Sephiroth1999AD is right, you are at a good level plus if you get (SPOILER)the Masamune it will be a walk trough the park. One tip, before you fight the last boss, you should try to get every enemy on your list. Then you have 100% for the game. You can use the collection guide for that. (When you have (SPOILER)Masamune it's going to be way easier)
