Kie began to overthink. She picked up the card but didn't plan to use it immediately, deciding to wait until evening.
Because the card's description said it would expel toxins and other impurities from the body.
This wasn't just about restoring ten years of youth; it would also improve overall health!
"Huh? Oh, there's more?"
She hadn't expected another card underneath!
The second card was a B-Class Upgrade Card, which could upgrade abilities, items, or weapons below C-Class.
Her first thought was her water manipulation ability, and her body enhancement ability.
Both were C-Class, so they could be upgraded to B-Class.
"Really... I don't know how to thank you enough."
To be safe, Kie picked up this card and found another identical B-Class Upgrade Card underneath.
This was clearly intended to help her become stronger, to survive and even fight Demons in this world...
Even if she wasn't skilled in combat, relying on these abilities and physical enhancements would probably be enough to defeat Demons, right?
Thinking that her son Tanjiro would soon join the Demon Slayer Corps to hunt Demons lurking at night, Kie easily deduced that Kaito was also doing this to protect her.
The shields were just temporary protection, but having the strength to defeat Demons would directly solve the problem.
Taking the second B-Class card, Kie saw there was another underneath and sighed helplessly.
'Really, he was giving too much.'
For her to pull these herself, aside from the question of whether she could even get them, the points required would be thousands or tens of thousands...
She definitely couldn't pull them without several ten-pulls.
The fourth card...
An A-Class Upgrade Card!
The fifth card...
Another A-Class Upgrade Card!
The final card...
An A-Class Martial Arts Copy Card...
It contained a copy of all of Kaito's martial arts skills, though after copying, it would only be at the A-Class level.
But even so, this would instantly elevate Kie to a grandmaster level of martial arts proficiency.
A-Class was the absolute limit for ordinary humans.
Probably the level of top-tier experts in a standard martial arts world.
It was also the level of strength Yoriichi had demonstrated.
Kie held these six cards in her hands, momentarily at a loss for words.
She could only acknowledge that these were indeed gifts Kaito had carefully chosen for her...
Considering her world was unsafe with Demons lurking, her abilities were weak, and she couldn't fight, giving her these cards was the most suitable choice.
This was more useful than acquiring external things like weapons.
True strength came from within.
Especially for future parent-child activities, she would be able to contribute significantly.
She let out a long sigh.
Internally, she was undoubtedly overjoyed, even feeling butterflies in her stomach, wanting to jump for joy.
But what troubled her was that Kaito had given her too many wonderful things.
When Kie had invited Kaito, she hadn't expected him to give any particularly nice gifts. She had thought things like fruit or skincare products would be acceptable and understandable.
Misuzu and Sayuri had given those kinds of things.
But Kaito...
He had not only given her children many gifts but had also given her more, and better ones!
The intention behind these gifts was clear to Kie.
Though she was simple and kind, perhaps appearing a bit naive compared to modern women like Sayuri, not understanding many things, she was not a foolish woman...
"Sigh..."
She didn't know how to face Kaito now.
But he was in her tea room, planning to stay for a few days. She would have to face him eventually.
After putting the cards away, Kie walked to the mirror, fixed herself up, and left the room with a smile.
"Sorry for the absence. Let me refresh your tea."
Entering the tea room, Kie deliberately sat in the vacant seat to Kaito's right, picked up the teapot, and began brewing.
Just as she did, Kaito and the ladies had nearly finished the tea in the pot while chatting.
"Well, we can talk more about that when Demons appear at night."
Kaito nodded with a smile, continuing their previous conversation.
Kie asked curiously, and Kaito explained.
They wanted to see Demons, to get a taste of bloodshed and broaden their horizons, to gain experience.
Misuzu, having gained abilities but never fought before, wanted to test them. She also seemed intent on adapting to certain scenarios in advance.
Considering that future parent-child activities might involve combat, adapting now would be beneficial.
"Oh, Mrs. Kamado, please come tonight too. Also, bring Tanjiro and Nezuko."
"Is that alright?"
"Of course. With me around, there won't be any problems. Especially for Tanjiro, since he'll be slaying Demons in the future, letting him see a Demon early won't be an issue."
Nezuko would need about twelve hours to become the Demon King. Bringing her along tonight would be feasible.
As for whether there were Demons here, Kaito wasn't sure. There probably would be at night. If not, they could check other towns.
He just needed to detect a scent different from humans, tinged with blood, to locate one.
With Kaito's current sensory abilities, it wouldn't be an exaggeration to say he could perceive everything within a million-meter radius!
For instance, in the neighboring town, he could easily sense a couple engaged in a fierce "battle" in the morning.
Sensory perception included detecting presences, forming mental images, essentially like radar.
With his current SSS-Class strength, achieving this was trivial, especially given his mastery of various Authorities and magic.
"Well then... after the inn closes tonight, I'll come with you. Kaito is right; we'll have to face this eventually."
While everyone could choose not to participate in parent-child activities, and even if they did, they wouldn't truly die, participating earned points!
Could they afford to give up points?
Points offered infinite possibilities, like a chain with a hook, always dangling in front of them.
If they were all as invincible as Kaito, they could be indifferent.
But most of them were ordinary people.
Who wouldn't want to become powerful? Who wouldn't want to become younger, more beautiful, and even live for a very, very long time!
