Chapter 184: Weapons Upgrade

Ben was standing on the Miss Love Duck. He was looking out to sea. "Thank you for everything," a woman said. He turned and saw a woman next to him leaning on his shoulder. She had a pair of black-feathered wings on her back, silver-white hair that extended to her shoulders and brown skin. On her upper-back she had a plume of fire. She was wearing a white backless mini cover-up dress that extended to just above her knees. The dress had short sleeves. She was wearing black high-heels. The woman had a big smile on her face. Ben saw her. She looked up to Ben and said, "I love you." At that moment, a female teenager came running towards them and hugged Ben. She also had a pair of black-feathered wings on her back, silver-white hair that extended to her shoulders and brown skin. She was wearing a yellow dress with flowers on them. Her fire was prominent. As she hugged Ben, she said, "Papa." 

Ben woke up from his sleep. He thought it was a strange dream. He looked next to him and saw Marianne sleeping. She was fast asleep. Ben thought she looked cute, hugging the teddy bear. He would let her sleep. He thought back to his dream, they both looked like Lunarians. He wondered what that could mean. 

Ben got up. He saw his clothes on the floor. He was so used to either BM or HQ being here for me that he got a little lazy. He picked his clothes up and quietly headed towards the door. He opened the door and saw BM there waiting for him with a fresh pair of clothes. 

"Good Morning BM," Ben said.

"Good Morning my lord," BM greeted back.

"What are you doing here?" Ben asked. He was curious to see why she was seemingly waiting outside.

"I was waiting to give you some fresh clothes," BM replied.

"You could have entered?" Ben asked. 

"No my lord, it would breach the girl's privacy. You had mentioned that each room is for the girl and their personal area," BM replied.

"But what about my room?" Ben asked.

"My lord, that is the Captain's room," BM replied. BM did not see anything wrong with entering that room. Ben shrugged his shoulders. Girls have some weird logic at times. 

"Okay," Ben replied. He handed his dirty clothes to BM and took the new one. 

"Thank you my lord, breakfast will be ready soon," BM said as she headed off. Ben nodded and headed to the shower. He walked down the stairs to the shower room. The door opened and he saw Robin wrapped in towels. The first towel covered her head. The second towel covered her body. It showed ample amounts of cleavage. Robin was truly blessed in that department. The towel ran down to just below her thighs. It barely covered her vagina. Robin smiled. 

"Good Morning Captain, nice friend you got there," she teased.

Ben realised he was naked again and covered up. "I am sorry," Ben apologised.

Robin laughed. "We dont mind," Robin replied. She walked away smiling. Ben sighed. He thought of making sure to cover up but the girls are always okay with him walking around naked. 

He entered the shower and saw it was empty. He put his clothes to the side and showered. He took around 5 minutes and finished. He put on his new clothes now. It was a red shirt and black trousers and headed out. He headed up the dining hall stairs to the dining hall and saw most of the girls there. Kaya, Alvida, Mikita, BM, Nojiko, Vivi, Zala, Saphir were sitting around the table. 

"Hi All," Ben greeted. The girls greeted back.

"Where are you sisters Saphir?" Ben asked.

"Emeraude and Rubis are in the weapon`s room with HQ, they said they want to modify some of the weapons," Saphir replied.

"Okay," Ben said. That is nice, he thought. 

"They seem very smart and capable," Nojiko said. 

"Of course, they are my sisters," Saphir said. She looked very proud. 

"Where is Robin and Honey?" Ben asked.

"Robin is getting changed, she had a shower," Zala replied.

"Honey went to look after Marianne," HQ said. 

"Pervert," Kaya said.

"More like beast," Mikita said. 

"My love is gentle," Alvida added. They all laughed. Ben sat down. He thought these girls were sometimes crazy. Zala served Ben his breakfast. Ben thanked her. 

"Captain, I had set the course to the third island and we have arrived," Nojiko said.

"Good job," Ben said. Nojiko smiled. 

"There is a possibility that the Simon Pirate, have an orb, lets secure as many as we can," Ben said

The girls cheered. "Saphir, I want you to stay on the ship today with your sisters," Ben said.

Saphir looked curiously at him. "This is your first official day on the crew and I don't want you to throw yourself in the deep end. I expect fights and they are probably mad as well," Ben added.

"My love cares for his harem," Alvida said.

"But," Saphir said. She wanted to be with Ben and the girls to prove her worth. She loved the atmosphere when they were together yesterday. She felt like she belonged here. She looked dejected. 

"Captain's order," Mikita said. 

"I don't doubt your capability but I don't want them to vent their anger on you today," Ben said. He did not want to throw them into a fight. He wanted to ease them in. 

