If I am you I'll switch out iwatooshi with another sword, maybe an oodachi if you have another high leveled one or a tachi (it is better if the tachi is R4 since they can hold out longer, maybe ichi-nii or kousetsu? since their stats are pretty good).

Iwa is pretty useless for me in KBC fight. Good luck :>
