Shinseki No Ko To Wo Tomaridakara De Nada Ka High Quality -

"Shinseki no ko" – 親戚の子 would be "relative's child". "To wo tomaridakara" – とめる is to stop. "Dakara de nada ka high quality" – "so it's nothing but high quality?" Maybe the user is asking about the quality of something related to a stopped relative's child? Or perhaps they're questioning if the only thing left is high quality because the child/relative stopped doing something.
