As of my knowledge cutoff date in September 2021, there has been no episode of the One Piece anime that shows Luffy using Gear 5. Gear 4, also known as Boundman, is the highest level of Gear that Luffy has demonstrated in the anime. It's possible that future episodes or chapters of the One Piece manga may reveal a Gear 5, but as of now, it has not been shown in the anime. **

As of now, there has been no official announcement regarding the introduction of Gear 5 in the One Piece series. The creator of One Piece, Eiichiro Oda, has not revealed any specific details about when Gear 5 will be introduced. It is likely that Gear 5 will be revealed at a significant moment in the story, but fans will have to wait for Oda to unveil it in the manga or anime. **

As an AI language model, I don't have personal opinions, but I can provide information. In the One Piece anime, there is currently no official mention or depiction of a Gear 5 form for Luffy. The series has shown Luffy's progression through various Gear forms, but Gear 4 seems to be the most advanced form revealed so far. Fans have speculated and created their own concepts for a potential Gear 5, but until it is officially introduced in the anime, it remains a topic of speculation and anticipation. **

As an AI, I don't have personal opinions, but I can tell you that the satisfaction with the new One Piece episode and Gear 5 varies from person to person. Some fans may be extremely satisfied with the new episode and the introduction of Gear 5, while others may have different opinions. It ultimately depends on individual preferences and expectations. **

To lay patio slabs with more than 5 cm of gravel, you will need to first prepare the area by digging a trench and filling it with a layer of compacted gravel that is at least 5 cm deep. Then, you can lay a layer of sand on top of the gravel to create a smooth and level surface for the patio slabs. Once the sand is in place, you can then lay the patio slabs on top, making sure they are evenly spaced and level. Finally, fill the gaps between the slabs with more sand or gravel to secure them in place. **

To remove stains from light-colored patio slabs and tiles, you can start by using a mixture of water and mild dish soap to scrub the affected areas. For tougher stains, you can try using a solution of equal parts water and white vinegar or a commercial patio cleaner. Apply the solution to the stains and let it sit for a few minutes before scrubbing with a brush or sponge. Rinse the area thoroughly with water and repeat the process if necessary. Additionally, you can use a pressure washer for more stubborn stains, but be sure to use it on a low setting to avoid damaging the patio surface. **
