Tips for Nayuta. Also, a little flex hehe

Got Nayuta after 70 pulls and I got her yesterday on free full and somehow, she showed up again right now on free pull. So I thought it might be a sign to max her out. Is it gonna be a good decision? Crown is better than her and I have crown. Will it be useless investing on Nayuta? If not then can you recommend what stats I need to prioritize, skills and cube? Thanks!
