Six months isn't a short time, but it isn't a very long time either.
During his observation days, K-423 discovers that the honkai energy around their home is starting to increase little by little.
The Honkai beasts kept appearing one after another, and Kiana, who had the true soul of Kaslana, started to exterminate the Honkai beasts every day.
Since Siegfried was disabled and immobile for the whole day after training in ICHOR mode. Kiana is the one who takes on his duties as a protector of the weak for those who live in the area around where she lives.
With a pistol Siegfried had given him in the her birthday. Kiana fights against the Honkai beasts every day, and her reputation as a "little angel" begins to spread across various villages, and small ruined towns.
Now, at this time the hero that was being admired by many people had just finished exterminating a group of Honkai beasts, and she looked at the dead body honkai beasts with curious eyes.
"Another me, have you ever thought about eating the flesh of a Honkai beast?"
"[Good idea Kiana. Now let's go home.]"
"Muuu... You always ignore my opinion like this. What's wrong if we try something new every once in a while?"
"[The meat of the Honkai beast is not good...]"
"How did you know!? You ate it behind my back secretly?!"
"[....]"
"Come on, just this one time, Please~"
K-423 took a deep breath: "[The last time you said this exact thing was when you ate stale cheese in the fridge a month ago! What was the result? You were dying for the whole day Kiana!!]"
"[Who comes to me for a hug, and whines that her stomach hurts so bad!?]"
"Cough! Cough! Cough!"
Kiana coughed, and she choked on her own saliva. Her baby face turned red very quickly.
"T-That doesn't count! Look, these Honkai beasts I just killed, they're fresh stuff! As long as we roast them thoroughly, we can eat them!"
"[Oh really, Why does it feel so unconvincing?]"
"Ahem! If we haven't tried it, how can we know."
In the main plot, when Kiana is wandering around and runs out of food. She once ate the meat of a Honkai beast because she was too hungry at that time.
If an ordinary person, and a valkyrie eat the flesh of a Honkai beast, then that person will die from the corrosion of the Honkai energy. But with special conditions like Kiana who carries the Herrscher of Void's core in her body, it's not completely certain.
K-423 only felt that Kiana's current behavior was of no use at all.
But....
"...I was just curious."
When she saw that Kiana gradually lost her enthusiasm, and kicked a small rock on the road in annoyance. K-423 could only let out another long sigh.
It seemed like the adult memory she had were curbing the enthusiastic behavior of a child.
K-423 realizes something is wrong with her thinking.
The reason why young children are happier than adults is because they don't think to much about they consequences. The more stupid a person is, the happier she will be.
K-423 realizes that adult thinking curbs her childish behavior. This must be changed.
After all, she was still only ten years old now. She didn't want to enter the circle of adults, and feel tormented like them.
Her childhood is still long.
"[It's up to you Kiana. But I suggest, don't eat it too much.]"
"Really? Really!?!"
Kiana's eyes lit up with great joy.
According to Kiana, her other self is very talkative when she is doing things that are beyond the limits of normal people's thinking in general. Why was her other self suddenly agreeing with him?
"[Early warning, stomach pain is at your own risk. I will not replace you when you need to go to the toilet.]"
"No problem, I'm Kiana Kaslana, not afraid of pain! I have an iron stomach!"
Kiana smiled proudly.

In the night....
After Kiana exterminated the Honkai beasts and went out to play for a whole day. She returned home in the afternoon, and waited for Siegfried to prepare food.
Because Siegfried always deactivated in the morning and afternoon. He now took over the chores of making dinner, trying to maintain his dignity as the head of the family.
Siegfried's cooking are also growing day by day. From inedible, to dishes that have a normal taste.
A person turns out to be able to change if he wants to.
That's what K-423 learns when she watches the evolution of Siegfried's cooking every day.
"Kiana, it's time for dinner!"
Put warm chicken soup into a bowl. Siegfried tidied up the dining table, and he nodded his head in satisfaction.
"Strange, why is it so quiet?"
Siegfried found that something was wrong.
Usually when it's time to eat, Kiana will run to the kitchen very quickly, and she always makes a scene everywhere.
This kind of lonely and desolate feeling made Siegfried feel very strange.
"Kiana?"
Found that Kiana was lying on the sofa, clutching her stomach in pain, and at the same time cold sweat. Siegfried who saw that her lips were pale in color, suddenly panicked.
"What's wrong Kiana?! Is something wrong? Did you get food poisoning again!?"
"...."
Kiana just stared at Siegfried with an angry, irritated look, and was filled with a very strong sense of helplessness.
Her stomach hurt so much, that she didn't want to open her eyes at all.
Closing her mouth tightly, Kiana suffered silently with occasional small whimpers escaping from her mouth.
"[You idiot, I knew this would happen.]"
Making Kiana faint, and dragging her into the stigma room. K-423, who shared half the pain, frowned.
She different from her who can break the physical sensory connection when she enters the stigma space. Kiana who has a body, even if she enters the space of stigma, the pain in her body will still be there, and will not decrease in the least.
To ease Kiana's suffering, K-423 can only sacrifice himself to bear some of this pain.
The reason why she didn't fully bear Kiana's stomachache? Well, she's not a saintess. Besides that, Kiana has to learn the consequences of her own actions herself.
"The other me... It hurts..."
"It's okay, I'm right here."
Entered into the stigma space, and immediately drilled her head into her other self's embrace. The pain in her stomach was being split in two, and Kiana's eyebrows, which were always tightly closed, finally relaxed a little.
"Now do you understand?"
"Hmm... I understand... next time I won't eat the Honkai beast meat..."
"No, you don't understand."
Feeling that her hair and back was gently stroked by her other self. Kiana who fell into a rare comfort, felt her heart feel very warm.
Her other self was like an older sister to him. Although often nosy, and annoyed him. Yet she was the figure she could rely on the most.
When she was bored, she would become a hot-mouthed demon who desperately asked to be spanked. But if she is in pain and feeling sad, then her other self will become an angel of mercy.
Just like this time.
"The other me... I'm glad you're always here..."
K-423 looked at Kiana silently: "Don't talk like someone who is going to die soon. Does it still hurt now?"
Kiana shook her head: "No, somehow it feels a little less."
K-423 who bore 80% of Kiana's pain, frowned with difficulty. If she could sweat, then she would definitely be breaking out in a lot of cold sweat by now.
"Next time, listen to my advice. Look, who's having a hard time, I'm always in trouble too."
"Hehehehe..."
Kiana chuckled in her arms.
Even though her stomach still hurt, her heart felt very warm.
"Thank you Sister."
When K-423 heard that Kiana called her by a different name. Her face suddenly froze.
"Sister? You call me big Sister!? Hahaha, you finally understand!! This pain, this pain isn't not bad!!" K-423 burst out laughing.
Kiana's face suddenly turned black.
Was it too late to go back in time and slap himself for calling this little devil big Sister?
What a cheap mouth!
"Hum!!"
Kiana buried her face into K-423's chest very dissatisfied.
