Out of all of girls, Rias was the only one who was aware that Rebecca wasn't Rudy's biological mother. Sure, Lilim also knew, but she wasn't present there. And Angelica was the only one who was aware of Rudy's feelings toward Rebecca.
Rias wanted to comment something after hearing that, but she decided to stay quiet until she learned more about Rebecca and who she truly was.
"Alright. So I will take my leave now. See you all in the morning. And... yeah! I will bring Alice too. I messaged her a while ago, but she never replied, so she is most likely sleeping since it's already past midnight."
Rudy grabbed Reina and said, "I will drop her at the office."
He teleported to Reina's office with Reina and let out a weary sigh.
"Alright then, Reina. I will see you tomorrow, and don't forget to call me when the builder comes."
"Hmm," Reina nodded. But she suddenly wrapped her hands around Rudy's neck and missed him a few times before saying, "Are we not going to have sex? It's been a while since we last had some fun together."
"The vampire gang is here."
"So?"
Rudy squinted his eyes and squeezed Reina's breasts as he asked, "Did you forget what I told you about?"
"I remember."
"Repeat it."
"All the girls know that you have a harem. Jane, Niti, and Rias know that you are in a relationship with them. Niti knows about Jane and Rias. Rias knows about Jane and Niti. But Jane doesn't know about Niti and is also unaware that Rias already knows everything," Reina repeated Rudy's words.
"Nice."
"And I will not mention anything about harem in front of Jane when Rias is around."
"Good."
"So, where is my reward now?"
Rudy looked at the time and muttered, "I guess we can have some fun."
Rudy returned to the vampire gang after forty minutes. The girls had already made themselves comfortable, and they hadn't expected Rudy to return.
"Hey, Jane. Can you come with me for a while? Since you have vampire powers, I should show you the areas you shouldn't go as they are under surveillance."
"Okay."
Rudy and Jane left, and after showing her around, they went to an alley because Jane wanted to go there.
"What's wrong? An alley is not a safe place for girls, you know?" he remarked with a grin, knowing well that Jane could effortlessly obliterate anyone.
Jane pushed Rudy against the wall and said, "I want mister dick! It's been so long!"
"Oh! Yeah, I should have expected this."
Rudy and Jane returned to the vampire gang after thirty minutes of 'rough' exploration.
"Niti, let me tell you your duties," Rudy called her out.
After telling her about some things about the human world, they went to the locker room of the pool, where Rudy 'mined' Niti's cave for half an hour.
When they returned to the vampire gang, Rias was waiting for her turn.
"Rias, can you come with me for a while? I want to talk to you," he asked calmly.
Unlike other girls, Rudy could invite her without any worries as her relationship with Rudy was official between the harem members.
Rudy took Rias to a nearby forest where no one was around. There he found the tallest tree, and they sat on the highest branch of the tree.
Rudy was leaning toward the trunk while Rias was leaning on Rudy. They were cuddling with each other while looking at the beautiful starry sky.
"It's so beautiful..." Rias uttered while gazing at the full white moon.
"You are more beautiful."
"Geh! Don't use these cliche lines on me."
"Heh!" He kissed her on the cheek and said, "Do you like this world?"
"Obviously. What's there to not like?"
"Well... there are actually many things, but let's not talk about it." Rudy hugged her tightly from behind and closed his eyes.
"What happened to the 'mother matter' you were talking about?" Rias asked curiously.
"I can do that after a little while. She is currently working the night shift at the convenience store, so she will be there till the morning," he said in a low voice.
Rias lowered her gaze from the sky and glanced around at the forest and far away city. She could see tall buildings and lights and hear the cars racing on the highway streets.
The cold breeze passed through the woods, making a howling-like sound as it swayed the tree leaves and spread the smell of fruits and flowers from the nearby farms.
Even though it was past midnight, there were people busy with their work and life. Whether they were enjoying it was a different matter, but looking at them made Rias chuckle a little.
"This is what I love about the human world. Knowing that we are not the only ones awake at this time calms me down for some reason."
Rudy's eyes were still closed, and he was enjoying Rias' embrace. For him, sitting like that with Rias calmed him down.
A few minutes later, Rias finally gathered her courage and asked, "Why did you stop me?"
"Hmm?" Rudy reacted with his eyes still closed.
"I wanted to ask something to Angelica, but you stopped me on purpose and then changed the topic. Do you not want her to find out about herself?"
Rudy slowly opened his eyes and rested his head on Rias' shoulders.
"I am scared."
"Of what?"
"Of losing her."
After a brief silence, Rudy uttered, "Whenever I had free time, I went to search more about Angelica. She died eight years ago; that is in the year 2000. The internet was still a thing at that time, but it wasn't that widely known for news and blogs.
I am not trying to claim anything, but I am saying this based on the non-existent information I got. I can hack into any database, but I couldn't find anything related to Angelica.
Not. A. Thing. Nothing... at all."
