C & P

"Yuzu, are you alright?" Ichigo held Yuzu and called out softly.

"Brother? Cough cough..." Yuzu opened his eyes and answered, then continued coughing.

"Ichigo Kurosaki, move aside, I'll examine her." The unyielding, forceful voice of Ishida Ryuuken came from Ichigo.

"This is troublesome, Uncle Ryūken."

Ichigo quickly gave up his seat, while the others formed a large circle around Yuzu, ensuring fresh air was allowed in while watching over Yuzu with concern.

"A penetrating lung injury; treatment is needed," Ryūken accurately diagnosed Yuzu's condition.

"Ishida, shall I heal him?" Orihime asked. She had always played a support role in the team, but this time Ryūken refused Orihime's suggestion.

"No, your 'Santen Kesshun Rejection' feels more like a return to the body's previous state."

"Yuzu Kurosaki's last state was when she was pierced by the Chains Hell. We can't take that risk. Sawada, you're in charge this time!"

"The Activation of the Sun Attribute, combined with the healing of the Returning Dao, can promote the recovery of injuries!" Ryūken made a diagnostic plan.

"Okay, Uncle."

Tsuna raised his hands like a surgeon asking for tools, one hand igniting a yellow flame, the other emitting a gentle green light.

Having spent so much time in Soul Society, Tsuna has learned the art of teleportation, though he doesn't use it often. This is all thanks to Kenpachi, who is obsessed with battles, and the rewards he receives after each fight aren't based on what Tsuna wants, but rather on what the other person has.

Tsuna crossed his hands, placing the power of the Return Path below and the Sun Attribute Flame above, using the Activation power of the Sun Attribute to enhance the effect of the Return Path.

Soon, the pain on Yuzu's face disappeared, and he stopped coughing. After a while, he was able to open his eyes and show a smile.

"Alright, the injuries have all healed. A good night's sleep will do the trick." Tsuna withdrew his power.

"Thank you, Gang-ge, I'm feeling absolutely better now."

Yuzu's playful and adorable appearance made Tsuna unable to resist ruffling her head twice. He then quickly made way for the girl's tearful parents to hug her.

"Well done, Tsuna! I knew you'd have a way." Ichigo put his arm around Tsuna's shoulder, trying hard not to let the little pearl fall. If there weren't no other spots available, he would have liked to be one of them embracing.

"You're the one who saved him. If nothing unexpected happens, your anxious state will also be partly your fault if Yuzu gets into trouble." Tsuna mercilessly stabbed Ichigo in the back.

"Haha, I'll go check on Karin." Ichigo scratched the back of his head, chuckled, and dashed off.

Tsuna and Tatsuki exchanged a glance and walked towards Karin in tacit agreement, as they were also very interested in Karin's condition.

Unlike the fleeting power of the Yuzu, Karin is still floating in the air. Tsuna and Ichigo, who both possess Quincy heritage, can sense that Reishi are gradually gathering around Karin.

"It looks somewhat similar to my Earth Flame," Tsuna commented.

The Earth's defining characteristic is gravity. When a planet collapses, it forms a black hole with a strong gravitational pull, continuously attracting everything around it.

Unlike the earth element, black holes absorb things without leaving any trace, while the Reishi gathered on Karin's body are all concentrated at one point, as if they were forcibly squeezed together.

After these Reishi gathered into a sphere the size of a fingertip at Karin's chest, the Reishi entered Karin's body, and she slowly floated down from the sky.

"Huh? Ichigo -nii, Tsuna-nii, Tatsuki- chan, why are you all looking at me like that?" Karin stretched her body, feeling more relaxed than ever before.

"Oh right, Ichigo- nii, why aren't you going to rescue Yuzu?" Karin said anxiously.

"Don't worry, Yuzu has woken up."

Before Ichigo could finish speaking, Karin rushed past him, hurrying towards Yuzu's direction.

Tsuna watched Karin's retreating figure thoughtfully. "Ichigo, don't you think the way Karin runs has a bit of Hirenkyaku style?"

"No way? Mom probably didn't teach her that, right?" Although Ichigo and his parents didn't explicitly cover up the supernatural events from Karin, they also didn't teach her how to cultivate.

"Why are you making wild guesses? Why don't you just ask Karin later?" Tatsuki slapped each of them. Just like when they were kids, when the three of them were together, she was the leader.

Another round of chaos and howling ensued. Tsuna still couldn't quite accept the Kurosaki Residence's way of expressing emotions, and even the usually calm Karin was starting to emulate Isshin's emotional expression in this matter.

Finally, after an unknown amount of time, the Kurosaki Residence calmed down, and the Ishida Residence's picnic and barbecue party was ready.

"Yuzu, Karin, do you know the names of your abilities?"

Seeing that the Kurosaki Residence had calmed down a bit, Tsuna, who was eating a piece of grilled meat, quickly changed the subject. He didn't want to be disturbed by Isshin's crying while he was eating.

"Oh, right? Tell Mom what your Saint Letters is!" Masa's attention was immediately diverted.

"Saint Letters? What's that?" Yuzu blinked his eyes adorably.

"It's about a power within you, what's the name of that thing...?"

