is probably one of the most generous gacha's out there, don't get fooled by the expensive pity, the pity currency carries over and you can exchange it at any current rateup you wish for.
For example for every roll in a current banner you get 1 gold ticket, for every 200 gold tickets you can go to the shop and buy the rateup nikke for 200 gold tickets each copy.
The golden tickets never expire and you get one for rolling on any rate up (except friend points and permanent pool).
Also they give away rolls like they were candy and every 2-3 months they give away a free unit.
Also you get black tickets for rolling on the permanent pool but you can only use those to exchange permanent units or favorite items (to unlock bond scenes) they also cost 200 per copy or item.
