Arc 1From Shihoin Twins to Shunkō
Ye Yang grew from a gifted Shihoin child into a Third Seat and helped Yoruichi and Kisuke Urahara rise through the Soul Reapers. After years of training and dangerous missions, Yoruichi defeated Mongoose in the Tenshintai and developed the technique Ye Yang named Shunkō.
- Ye Yang cultivated Taiji before birth, grew up alongside Yoruichi, and began training in Soul Reaper skills while guarding his family from a hidden threat in their lessons.
- Ye Yang and Yoruichi celebrated their coming-of-age ceremony with music and dance, passed the Shin'ō Academy entrance exam, and joined Kisuke Urahara in Class One.
- Ye Yang, Yoruichi, and Kisuke became the academy’s top students, built a secret base, and led a practical exercise in the World of the Living where they faced real Hollows and Grimmjow Jaegerjaquez.
- Ye Yang revealed Silver Rend and drove Grimmjow away, after which he, Yoruichi, and Kisuke graduated early and joined the Punishment Force.
- Ye Yang and Kisuke defeated escaped Soul Reapers, then earned seats in the Second Division, while Yoruichi became lieutenant after defeating Ye Yang in a staged challenge.
- Ye Yang took charge of the Maggot's Nest and subdued its prisoners without killing them, while Yoruichi handled lieutenant duties and Kisuke developed new devices.
- Ten years later, Ye Yang and Yoruichi taught Byakuya, and Kisuke introduced the Tenshintai, which let Yoruichi summon Mongoose and attempt to achieve Bankai.
- Yoruichi fought Mongoose repeatedly, improved with Ye Yang’s techniques, and finally combined Kidō with Hakuda to defeat her, prompting Ye Yang to name her new move Shunkō.
