"...."
Bourne was speechless by this question, but then someone came to help him.
Erza Knightwalker with her maid uniform came and brought a set of tea and cookies to the living room.
"..."
Mirajane, Lisanna, and Elfman opened their mouths and eyes wide when they saw Erza Knightwalker since the appearance of Erza Knightwalker was very similar to Erza Scarlet, and knowing Erza Scarlet, they wouldn't think that someone as tough as her would do this kind of things which caused them to feel uncomfortable.
"Thank you, Erza," Bourne said with a smile.
Erza blushed and nodded. She winked, waiting for him before leaving them, thinking that they might have something to say.
"...."
Bourne shook his head and sipped the tea which was prepared by Erza calmly, but he almost spat out since it tasted so weird. He then looked at Erza who was smiling at him, thinking that this girl was waiting for him to punish her again. He put down the cup of tea and changed the tea into mineral water with his magic. He wanted to say something, but before he said it, Elfman asked him a question first.
"Is that Erza from Edolas?" Elfman asked.
"Yes." Bourne smiled and said, "Well, the time on the Edolas was quite short so I didn't see your counterpart there Elfman, but I am sure that Lisa is happy when she has returned to their siblings there and I am also sure that both Elfman and Mira in Edolas are also happy when their little sister returns to them."
"..."
Mirajane, Lisanna, and Elfman felt a bit down when they heard it, even though Lisa was from Edolas, and might not be their siblings in this world, but they thought of her as their siblings after all and they had been living together for several years.
Lisa had gone back to her original world, but Strauss' siblings hadn't even said goodbye to her when she parted and that was why they decided to come to Bourne's house, wondering whether Lisa had entrusted him with something since they heard from Erza Scarlet that Bourne wasn't affected by Edolas's "Anima".
Unlike Elfman who was oblivious, when Lisanna and Mirajane heard that matter from Erza Scarlet, they knew that something must have happened between Bourne and Lisa since Erza Scarlet's expression was quite weird when she told them about Lisa's matter as if she tried to hide something?
Well, the matter of Erza Knightwalker was one thing since even the people from the Fairy Tail were also amazed when they heard that the counterpart of Erza Scarlet decided to come to Earthland, of course, they wanted to see Erza Knightwalker, but the problem was Erza Knightwalker was Bourne's woman which made them impossible to see her, considering how bad the relationship between Bourne and Fairy Tail as long as Gray was in that guild.
It might not be related to the previous sentence, but they had never thought to throw Gray away, even though the problem had been caused by him to their guild and Makarov also wouldn't let Gray go even though Gray wanted to exit from the guild since he knew that he had caused a problem for everyone.
However, none of that really mattered to Bourne since he didn't care anymore about Gray since Gray's existence was only a small matter in his life, and he didn't think too much as long as he didn't see him.
Bourne then took something out of his "water storage" for them and said, "This is a letter from Lisa."
Without hesitation, Mirajane, Lisanna, and Elfman took the letter from Bourne's hand.
Bourne, on the other hand, sat while looking at their expressions.
"Men...."
Before long Elfman cried loudly when he read the letter which was entrusted to Bourne by Lisa.
The content of the letter was pretty simple and that was how grateful Lisa was to the Mirajane, Lisanna, and Elfman in the Earthland and how happy she was when she stayed with them, lastly, at how she had always thought of them as their siblings even if they were from different worlds.
Even Lisanna and Mirajane couldn't control their tears when they read the letter.
Elfman couldn't handle it anymore and drank the tea which was prepared by Erza Knightwalker.
Bourne was startled and wanted to remind Elfman, but he was too late.
Elfman's expression changed slightly, but he kept drinking the tea. "It.. It's bitter..."
Yes, it was so bitter for the Strauss siblings since they couldn't even say goodbye to Lisa.
"Has Lisa said anything to you, Bourne-nii?" Lisanna asked.
"...Why did you call me big brother?" Bourne looked at Lisanna with a weird expression.
Lisanna chuckled and didn't answer Bourne's question , on the other hand, Mirajane glared at Lisanna.
Lisanna didn't say anything, but she felt slightly bitter since the three women on Strauss' siblings knew each other feelings, but Mirajane's feeling was stronger than both Lisanna and Lisa.
Elfman didn't care what they were talking about, only crying loudly since he knew that he wouldn't be able to see Lisa in the future anymore since they were separated by a different world, but then he realized something and asked, "Bourne, can we... can we meet Lisa in the future?"
"......"
Lisanna and Mirajane also looked at Bourne at the same time.
There was no way that they wanted to stay like this, they loved Lisa and they wanted to meet her again, however they knew how difficult it was, considering they were in Earthland and Lisa was in Edolas, but the guy in front of them was a genius and the richest man in the continent so he should have a way, right?
"Space is a mysterious thing. If you use a space magic carelessly, you might be transferred into nothingness where there is nothing there..."
"Then..."
The three Strauss siblings became depressed when they thought that they were unable to meet Lisa again in the future.
"But as long as there is a mark that can lead us to Edolas then it might be possible to visit Lisa," Bourne said.
"What?!"
Lisa, Mirajane, and Elfman were startled.
"Is there something related to Lisa's? Well, it can be anything, probably, if you have it then it might be possible to go to Edolas," Bourne said.
"I will go back to see whether there's something or not!" Elfman didn't wait for anyone and quickly ran as fast as possible to go home, wondering whether there was something that was related to Lisa.
"Elfman! Wait for me!" Mirajane was about to chase after Elfman, but she was stopped by Lisanna.
"Mira-nee, you should wait here. I will come with Elf-nii," Lisanna said.
"What?"
Mirajane was confused, but she was forced to sit down. Then her eyes happened to meet Bourne's. She then stared at him and asked, "Have you kissed Lisa?" She asked this question again since she had heard from Erza Scarlet that both Bourne and Lisa had kissed each other.
"......"
Bourne was speechless and asked, "Do you want to walk outside to talk?"