"It's probably best just for today to stay on the Miss Love Duck and defend her," Nojiko said.

"It is an important task," Kaya added.

"Your Captain gave that order," Zala said.

"He did, I will defend the ship," Saphir said. Ben thought she agreed and had a wide smile on her face.

At that moment, Robin, Marianne and Honey entered the dining hall. Marianne had a wide smile on her face. "Someone had a good night," Alvida teased.

"Pervert," Kaya said.

"You also had that smile," Nojiko said.

"Hey," Kaya said.

"He is something special," Vivi said.

"Marianne are you alright?" Ben asked.

"I am, and ready," Marianne replied as she sat down on the table. 

Zala served them food. Marianne, Zala and Honey thanked her.

"Captain sure has the right equipment," Robin said.

"He does," Honey added.

Saphir licked her lips. 

"Can we not talk about it at the dinner table," Kaya said.

The girls laughed. "Okay, let's change the topic," Alvida said, taking control.

"We need to get HQ, Rubis and Emeraude here, so I can tell the plan for the island," Ben said. 

"We are here Master," HQ said as they entered the door. Rubis and Emeraude were behind her. 

"Sorry we are late," Emeraude, yawning. 

Rubis bowed her head down. They both looked tired. "Were you both up all night?" Ben asked.

Emeraude and Rubis did not reply. "Yes they were," HQ said.

"We were working on the weapon and modifying it," Emeraude said. 

"We are ready for today's work," Rubis said. Her eyes had black shadows. 

"My love is very strict," Alvida said. She had a serious tone.

"He expects double shifts," Mikita said.

"He is very long," Robin said. She winked at Ben.

"We will work hard," Rubis said.

"Yes, we will," Emeraude said. Yesterday was the best day of their life. They felt like they were family and close. They did not want to disappoint them 

"Girls," Ben said, looking at Alvida and Mikita.

Mikita and Alvida laughed. Emeraude and Rubis looked shocked.

"They were just pulling your legs," Vivi said.

"He is a pervert but not mean or horrible," Kaya said.

"Sis, Captain said for us to stay on the ship and protect it," Saphir said.

"Well, I did but now I want you both to rest and sleep today," Ben said. 

"But," Emeraude said.

"Captain's order," Zala said.

"Rubis, Emeraude, your well being is important to me. I won't tell you to stop working overnight but I want you to remember, I care for you both. I want you both to be happy and not overwork yourself," Ben said. 

He looked around and said, "That applies to all you girls." They all smiled. Their hearts melted. 

Rubis and Emeraude could see themself falling in love with this man. They saw their sister who could have hearts in her eyes. "Sure Captain," Emeraude said.

"Sis, don't you want to talk about your upgrades," Rubis said.

"Our work, yes. Everyone, we have modified the Gero Gero Gun and Yellow Gun. There was a blast mode which was disabled. I have re-enabled so you should have more fire power for a small amount of time," Emeraude said.

"Wow," Vivi said. 

"That sounds handy," Marianne said.

"It will be, there are some more modifications we can make but it will take some time," Rubis added.

"Those are my sisters," Saphir said.

"Excellent job," Ben said. The girls clapped and cheered. Mikita whistled. 

Emeraude handed the Gero Gero gun to Vivi. Mikita took the Yellow Gun.

"Just in case," Mikita said. Ben nodded. 

"Okay, besides Rubis, Emeraude and Saphir everyone will head to the island. Our main objective is to secure another orb," Ben said. 

The girls cheered. "Okay, Zala, Robin you can fly with me," Ben said.

"Kaya, can you take Vivi and Nojiko?" Ben asked.

"Sure," Kaya replied. The girls high-five each other. 

"HQ can you fly Alvida and Mikita over?" Ben asked.

"Yes Master," HQ replied.

"The rest will go on Lexie with BM," Ben said.

They nodded. "It will not be uncomfortable for once," Marianne said.

"But I like you sitting on my lap," Honey said.

"I do as well," Ben added. Marianne smiled. 

"Let's go," Ben said. The girls nodded. 

They made their way to the deck. Ben transformed into his hybrid form. Kaya transformed into her beast form. Vivi looked a bit saddened at her transformation . Ben noticed this. "Don't worry Vivi, you will be able to do it soon," Ben reassured her. 

Vivi smiled and nodded. Zala and Robin held Ben. Ben held them by their waist.

"Bold," Robin said.

"Very bold," Zala added.

"Sorry," Ben said as he was about to move his hand away when they both stopped him.

"Does not mean we do not like it," Zala said. Robin smiled. Zala whispered in Ben`s ear, "It's my turn today. I can't wait." 

Ben smiled. He flew up in the air towards the island.
