Normally English or Malay and even at times Japanese if I can't find a manga in either languages but I don't really know Japanese so I'd ask a friend of mine for help
I never really watched one piece and only saw bits and pieces of it so I can't really give an opinion. I'm not that great with super long series sweats at the 800+ eps it has My friend likes it though!
Ahh no problem and thank you~!
