Ren didn't see Ema from the time he stepped in the castle. He searched for her and found her near a lake in the inner region. She sitting on ground with her back resting on a tree. She was focused on watching lake that she didn't react to Ren's call until he tapped her shoulder while sitting beside her.
Ema started talking after a moment of silence. She said that this place was her country and her father is Shogun to this place ; this country's strength is far greater than today's Navy.
" The sky is beautiful at night here ", Ema finally smiled after the tragic story. Ren told others to everyone and they decided to stay for a night. Ren saw alll of them were near the lake with some relief, exhausted and sleepy face. Ren felt even the sunset is beautiful with the lake reflecting the perfect image of the sun.
Ren talked with Ema about many things which made her smile and laugh. Marco, Jozu, Bay joined them along with Shanks and buggy. Even Teach joined them because all were in same generation. Speaking of Teach, Ren thought of killing him first but decided against it and he even thought of helping him.
Next hour, when the sunset Ren saw the most beautiful sky. With all the cluster of stars diagonally which filled the sky, moon at one end and lake which reflected all the things in the sky. Ren inhaled deeply breath when he saw it. Not of him, even the most experienced pirates Whitebeard and Roger were mesmerized by the beauty. Ema smiled proudly seeing them.
Ren saw her smile and was stuck there. He felt that her smile was more gorgeous than the sky. Ema saw his heated gaze and turned away. Ren laughed awkwardly but his first step to conquer her heart was success seeing her red ears.
" It's really beautiful to see. Only if my wife is here ", Roger sighed. Others including Rayleigh was surprised by that statement. He didn't said anything about his marriage during their journey. " Where is she? I can take you there now ", Ren asked as he know who he was talking about. Others informed Ren's abilities and Roger told the location Baterilla, South Blue where Rouge lives. Portgas D Rouge joined them. They had a party as Rouge cooked the food which has heavenly taste. Ren felt hopeless when he saw Rouge stretching her hand to serve the food because she ate Gomu Gomu no mi which Luffy should eat for his journey and Ren want to save Roger life too.
===================================
The next thing that happened was a big news wrote by Morgans about Roger pirates along with Whitebeard pirates solving the mystery of the world. It was featured that Roger was first to solve the mystery and conquer the Grand line and Whitebeard was defeated by him.
It was year 1498 when the word heard the new which should be revealed at 1499. Roger still has a year or two to live. Rouge requested Roger to live with her without any interference from World Govt. Oden took this chance to invite Roger to his homeland, Wano. Roger agreed to her request and announced that crew will be disbanded. It was a heavy blow for Roger pirates but followed his order.
Before setting sail Ren wanted to use his Goro Goro no mi to see the whole island. He can feel all the sounds in the island from a living to an object. He felt there is 3d radar inside his head. He teleported to the location he was shocked of. It was a broken tree at the end of the island. Yami yami no mi is hanging on a branch which seem to be fall in the sea at any moment. Ren took the fruit thinking that his luck is too good. First Goro Goro no mi then Yami yami no mi.
These two fruits were not in the plan to defeat Imu. Ren needs two fruits which are quite important for Ema and his love life. He don't have a clue to find the first fruit at all.
There are 4 other poneglyphs which tells the history, Void century in some corners of the island. The history was about Imu, the true ruler of World and how she betrayed the Great Kingdom by turning sides to 20 kingdoms.
It is just a simple information but the impact on the world will be large as many think World Nobles are like gods. Ren said the whole history to Morgans. He couldn't hold this big news and published it next day which took everyone including 5 elders by surprise. It was sensational new more bigger than Roger declared as pirate king.
The elders dispatched another paper saying that whole thing was a conspiracy. Many always believe in World Govt statement but some has their own doubts.
Without any delay, Ren went to Green Bit, Dressrosa to get his first devil fruit ability. He used his haki along with Goro Goro no mi to see the whole island. Ren saw Tontatta Kingdom under the Green Bit. He searched for the princess Mansherry but she was not there. Then he searched for her fruit, Heal Heal fruit and it was stored in the castle where the tribal chief stays. He opened a door and touched the fruit. He copied it and left the place to search for the next important fruit.
