In Episode 274 (Answer Us, Robin! The Outcries of the Straw Hat Crew!!), the Strawhat Pirates assemble on the roof of the Court House. They then walk towards the Tower of Justice to join Luffy, and stand against the CP9 members, who are standing in the balcony of the Tower of Justice.
The tune played at the time sounds quite inspiring and feels great to hear. This tune runs from about 20:45 to 21:45 of the episode. Could someone please tell me the name of this tune?
