I loved ace when he first appeared too!! Actually, he was my fav. Character I never imagined him in yaois either xD feels weird reading this!
And it's your lucky day! I'm huge one piece fan and the arc you are mentioning is water seven arc (where robin leave/ luffy and usopp get in a fight) and it is from EP 229 till EP 263 but it is soon followed by another arc which is continuing the previous one named Enies lobby (here is when they rescue robin/ first appearance to sogeking) and this start from ep. 264 till 290 then there is extras but it recontinue from 293-302 and another extra before it continue again 304-312
So depending if you finished this or no you now know where to restart! And ace will reappear again in future arc (422 forward) ^-^
Watching the Marineford arc made me sad
I haven't watched ONe Piece for a long time and when I saw Ace in an episode, I instantly liked him.
NEVER HAVE I IMAGINED TO BE IN A DJ DESPITE BEING A YAOILOVER MYSELF BUT, I surprisingly liked it. I'm new to the ship.
Zoro x Robin have always been my ship on One piece so, this is new XD
I really should catch up on One Piece. I'm still at the early stages, where Luffy and the crew were trying to save Robin (I think this was when a train could travel on water or something). If you don't mind me asking, do you know what episodes they were?
