lol, they coulda literally translated the title imo.Suggest something if you can do better. Naming shit is... surprisingly hard.
IIRC: Shin=new, Megami=goddess, and Tensei=reincarnation/rebirth
So coulda been New Goddess Rebirth: Training the Demons -- Aka training female demons so you can 'birth' a new goddess.
Edit. Ps. Did a quick search, and Shin may been real/true instead, but had always thought it meant new for the game, what with it having roman numerals.
