My fault. It is from the [REM9 (Hamiltan)] NamiRobi OneShota Vacance (One Piece) doujin page 2: [nhentai.net] https://nhentai.net/g/416776/ The speakers are teenage boys and I ended up going for 'Big sisters' and 'big sis'. I thought some dialogues like in page 29 would perhaps use the term 'Nee-chan' better since the boy here is teasing Nico Robin. Yet again I guess something like 'Siiss~" might work too. Thank you for responding btw.
You're welcome (IMG:[invalid] style_emoticons/default/smile.gif) For 29 I think even 'You/Your" is fine because it sounds natural in English.
Great and very useful vocabulary, but definitions are very hit and miss, you would be better off cross checking them elsewhere. For example explanation of chuunibyou misrepresents the term by a long shot.
