I Don't wanna go through all the things i typed out, But I'll paraphrase.

get friends.

If you can get even 4 friends to help you, You can do the KSNM99 5 Times (you +4 of them).

KSNM99's drop BB Items, So while you build pops for the "NQ", you have a shot at your BB item.
**Also note, the SE update say "At least 1 will always drop" implying 100% chance of "upgrade", but also chance of more than 1 pop item per KSNM/Faf/beh/etc

So now you can pop Faf/etc 5 times back to back, and according to the notes, get 5 pops for King guy. then pop King guy 5 times back to back.

Do you see what I'm getting at >.>? basically with just you and 4 friends, you get 10 chances at a Black Belt item in 1 sitting. Its a lot better than it sounds, It just requires friends to help. Most people i know have been sitting on hundreds of kindred seals (because frankly most KSNM's suck for gil these days)... But if yours don't i can understand how upsetting it must be :|
