When you enter Gemini Town, you meet a Male Traveler who says you can probably get a boat if you ask at the Guild.
Inside the Guild, you meet Jolie Curie - who, along with her sister Maidame Curie, played a very important role in Asdivine Dios.
Izayoi tells Jolie Curie that you need a boat.
(Coincidentally, Jolie Curie was the first NPC to give you a boat in Dios, as well.)
She agrees to lend you one, but only if you'll agree to exterminate a monster in Seirios Grove.
Once the dialogue ends, go ahead and leave town and head for the Grove.
