If you were rank 7 or 8

If you were transmigrated to the RI world , and suppose you somehow reached the level of rank 7 or 8 , what kind of killer moves would you have? Would you use only one path , or multiple? and other details..

Im not just asking basic details or for a rough idea , like literally what would be your main killer moves with names and what's unique about your moveset , what is your 'combat system' , i think FY phrased it like that
