Abstract: 
In this talk, I will give a brief review on N-flation models. Moreover, I will present the recent work of N-flation with no-boundary condition which is one of several ways to avoid the singularities of our very early Universe. Even though no-boundary measure disfavours the histories of large e-foldings in inflation, we show another way to lift up the probability of inflationary histories without considering any other factors, but with the large number of fields such as N-flation fields.
