The two new sisters then began to travel back to Yuki's original cave, since Yuki forgot that the egg was still there all alone Yuki just carried Yumie so the travel will be much faster.
When they are finally outside the cave Yumie asked Yuki [Big Sister, did you make this Ice Wall? and who are you protecting here?] Yuki then put down Yumie and answered "Yes I made this wall because there is someone important living here that I am guarding."
As Yuki answered Yumie she began to make a little hole so that both she and Yumie would fit since Yuki doesn't want to destroy the wall and make another one when she goes out.
Yumie understood what Yuki meant so she just nodded her little head and began to look around the cave after entering with Yuki. She found that there was nothing there other than a big blue egg that was playing on the ground.
Yumie got confused since her cave was pretty much better than Yuki's because at least she has a decent bed to sleep in. So she decided to ask Yuki [Big Sister don't you have a bed?, and Is the egg the one you're trying to protect?]
"Yes, it is the one." Yuki nodded her head in response.
[But isn't Big Sister a fox so why does she have an egg?] Yumie asked curiously.
"HAHAHA! Yes, I'm a fox but that egg will be my adopted daughter and you will be my adopted sister. Do you not want that?" Yuki chuckled and asked Yumie.
[Of course I- I want to be a little sister because Big Sister Yuki is from those bad guys.]
"Oh yes, why do they want to kill you? I saw that they even get a giant army just for you?"
Yumie smiled bitterly and said [That's because they think that I'm a disgrace to their race since I'm different from them. I was weak and a coward not like them. They are big, strong, and prideful.] Yumie then looked at the ground with teary eyes and asked Yuki [Big Sister are you gonna abandon me since you now know that I'm weak and a coward?]
When Yuki heard Yumie she immediately hugged her and said [Of course not! Your going to be my Little Sister now if anyone dares to bully you I'll kill them without a single thought!" Yuki then reassured her that she will not leave Yumie alone.
[Thank you Big Sister!] Yumie then hugged back Yuki.
"But why is it that you are different from them? I can see that you are small." Yuki asked.
[Big Sister I don't know but when I was born my mother sent me to their tribe when I was born, my mother left me a note that I'm different from those lizards and said that live a good life and sorry that she cannot accompany me when I grow up. The letter also said that my father left my mother when he received the news that my mother is pregnant.] Yumie then began to remember her mother's face.
Yuki who heard Yumie's story was now extremely mad at her father and began to curse "F*ck this is what I hate the most about leaving responsibilities!" She then remembered that her life was similar to Yumie's growing up she was looked down on from birth.
Remembering her past Yuki cannot help herself from hugging Yumie even tighter and saying "Don't worry I'm your family now I will never leave you."
Yumie then nodded her head and said [Big Sister, can you help me to get stronger since I don't want to be a burden to you.]
"Why do you want to be strong? You know that I can always protect you?" Yuki asked
[No Big Sister I don't always want to rely on you. I also want to get strong so that in the future, I can also protect you and that egg.] Yumie said with a burning passion.
Yuki chuckled and said to herself 'Yeah, keeping her and always protecting her will do more harm than good since I already experienced that. Plus being stronger is good since this world is a cruel one where the strong prey on the weak.'
"Ok that's not a problem but the training will be a hard one. Can you handle it?" Yuki smirked and asked Yumie.
[Yes no matter how hard it is I will do it!] Yumie answered Yuki.
"Good. We will start tomorrow now get some more rest."
Yumie just nod and began to walk away.
When Yumie was gone Yuki decided to ask Fubuki a question "Fubuki how can I make her stronger? Can I let her learn some skills from the shop?"
Ding
[No since the entity Yumie is not a part of the system she does not have any access to it.]
Yuki frowned and asked another question "But how about that egg since you gave it to me?"
[No it was just a reward that the system randomly gave.]
"Too bad. Oh well, I don't have any choice. But Yuki, do you have any suggestions on how to make Yumie and the egg stronger?"
[No, the host just needs to teach them some combat moves and let them evolve by themselves since they have a strong bloodline.]
"I get it now thank you."
The next day quickly passed, after talking to Fubuki more, Yuki now knew what she should do to Yumie.
Yuki decided that she would teach Yumie how to fight first, but when they were about to fight Yuki stopped and looked at Yumie.
"Yumie I think let's control your emotions first. Don't be scared when fighting and just stay calm even though you are losing." Yuki just now understands that what Yumie needs to do first is to erase her scared feeling when she is fighting.
[But Big Sister, how do I do it? When I was in the lizard race for a few days they disgusted me so I felt that I'm always weaker.] Yumie then smiled bitterly.
"No problem. You must remember that you're a Hydra and not a lizard so have more confidence in yourself. But don't underestimate your enemies." Yuki then advised Yumie.
"Also always remember this even though I already said it's the most important to be CALM don't show any weaknesses when fighting, and don't back down unless you need to," Yuki added
[I understand Big Sister, I will try my best!] Yumie was now very excited but little did she know that her training will be a cruel one.
