Background / History

Sun Keiyun initially lived under the name Kamiya Keiyun in the Naruto world. He cultivated the Bright Virtue Method, pursued mastery beyond hand seals, and developed techniques through independent experimentation. 33

After killing Suikazan Fuguki, he rejected the identity and moral framework of a ninja. Reclaiming the name Sun Keiyun became a spiritual turning point: he called himself a Cultivator and challenged others to consider why they cultivated at all. 143

He apprenticed himself to the physician Shinnō, seeking medical knowledge so that he could save and treat people himself. Shinnō entrusted him with a 4,600-herb compendium, meridian and acupoint charts, and foundational medical texts. 148 149 During this period, Keiyun sheltered and relocated large groups of orphans and displaced people. 149

In the One Piece world, Sun Keiyun awakened in Marine G-9 Fortress's prison. Malnourished but calm, he built a System for his clone using Ancient Starry Sky Tree leaves and the Power of Creation, trained practical skills, and took Marine soldier Ron as a disciple. 370 371 He escaped, deliberately entered Captain Shilai's orbit, and accepted a Marine advisor position to gain access to Marine Headquarters and build influence before the Summit War. 377 378

He later joined the Marines as a new recruit, rapidly established a reputation through sparring, and gained the confidence of Sengoku, Tsuru, and the Admirals through his military and organizational proposals. 416 418 422 423 After Imu's death, he took control of the World Government and directed its future alongside the Marines. 487

In the Primordial Era, he became an Emissary of the Star Luo Palace and founded Senluo Company. He expanded education, agriculture, industry, research, legal institutions, cultivation methods, and military technology across the Star Luo Domain. 502 503 504 His later rise culminated in his fusion with the Heart of Time and creation of the Eternal True Realm. 549 550

Personality

Sun Keiyun is pragmatic, analytical, and highly adaptive. He consistently studies the rules of each world he enters, then selects the path most likely to produce long-term influence rather than immediate survival alone. He deliberately used imprisonment, Marine service, false identities, and political alliances as tools toward larger goals. 370 378 399 414

He presents cultivation as a moral undertaking, arguing that strength should not be used to oppress the good or aid evil. He values talent, but judges it by character as well as ability; he considered Mei Terumi worth recruiting because she was kind-hearted, while deeming anti-social power holders sources of sin rather than talents. 143 144

His compassion is selective but genuine. He learned medicine to help others, relocated orphans, protected Yuliu from the Demon Seed's influence, and investigated why civilians became pirates rather than treating every pirate as irredeemable. 148 149 348 386 Conversely, he is willing to manipulate others—including using the Great Soul Shifting Technique to make Lina loyal—and treats cloned people as instruments for his larger civilization-building plans. 403 547
