Distracted by the fireworks no one saw Hotarubi taking off her kimono, now only wearing her thief clothes.
She quickly ran towards the wagon from behind and pulled her tanto from  her sash. One of the guards saw the thief and ran towards her ready to empale her with his spear, however the female was faster, running in zig-zag  and confusing the guard she quickly slammed him against the floor using a martial art movement.
Because of the noise the fireworks caused the other guards did not hear their partner being knocked out.
