Chance is low, but it's possible

U only know if u try

Take my advice don't do it I spend 5 pack on 79.00 and didn't get them they keep giving me the wrong 5 star servant 3 times 2 of two were 5 star caster that weren't on rate up don't do it wait for next month to get Scheherazade save yourself from the pain trust me

I rolled only 30SQ in hopes of getting NP3 Saber and got Murasaki instead. So it is possible, very unlikely, but possible.
