@granny63020, your set looks fine for now. The only defense item I could suggest would be a Thyoras Tear. It blocks 100% of damage for 1 turn Once Per Battle. But it's super expensive right now like every other good piece of equipment with the impending battle plot. You could possible go with the one use version, the Thick Smoke Bombs which can be bought from player shops or from the Secret Ninja Training School. They do the same thing, but once they are used, they are gone for good. I think your set is fine for right now, so don't worry too much about it. When the battle plot comes out, I'm sure we'll be testing the opponents for their arsenals and abilities. I'm sure that neither of us will likely need to change your gear for most of it. Even for the final boss, we might be ok, if it's like the Wraith event where we got Sword of Malum and Blazing Embers from.
I'M hoping it will be a little more epic than that though, more on the level of the Obelisk War would be my preference.
