Place it at the climax of a transformation edit, after the build-up, then follow it with Giorno's Theme for the victory walk. For a versus edit, open with Mangekyo Sharingan as the rival power-up, then answer it with this clip at the turning point.
About this sound
This short clip captures Ichigo Kurosaki shouting Bankai, the command that unleashes his Zanpakuto's final form, in a fierce, rising voice that lasts about a second and a half. It feels sudden, intense and triumphant, like a hero stepping into full power at the exact moment a fight turns. The line comes from Bleach, where Bankai marks Ichigo's strongest transformation.
