When Haru and Astarte disappeared, Himeragi knew that he was using his teleportation ability, but because of that, she was quite panicked since she didn't know where he was. However, she knew that he had gone to help Astarte, which was why she regretted that she couldn't do anything in this situation, which somehow made her depressed.
When Himeragi didn't know what to do, she heard a familiar voice.
'Just come inside the house and I'll take care of Astarte for a bit.'
Himeragi heard a voice on her head, which made her dumbfounded, and she quickly asked, "Senpai, where are you?" She asked that question, but he didn't answer her, which somehow made her depressed and sad. However, she followed her words and entered the house, waiting for him since she knew that it was the only thing that she could do now.
---
Shishio teleported to the guest room inside his house then put Astarte on the bed.
"Cough!"
Astarte coughed up other blood, but her complexion was quite better now since Haru had been using his light magic to heal her. "Kasugano-sama..." She looked at him, who had helped her, and felt very grateful toward him, even though their meeting was very short. If possible, she wanted to serve him more, but she knew that she couldn't live too long, considering the familiar inside her body kept eating her life force.
Haru gently caressed Astarte's head and said, "Don't worry, you'll be alright."
"Umm..." Astarte nodded and closed her eyes. Her entire body was quite painful before, but slowly it became better being treated by Haru.
Haru used his "Elemental Sight" again and wondered what he should do with Astarte. He knew that Astarte was a homunculus, and somehow she reminded him of Sieg, who he met in the world of Fate/Apocrypha.
Similar to humans, homunculus had a limited age, but their age was shorter than humans.
If Haru wasn't wrong, he remembered that Sieg could only live for three years, but because the life force on his body was absorbed and was used to supply the magic for the servants of the Black Faction, Sieg's age was even shorter.
The reason Sieg could live so long was that Siegfried had his heart to Sieg and let Sieg live for a long time.
There was no way Haru could get the heart of someone for Astarte, and there was also no way for him to summon a servant so they would become sacrifices for Astarte even though he had a Holy Grail inside his body.
Haru knew the reason why Astarte couldn't live so long was because of the familiar inside her body.
The reason why the familiar decided to follow a vampire was that a vampire had an unlimited life force and that life force was the feed of the familiar.
However, the homunculus was different, and there was no way that they could feed an insatiable beast inside their bodies.
If it was before, Haru might have had trouble helping Astarte. Even though he was powerful, there was no way for him to extend someone else's lifespan. If it was energy, then it was possible, but energy and lifespan were two different things.
However, it was different now since he had developed his "Snatch" ability very well, and it was also the reason why his women readily agreed to lend him their powers. The reason for that was because of one of the techniques of his "Snatch" ability, which was "Gift."
"Gift" was an ability that Haru had developed to counter his "Snatch." If his "Snatch" was to give, then "Gift" was to give. In the story of Nanatsu no Taizai, Ban was able to develop "Snatch," but as usual, the way he used it was very crude since he could only use it to transfer his own life force and strength to another being. However, in Haru's hand, this ability was blooming to the fullest since he could give various abilities or talents or even something conceptual such as luck to someone.
It was simply an amazing power, and combined with his "Snatch," Haru was simply an existence of a bug in this world. However, he knew this ability was powerful. It wasn't omnipotent since the speed of his "Snatch" couldn't be done in an instant, and if someone could defeat him at a very fast speed, then he was as good as done for.
Haru knew that he was very powerful, but it didn't mean he was the strongest.
His energy might be huge, but it didn't mean he had immortality. He was human, after all. However, he might live a very long life since he was very strong.
'But...'
Haru had become a vampire now, and he had an unlimited amount of life energy, so he directly transferred it to Astarte's body. He could see that her complexion had gotten better and better, and using his "Elemental Sight," he knew that he had added her lifespan, which somehow made him sigh in relief.
'However...'
Haru thought about the existence of the familiar inside Astarte's body, and he had to admit that it was quite troublesome. He could steal it directly, but he felt that it would weaken her power, which made him a bit hesitant. He thought for a while and remembered his vampire ability, which made him capable of subduing any familiar easily since, with his status as a fourth primogenitor, there wouldn't be any familiars that would reject him.
'But...'
Haru thought of how he needed to use this ability and couldn't help but let out a sigh.
'Well, let's do this.'
Haru then unsealed one of his vampiric abilities, and the fangs on his mouth became slightly longer and sharper. Then without hesitation, he bit Astarte's neck, which caused her to let out a moan, and directly used his ability to subdue the familiars inside her body. He didn't forget to use a "Pleasure Magic" on the tip of his fangs so it wouldn't cause her to be in pain.
Haru wasn't sure about biting people on the neck, but he knew that it was quite painful for the people who were bitten, so he used his "Pleasure Magic" so it wouldn't cause Astarte to be in pain.
The process was instant, and he quickly detached his fangs away before he sealed his urge again with his seal magic.
Haru then checked Astarte's condition for a while and helped her so her condition wouldn't relapse and became better until he saw everything was alright. When everything ended, he sighed in relief before he let her sleep. As for what he was doing with her after this?
Haru was an older brother, and he was also a gentleman, but he wasn't a lolicon, so he let her sleep on the bed directly, waiting until tomorrow when she woke up. Then without hesitation, he opened the door and saw Himeragi and Natsuki were there. He looked at Natsuki and asked, "Is your matter done?"
"Yes." Natsuki nodded and asked, "What about that little girl?"
"Well, she's alright now. Do you want to have the same room as her?" Natsuki asked.
Natsuki thought for a while and shook her head. "No, can you lead me to my room?"
Haru then looked at a lot of suitcases behind Natsuki, and his lips twitched since the amount was so huge. He even saw a princess size bed in the corridor of his house, which made him speechless.
Natsuki noticed his gaze, blushed, and quickly said, "I can't sleep on the futon."
Haru nodded and didn't say much. "Well, Himeragi, can you sleep first? I'm sure that you're tired after what has happened today."
"Yes, Senpai." Himeragi nodded since, in truth, she was really tired.
Haru looked at Himeragi's complexion, then looked at her spear, but in the end, he didn't say anything. "I'll talk with Natsuki-chan first."
"Don't call me Natsuki-chan!" Natsuki quickly reacted. Even though she didn't mind being called "-chan" by him, it might be her reflex to say so.
"Shh... don't be too loud, you'll wake her up," Haru said and closed the door. "Come on, Natsuki-chan. The faster you set up your luggage, the faster I can sleep."
"Don't call me, Natsuki-chan!" Natsuki retorted.
Looking at how close they were, Himeragi wasn't sure why, but she felt a bit bitter, and at the same time, there was a bit of regret since she couldn't know him earlier. 'No! No! Himeragi, you're his observer! You can't think this way!' She then quickly ran into her room since she needed to reflect on herself, especially when she recalled when he held her hand and hugged her waist. Rather than hating it, she felt that her heart skipped excitedly.
