You can write about any female character, you seem to be quite interest by Ochako so it would be better to put her as the female lead. But honestly I prefer the older women of BNHA, such as: Mirko, Lady Nagant, Ryukyu, Mount Lady, Midnight. I also like some female characters like Nejire, Momo, Mei, Mina, Toru that despite being invisible I like their cheerful personality, Itsuka Kendo, and some others, Tsuyu and Jiro are pretty cool too but the Fanarts make them better than they really are. But as I said before I prefer the older women of BNHA.
