Two figures can be seen in the middle of a forest, one of them was fighting a small group of No Ranked Beast which consists of 10 snakes, and the little pink lizard was gasping for air. If someone saw this they can tell that she is having a hard time. While the other one is just watching her suffer with a smirk on her face, she then giggled and said.
"Yumie if you can't even fight this, how do you expect to fight some Savage Beast!?" Yuki said.
[But Big Sister this is too difficult! They are a group while I'm alone; this is not fair.] Yumie argued with Yuki.
"No, this is good training for you Yumie!" Yuki said while looking at Yumie with a sadistic smile. When Yumie saw Yuki's smile she shivered in fright and gulped, she then said to herself [Big Sister is right how can I get stronger if I can't even fight this? But Big Sister Yuki's smile is scary. She's like a completely different person.]
Yumie was right about this. Yuki has a sadistic side to her when she trains a person. Since Yuki wants the best for the person that she is training, she will put cruel training for that, Yuki also likes people suffering when she trains them that's why Yumie was currently scared of Yuki right now.
In her past life, a lot of people also got a taste of Yuki's sadistic side when she was still the CEO of her company. She liked to see her staff suffer when they were working so she purposely set up hard work for them. But in the end, it was worth it since they are the best company in the whole of Japan after that.
Back to the present. While Yumie was still fighting all of the snakes Yuki saw that Yumie sometimes hesitated to kill them. She will only kill them if she gets hit by them and under no circumstances that she will kill them, Yuki saw that Yumie is a kid little girl but this can also be her downfall so she set up something new for her.
"Wait Yumie stop!" After saying that Yuki then unleashed some Ice Chains and wrapped the snakes with them.
Yumie was confused but did not ask since she knew that her Big Sister Yuki knows what she is doing.
"Yumie I saw that you were hesitant to kill them or even hit them. Why is that?"
Yuki asked Yumie.
[Big Sister... The reason is I don't want to see them hurt even though they are an enemy.] Yumie answered while lowering her head and trying not to meet Yuki's gaze.
"This is the first problem that you have to do. You need to kill them without hesitating. If you can't do this you can't get strong." Yuki said in a stern voice.
[But... Ok Big Sister I'll try.]
"Very good. Now I already immobilized them so you only need to hit them once and it's done."
Yumie was still hesitating to kill them but once she remembered Yuki's word that the strong eat the weak she steeled her mind and raised her tail to slash them.
Yumie then closed her eyes to focus and once she was ready she opened them, her eyes did not look like little girls anymore but a strong ones. She was now ready to kill for the first time in her life. After that Yumie slashed the one that was the closest to her, the head of the snake then fell to the ground and rolled towards Yumie.
When Yumie saw this her tears started to come down, she was now scared. This was her first time killing so she was still not used to this. Yuki who saw this immediately went for a hug to calm Yumie down.
Yuki knew that this was hard for Yumie but she knew that Yumie needs to do this or she will never grow up.
[Big Sister Sob...]
"Shush you don't need to say anything just calm down for now. I know that this is hard for you but you need to brace yourself since you will kill your enemies once you grow up." Yuki said while patting Yumie's head.
Yumie just nodded at her and tried to calm herself down, she didn't want Yuki to see her weakness anymore. A few minutes later Yumie calmed down and looked at the other snakes that were still fighting to break out of the chains.
When Yuki saw this she nodded and smiled at her and said: "Now that you've calmed down kill all of them then will try to look for more In Ranked Beast for you to fight."
[Ok Big Sister.] After Yumie says that to Yuki she looked at the snakes and killed all of them in an instant. She was now feeling proud since she is not scared anymore to kill her enemies without having mercy.
Yumie learned that being kind was good but being too kind was also bad since her enemies can use this to manipulate her.
Yuki was now feeling proud like a true Big Sister while looking at the back of Yumie who just killed her enemies in one go. She then rushed to Yumie's side and hugged her again and said.
"Well done! I'm so proud of you right now Yumie, now that you can fight them without hesitating it's time to get serious now." Yuki was now back at her being a sadist in training, when Yumie saw this she shivered at this while looking at Yuki's fearful smile.
[Big Sister isn't this enough for now? and it's already night time can't we just rest for now?] Yumie said while trying to run away from Yuki. But alas she was too late. Yuki had already grabbed her and tossed her to an army of snakes again but this time the number doubled.
[Ahhh Big Sister you're so cruel to me.] Yukie said while running away from them.
"Hehehe Yumie the night is still long. You need to finish in under 10 minutes. If you don't then I will make it harder next time!"
