If you cannot access those, waiting for an official English release or a fan translation (from trusted groups like LHTranslation or A Pair of 2+ ) will at least give you readable, cleaned images—though still not “raw” Japanese.
The availability of specific manga chapters can vary based on your location and the platforms available to you. If "Slow Life in the World of Eroge" is not widely available, you might need to explore various sources or wait for an official release. Always prioritize official and legal sources when possible.
