Ch. 1Moonlight
After awakening as the sickly seven-year-old Gekkō Byakuya in Konoha, Byakuya received a Soul Reaper system gift and attended a dream lesson taught by Sōsuke Aizen. He woke with a Zanpakuto and began Jinzen, determined to survive his Bloodline Disease and the coming war.
- Byakuya realized he had transmigrated into the Naruto world as a Gekko clan heir whose Bloodline Disease had nearly killed him.
- The system awarded Byakuya a Zanpakuto and night-session access to Shin'ō Academy, and he converted his family sword into an Asauchi.
- Byakuya entered a dream classroom, where Aizen taught him about Reiatsu, Zanpakuto, and Jinzen.
- Aizen confronted Byakuya about recognizing him, but the system intervened when Aizen tried to restrain him and altered Aizen's memories.
- Byakuya woke beside his younger brother Hayate and began practicing Jinzen with the sword across his lap.
