One Piece Season 9 Episode 277

The Tragedy of Ohara! The Terror of the Buster Call!

Professor Clover is allowed to speak with one of the Elder Stars and reports of their research. He describes a civilization that existed hundreds of years ago and vanished at the time that the world government assumed power. He considers the collective evidence, which leads him to believe that the government tried to erase their former enemies from history. After stating that Ohara has learned too much, the Elder Star orders Spandaine to kill the professor and to give the order to destroy the island. Suddenly, the library is set aflame; while the scholars try to save the books, Robin admits to being an archeologist and unites with her mother. However, their union does not last long. Around them, cannon shots from the Buster Call's battleships start to hail down and Olvia sends her daughter off with Saulo to flee the island, while she joins the effort to save the library's knowledge.
