One Piece

While Luffy and his allies continue fighting on Level 4, Buggy and Mr. 3 reach Level 2 and release the prisoners there to cause a riot to cover their escape. Meanwhile, Blackbeard arrives at the prison and begins attacking the guards to force his way in. Hannyabal, en route to Level 4, is overwhelmed by these developments until Magellan reveals that he has suppressed the riot on Level 2 and is releasing Shiryu to deal with Blackbeard. Shiryu, immediately after being released and given his sword, kills all the guards sent to release him. (Source: Wikipedia) Summit War saga: Impel Down arc: (19/27)
