Amamiya Miyako looked at the silent Ishida Ryuken, no longer speaking, waiting for Ishida Ryuken.
"None of this concerns you, does it?" After a long time, Ishida Ryuken spoke again. "Now that you've become a Shinigami, Quincy matters are no longer your concern."
"Unrelated, huh…" Amamiya Miyako looked at her hand, gathering reishi again. "Then, Ishida Ryuken-san, please tell me, what exactly is in my hand? Why were all the deceased that day of unknown cause of death? Why was my body autopsied by you? Why did I survive as a soul, and did the souls of others dissipate, or were they devoured by Hollows, or were they sent to Soul Society?"
Ishida Ryuken certainly couldn't tell him that the others didn't even leave their souls, and only Amamiya Miyako survived that accident, 'alive'.
"Ishida-san, don't avoid it anymore. As a Shinigami who can use Quincy powers, I am also an anomaly in the eyes of Shinigami. That inexplicable death is still fresh in my memory, and I… I don't want to experience such an inexplicable death again," Amamiya Miyako persuaded.
"That incident was definitely not an accident. Have you completely investigated what's hidden behind it?"
"…" Ishida Ryuken didn't know whether to tell Amamiya Miyako the information he had investigated, but Amamiya Miyako's words were indeed correct: a Shinigami who used Quincy abilities was an anomaly in the eyes of true Shinigami.
Amamiya Miyako saw the hesitation in Ishida Ryuken's heart and decided to raise the stakes.
"I am currently a Shinigami of the Gotei 13, affiliated with the Thirteenth Division. The main tasks of the Thirteenth Division are to go to the Human World to purify Hollows and perform soul burials for wandering souls," Amamiya Miyako explained.
"Ishida-san, Soul Society, as one of the Three Realms, surely preserves a large amount of information. I can help you search for information related to Quincy there, and I will also keep an eye out for anything related to Quincy that appears in Soul Society in the future."
Ishida Ryuken was silent for a while before he spoke.
"What is your purpose? Why do you want to do this? The truth isn't important to you; as long as you do your job steadily, none of this matters." Ishida Ryuken was very confused, not knowing why Amamiya Miyako proactively suggested these things. "And the Quincy power, as long as you don't use it, nothing will happen."
"Ishida-san, you shouldn't be that naive. 'An innocent man is guilty because of his wealth.' You should know that saying. As an unusual Shinigami, as long as I possess Quincy power, trouble will actively seek me out," Amamiya Miyako said with a bitter smile.
"I only have one true purpose," Amamiya Miyako stated. "That is to master power, so that no one can ever harm me again because of my uniqueness. Therefore, I boldly ask you, Ishida-san, please teach me how to use Quincy power."
Ishida Ryuken felt somewhat surreal at this moment, not expecting to be asked for guidance by a Shinigami. This was truly…
But at the same time, Ishida Ryuken also understood the motive behind all of Amamiya Miyako's actions. After a long wait, Ishida Ryuken had an answer in his heart.
He revealed a faint smile, "You, a Shinigami, are asking me, a Quincy whose strength is unfathomable, for guidance. What if I can't help you?" Ishida Ryuken said this, but in his heart, he had already agreed to the matter.
The reason for his wife's mysterious death had not yet been truly confirmed, even though he already had certain suspicions. Although investigations in the Human World could be carried out by himself, Soul Society was indeed his blind spot. If someone could truly help with the investigation, it would indeed be beneficial to him. Besides that, Ishida Ryuken had other matters that only Shinigami could handle.
"That's still better than me, a half-baked Quincy," Amamiya Miyako said with a smile, knowing that Ishida Ryuken had more or less agreed.
Ishida Ryuken did not possess such a thing as the glory of a Pure Blood Quincy. For him, Quincy abilities were merely tools. Therefore, he felt nothing about teaching Amamiya Miyako, an anomaly. Moreover, Ishida Ryuken also detested Quincy power; if the truth had not yet been fully investigated, and he could not lose this power, Ishida Ryuken would not have continued to train this power in private.
