[OP06-101_p2] - O-Nami (500 Years in the Future: SP)

I activated this [Activate: Main] effect after this Character gained [Banish] according to the [On Play] effect of "OP06-101 O-Nami". What happens if I then attack with this Character and deal damage to my opponent's Leader?

No Trigger is activated according to this damage and your opponent trashes a Life card.
