This might sound presumptuous, but please know translators' ultimate goal is never to work against you - we simply want to honor your creations while making them accessible across cultures.

Translater would carefully study such notes, and I believe most translators would gladly include response letters explaining their localization choices in translated editions.

I noticed your comment about wanting to finalize characters' kanji names yourself. May I suggest adding a letter-style afterword in the manga where you share your vision for each character?

The "official piracy" idea isn't needed - just adding short character notes after main chapters would keep settings consistent. Like I said earlier, your real fans will spread your stories naturally.
Wishing you all the best.

Instead of relying on comics for overseas income, selling official merchandise abroad would work better.

As fans in regions with adult content bans have said, we support you just as much as Japanese fans - but through buying official merchandise instead of digital/print copies (though we'd buy those too if possible).
