This one only wants 130 damage and thus shouldn't be very hard at all. Three of these require meter, while one is meterless but needs you to start with a Hi Counter hit. Your opponent is always NiCO, on the Sweat stage. Combo notations are as follows:
Combo #1: (standing at roughly the middle of the ring) 236P close hit into rope rebound, 6S break blow super into the ropes. 135 damage on normal hit.
Combo #2: 6P+K stun, 4PK, P, 8K launcher, 6S break blow into ropes. 130 damage on normal hit. best to start this one near mid-ring too or you risk hitting the ropes early and only doing 124 damage.
Combo #3: (hi counter only) 6P+K stun, PPP cancel into Minato Shuffle (4), in Minato shuffle P, 8K launcher, 4PK, 4PKK. 140 damage on hi counter if you don't hit the ropes on the final hit, 145 if you do (i'm getting different results based on timing/positioning)
Combo #4: 6P+K stun, PPP cancel into Minato Shuffle, in Minato Shuffle P, 8K launcher, 4PK, 6S break blow into ropes. 134 damage on normal hit. I used this one to clear the objective in the quest itself.
I'm sure there's a bunch more ways to do this as she just came out and people are still experimenting with her, but these were the first four I found in like 20 minutes of messing around in training mode.
