because it wasn't good for them. almost none spent in it.

This was way before my time but i'm very interested, what was in this treasure?

It wasn't a treasure, Mabui would appear in Konoha and sell ninjas for coupons. You could only buy 80 frags of a ninja instead of just 1 or 2.

Some common stuff you'd probably see was Sailor Sakura, a Pain here and there. And probably some various power items.

The mabui npc stopped showing up in March-April and it was the go to place to get gnw tenten at the time since edo treasure wasn't available at the time. Konan was a favourite ninja to be there and animal pain. No hashirama, tendo, no kage rares, etc.

Yea, would be nice if it would come back, I mean, why not..

I spent all of my coupons in the sage event :(

This should come back tho and also have them from the other ninja lands

She should just be there 24/7, I don't know why she wouldn't be. It's not like the Ninja she sells are heavily discounted or anything, but it is useful.
