FFVII Rebirth ITA - Chp.10 Hard Mode - Gi Nattak bossfight

I'ld like to be done with the Hard Difficulty playthrough before trying the last two challenges of the sim, since now i have the Gotterdammerung it should be even quicker. Alas, in December i have very little time for gaming, so wouldn't try the Bonds of Friendship and To be a hero anyway.
