Yale was thinking that after hearing the woman's words.
"Sorry, I forgot to introduce myself. I am Aiwai, a 9-star Master with a Frost Winged Wolf bloodline."
The Master Rank was the Rank 6, and as she was at the 9-star, she was almost at the Rank 7. Of course, making that breakthrough was difficult, but as she still looked young, Yale believed that she would reach it someday.
"I am Yale, and she is my little sister Wyba."
Yale introduced himself and Wyba politely, Aiwai seemed to be kind, but with her power, it was better to don't make her angry.
"I sense that your bloodlines are still rather undeveloped, you two are still too young after all. If your bloodlines were at their peak, I would have detected you before."
It wasn't weird for kids with too powerful bloodlines to develop the bloodlines slowly as the half-beast growth, that was to reduce the effects on the body as a little kid would have problems controlling a big amount of power.
The reason why Wyba didn't advance even if she wasn't restricted was due to a similar reason; it wasn't strange that Aiwai thought that.
However, even if she was able to see through Yale's real age, that wasn't an age to have an undeveloped bloodline.
"Well, I have the same bloodline as Wyba, so she should have also identified it as undeveloped."
Wyba and Yale didn't have undeveloped bloodlines; their bloodlines were in a developed state. However, Yale understood that thinking they had undeveloped bloodlines was more normal than discovering the truth about how both of them improved their bloodlines.
Furthermore, the only reason she was able to detect that much was that they had the same bloodline and she was overly sensitive to it.
Yale was still immersed in his thoughts when Aiwai continued.
"I came here to adopt both of you as my younger brother and my younger sister. I have never met anyone else who had my bloodline, and I lived alone a lot of time. Both of you are too young compared with me, so I can also adopt you like your mother, but I don't want to be disrespectful with your real mother, so as siblings is still alright."
Aiwai said that for formality, but she thought that they hated their parents and being a mother would be something negative to them. She was thinking that Yale and Wyba had been rejected by others with the Frost Wolf bloodline due to being different.
That had happened to her when she was young, her bloodline was mutated, and she was far stronger than the others, so everyone feared her. They didn't expel her from the town, but she was tired of being seen as a weird phenomenon, and she decided to leave alone.
In such bloodline mutation cases, the firsts in treating you bad were the parents. They didn't show love for mutated bloodline kids; they only urge them to turn strong, grow and had a lot of kids.
Most half-beasts in that situation, being treated as objects to strengthen their clans, chose to leave as long they were powerful enough.
Aiwai never had friends or people who she considered family; the bloodlines were too important to half-beasts, only those with the same bloodline were capable of being truly close to each other.
Aiwai had given up making friends with other bloodlines as most of them only feared her, but when she smelled for the first time two people with the same bloodline as her, she rushed to meet them.
Yale and Wyba weren't real half-beasts nor had such story, but it was true that both of them didn't know anything about parental love and Yale didn't sense any belonging to the clans of his parents.
Wyba was about to start crying as she was remembering her mother about who she didn't remember anything besides she died to save her.
"Don't be sad. She did anything bad to you?"
At that moment, Yale was guessing that Aiwa had a wrong impression about Wyba's mother, so he explained to her.
"She died saving our lives when she was weak after giving birth. She managed to save us, but she died afterward due to the injuries of that day."
Aiwai was surprised by that; she didn't know if she did it because she didn't notice the mutation or they had a really good mother. Evidently, although Yale was speaking about Wyba's mother, Aiwa considered her the mother of both.
"Her husband didn't help her?"
Disregarding the truth, Aiwa was touched by that story.
"You can't call him husband, that beast had too many women it wasn't like he cared about one, he fled immediately abandoning her at the sight of danger."
Aiwai sighed, that was a more normal behavior although despicable. Calling beast a half-beast was a great insult; since Yale called that to his father, Aiwai understood that at the end they also had a rough childhood.
Yale was calling beast a beast, but he thought the same of his own father.
"You fled from him and started traveling?"
Yale laughed while remembering that scene from the past.
"I killed him."
Aiwai understood that although Yale was laughing, he wasn't joking. Aiwai didn't kill anyone when she left, but sometimes the clans try to block the half-beasts with a mutated bloodline from leaving, and some clans had even disappeared due to that in the long story of the Anpaes Kingdom.
"I am surprised how quickly you managed to survive by yourselves; you should have had a tough life after your birth to make you leave at such a young age. But don't worry, from today on, I am your big sister and anyone who dares to harm you would end like those bandits. How they dare to aim at you. If I weren't in a rush to kill them and was that far I would have killed them in a more painful way."
In the end, Yale had decided to accept Aiwai as a big sister for two main reasons.
The first, even if he said no, she could take them by force if she wanted, it was better to be his little brother willingly and probably he and Wyba would be able to benefit greatly.
The second reason was even more important to Yale. Aiwai was without doubts someone who can teach him archery. Yale felt that her archery wasn't worse than Swordmad's swordsmanship even if her realm was still a bit lower than him.
Aiwai neared Wyba and hugged her until she stopped her tears, she had been unable to stop them after thinking about her mother.
While she was hugging Wyba, she spoke to Yale with her Spiritual Sense.
"Why don't you turn back to your real form? I understand that you learned a skill to look older for your security while traveling, but now you don't need to worry about anything."
Yale was scared to death with the first part of the sentence, but he relaxed after hearing the next part. Aiwai only discovered that he looked older than his real age and not that he wasn't a half-beast. Yale didn't look older due to a skill, but he didn't want to give more details to Aiwai.
"It's really weird for a kid with four years old to look that old; you should turn to your real size. I am sure you will be really cute even if you are a boy, you are Wyba's twin after all."
At that moment Yale was shocked, and his mind was thinking at top speed.
"Wait! I would have understood if she wanted me to have a height of an ordinary thirteen years old boy. No, she thinks I have an undeveloped bloodline, so she should have thought I am younger than that, but why exactly the same age as Wyba and her twin?"
After thinking a bit more, Yale finally found the reason.
"Our bloodlines are completely identical. Even being normal siblings that would be too much coincidence. Furthermore, we have both the same mutated bloodline and the same grade of bloodline development based on her impression. Thinking from her point of view, it would be weird if I wasn't Wyba's twin."
The mutation of bloodlines was really strange and good mutations even more; if both siblings had the same, the only reasons should be that they were twins or that their parents had a heaven-defying luck.
"My real age is a secret to the people of this town; I can't transform here. Furthermore, I feel used to my current height, is really necessary to change it?"
Yale was at his real height, but he knew that there was no way Aiwa would believe it, so he just wanted to convince her to avoid changing his size.
Of course, Yale was replying to her with his Spiritual Sense; he didn't want to say those words aloud.
If Aiwai wanted to misunderstand his real age, then it was alright as she was incredibly powerful compared to him, but Yale didn't want that the people in the town also thought that he was a little kid comparable to Wyba.
