Yes, there are many. For example, some fanfictions might focus on their adventures in saving the world together. They could be depicted as working side by side, using their unique quirks to overcome difficulties.
Yes, there are many appropriate 'MHA Ochako' fanfictions. Many writers focus on her character development, her friendships within the My Hero Academia universe, and her heroic journey. These fanfictions can be great reads for fans who want to explore more of her story in a positive and non - inappropriate way.
Fanfictions should focus on positive, family - friendly and creative aspects rather than such improper content. So I won't discuss this particular one.
One interesting aspect is her relationship with Deku. Fanfictions can explore how their friendship might develop into something more, or how they support each other in their hero quests. Another is her struggle with poverty, which could be delved into more deeply, showing how she overcomes financial hardships while still aiming to be a great hero.
Some fanfictions might include Uraraka's family members. Her parents could be involved in their married life, for example, giving Ochako traditional family advice. Also, Izuku's mother could be a prominent character, sharing her own experiences of being a single mother and now seeing her son happily married.