Therefore, Ishida Ryuken did not teach his son about Quincy knowledge. Even though Ishida Uryū had been taught by his grandfather Sōken Ishida since childhood and was very interested in Quincy power, Ishida Ryuken did not want to impart any knowledge to Ishida Uryū.
He hoped that Ishida Uryū would become a doctor who saved lives, like himself, rather than a Quincy who only took lives. The matter of the Quincy, he would bring to an end himself.
"Oh, right." Ishida Ryūken returned to his desk and pulled out a black box from a drawer. "Here, this is for you. It should be something your family once owned."
Ishida Ryūken tossed it to Amamiya Miyako, who looked at the familiar black box. Opening it, a silver cross lay quietly inside. Amamiya Miyako gripped it tightly; sure enough, the shape of this cross was identical to the Quincy Cross her Zanpakuto used.
"Follow me." Ishida Ryūken walked out of the office. Ishida Ryūken led Amamiya Miyako to the hospital's basement, then opened a door in an inconspicuous corner.
Ishida Ryūken and Amamiya Miyako stepped inside. After entering, they arrived in a pure white space, surrounded by countless white high walls arranged without any order.
"This is a reishi space I constructed. Here, no one will disturb us, and no one will discover us," Ishida Ryūken said.
Amamiya Miyako surveyed her surroundings, realizing this was the very place in the original story where Ishida Ryūken helped Ishida Uryū restore his Quincy powers.
As expected of a Pure Blood Quincy, his ability to construct space using reishi is truly impressive. Amamiya Miyako secretly marveled.
"Let me be clear, I'm only responsible for teaching. How much you learn depends on you," Ishida Ryūken said. "Also, don't forget what you promised."
"Yes, I understand, Ishida-san." Amamiya Miyako gripped the Quincy Cross she had just received.
"Then let's start directly." Ishida Ryūken reached into the inner pocket of his chest and pulled out his own Quincy Cross. Ishida Ryūken's Quincy Cross was not the same as Amamiya Miyako's; his was a five-pointed star, while Amamiya Miyako's was a cross shape.
The five-pointed star is the true symbol of a Quincy. Amamiya Miyako didn't know what the cross-shaped Quincy Cross represented; perhaps it was a symbol of the mixed-blood Quincy lineage that left Yhwach a Thousand Years Ago, or perhaps it was a mark of the mixed-blood Quincy in the Human World.
"The Quincy's ability is to manipulate reishi. Whether in combat or movement, all techniques are inseparable from reishi manipulation," Ishida Ryūken said, as the Quincy Cross in his hand began to glow with a bluish-white light, gradually forming a small bow.
"Use the cross in your hand to form a reishi bow."
"Since you can already use Lingzi Jisou, it means your reishi manipulation has initially entered the realm. Now, try to control the size of the condensed reishi bow."
"The larger the reishi bow, the greater the power of the arrows it can shoot, but the speed of reishi convergence will gradually slow down. Conversely, the smaller the reishi bow, the less powerful the arrows, but relatively, the speed will increase. Of course, if you are skilled enough, none of these will become limitations for a Quincy."
"Next, let's use combat to meticulously experience the Quincy's ability to manipulate reishi." Ishida Ryūken raised the small bow in his hand with one hand, without any drawing motion or any intention of using Lingzi Jisou.
Then, arrows suddenly formed near his bow, and not just one. The arrows whistled out, moving incredibly fast.
Amamiya Miyako instinctively wanted to draw her sword to counter, but Ishida Ryūken's reprimand immediately came.
"Don't draw your sword. If you truly want to learn the Quincy's power, then do not use a Shinigami's Zanpakuto. Use your hand to gather reishi, and use arrows called Holy Arrow of Destruction to block me."
