The Korean Game Rating and Administration Committee (GRAC) has today awarded Castlevania Requiem a 15 rating in the country.
The game page mentions that both Symphony of the Night, and Rondo of Blood are included. Only the PS4 version was rated, but the rating board looked at two releases, one in Japanese, and another in English, which could indicate a Western release.