"Stop teaching people, come and stay over there." Tsuna stuffed a piece of grilled meat into Ichigo's mouth to stop his mumbled explanation and pulled him to the side of the table.

"Close your eyes and feel. You can find many tiny particles in the air; those are Reishi. Then calm your mind. There are similar substances in your bodies. Use your mind to explore them, and they will give you feedback, perhaps a word, perhaps a letter..."

No one found Ryūken's introduction irritating; following his method, Yuzu and Xiali quickly got into the swing of things.

"As expected, A Long is much more professional." Masa sat down at the table and chatted with Hae. "It reminds me of the time we studied together when we were kids..."

"By the way, why doesn't Mom teach Yuzu and the others herself?" Ichigo sidled up to Tsuna to start a discussion.

"Aunt Masa's carefree personality probably made her a bit of a ditz when she was little. As for theoretical knowledge, I don't even need to look to know that Uncle Ryūken is more reliable."

As Tsuna guessed, he glanced at Ichigo. If Masa wasn't stupid, then there was Ichigo Kurosaki. He and Ryūken would be able to launch long-range attacks together, and White would never be able to get close to Masa.

As everyone ate and chatted, the two little ones quickly found their Saint Letters following Ryūken's instructions.

"Mom, I know! It's that Saint Letters!" Yuzu said excitedly, raising his hand.

"As expected of your Mom's daughter, you're amazing!" Masa didn't hold back her encouragement.

"Masa, Yuzu and Shirley are very talented as Quincy, even more so than Ichigo."

"I understand, A Long, I'm leaving them in your care!" Masa was very understanding and showed no intention of forcibly interfering.

"No, Uncle Ryūken, you can give your evaluation, but why do you have to include me? Besides, my Saint Letters is an A, what's wrong with my talent?" Ichigo protested vehemently.

"It's all because you always use the Spirit Bow and Arrows as a knife..." Even Ryūken started to complain.

"That's not my fault, they just look too much like the Tensa Zangetsu..."

"Stop babbling, you two! Come on, my darling daughter, tell Daddy what your amazing powers are!" Isshin looked like a lovesick old man.

Karin glanced at Isshin with disdain, "My Saint Letters is C, press, which can compress the surrounding Reishi into a sphere and then launch it out."

As Karin spoke, she began to demonstrate. She held up a finger, and all the surrounding Reishi gathered towards her fingertip. Just like Tsuna had seen before, a ball of Reishi the size of a fingertip floated at her fingertip.

Karin pinched the Reishi ball and launched it like a marble. With a bang, the launched Reishi Reishi exploded like a hand grenade.

"Its power is quite considerable. Are there any limitations on its use?" Ryūken was recording data, preparing for Karin's future training.

"No, as long as there are enough Reishi around, I can release as much as I want."

"It hasn't escaped the control of the Reishi; it looks more like the Spirit Bow and Arrows has been transformed into an attack resembling a cannonball." Ryūken paused as he wrote, "Do you accept that your Spirit Bow is initially presented in the form of a slingshot?"

"Well... Uncle, you can make the decision." Karin had only just begun to come into contact with these powers and didn't have much of a judgment on her own.

"That's settled then. If you can condense the projectiles fast enough, the Spirit Bow can be replaced with a firearm. We'll test the specifics later." In just a few words, Ryūken brought in the firearms.

"Ryūken's thinking is really leaping around. Is he no longer satisfied with just bows?" Tsuna asked Uryū.

"Isn't it you? You told Father that Quincy used firearms to fight in the Wandenreich a thousand years ago. Grandpa didn't bring this information with him, and our own fighting style is fixed. Father probably wanted to try it on Karin, right?" Uryū said.

"Next up is me, the Saint Letters for Yuzu is P!" Yuzu playfully made a V next to his eyes, "Purift, purification."

As soon as he finished speaking, Yuzu became flustered. "But Yuzu doesn't know how to express it."

Upon hearing the word "purification," everyone immediately understood why the Chains of Hell had disappeared; it was undoubtedly due to the Saint Letters at work.

Masa quickly comforted her, "Yuzu, don't be sad. You've already shown us your abilities."

"Really, Mom?"

Yuzu was overjoyed to receive a positive answer from Masa. Everyone attended the family banquet prepared by the Ishida Residence, while Ryūken was silently planning his next training session.

"As for Karin, I plan to help her manufacture the Spirit Bow first, so that she can initially form an effective combat force and have the ability to protect herself. As for Yuzu, I prefer a balanced development, starting with learning the basics of Quincy."

Ryūken's plan was unanimously approved by everyone, except for Karin, who silently raised her hand.

"Um, I've been carefully sensing it, and it seems my ability hasn't been fully revealed yet, but I'm not sure what it is. It doesn't seem to be the power of Saint Letters..."

(PS: The Saint Letters of the Yuzu needs no further explanation; we always need to find a reason to break the Chains of Hell, so we decided on purification.)

As for Karin, I designed it entirely according to her interests and hobbies, compressing Reishi particles into a sphere.

The author of this chapter includes a picture of the two sisters as they grew up; they, Quincy, should embody the spirit of Yuzu.
