Bankai is the final released form of a Soul Reaper's Zanpakuto in Bleach, the manga and anime series created by Tite Kubo. Byakuya Kuchiki, captain of the 6th Division, is one of the most iconic users, and his battles are scored with pieces like Reminiscence from the Bleach original soundtrack. Clips of the activation music spread through anime forums, AMVs and later short video edits, where the rising score became shorthand for any dramatic power-up moment far beyond the series itself.
