file.

Unlike smaller fansub groups that recode to smaller sizes (720p, 480p), Hikounin-Raws is infamous for distributing or even untouched TS (transport stream) captures .

So the next time you see that string of text, know that behind the hexadecimal and the hyphens lies the pure, unsubbed heartbeat of Japanese heroism: a Kamen Rider in 1080p, frame by perfect frame.
