A slang for a "true's love kiss" (mostly a "French kiss") in Anime culture, oftenly used in Yuri (lesbian/girls' love genre) while less common on Yaoi (gay/boys' love) and Straight (common boy & girl romance) genres. It is an analogous, yet synonymous pun on another word, "one peace," in a romantic manner, used to refer the love between two partners is considered as their "invaluable and irreplacable treasure" for peaceful ways. Metaphorically, it is NOT the same as Gol D. Roger's treasure in the anime with the same name, but a personal expression/form of love.
Storyteller: "At last - with a fulfilling kiss of purity sticked between their lips, their priceless treasure - the true love between a tomboy prince and a beautiful princess - is finally found in "one peace." And they lived happily ever after..."
Storyteller's daughter: "So the "One Piece" is real! I wanna marry a girl too when I grow up!"
