Wew, Nutaku's low odds on SSRs are being known by the people, what a shock!.
Seriously, we all know Nutaku's odds are WAY lower than DMM's, and, they also REFUSE to raise the odds 'cuz "Original Game". There's also been a thread not long ago about this, so yeah, don't hold your breath on something changing soon, I have spent 50k jewels since May and I haven't got jackshit, that's how it is.
The sooner you realise this and quit this shitty gacha game, the better.
Completely fake btw, you can spend 100k jewels or Gold Coins and get jackshit, and you can't make me think otherwise.
