Fanfiction.net is also a good place to search. There are many different categories and fandoms represented on this site. However, the quality can vary, so you may need to do some sifting through the results to find the really good eri and harima baby fanfiction. Look for stories with high ratings and positive reviews.
One great eri and harima baby fanfiction could be about their journey into parenthood, facing the joys and challenges together. For example, a story might focus on how they adapt their lives to take care of the baby, like changing diapers at odd hours and sleepless nights but still being filled with love for their little one.
Obviously, Harima and Eri are the central figures. Harima might be a bit of an underdog, trying to find his place in the world. Eri could be a popular girl who has a hidden side that only Harima gets to see as their relationship develops in the fanfic.
One popular theme could be friendship development. Maybe Harima and Eri start as acquaintances and gradually become really good friends, sharing secrets and having adventures together. Another theme might be about achieving common goals. For example, they could be working towards a school project or a community event. Also, themes of self - discovery can be present. As they interact, they might learn more about themselves and their own capabilities.
A great Deku and Eri fanfiction could be set in a future where Eri has grown up a bit. She and Deku go on a mission together to rescue some hostages. Deku is proud of how far Eri has come and they work together as a great team.
A simple idea could be that Haru and Eri participate in a Digimon tournament together. They train their Digimon side by side, and in the process, they start to understand each other's training methods better. Their Digimon also form a closer bond as they spar with other Digimon in the tournament.
A fanfiction might focus on Haru and Eri getting lost in a strange part of the digital realm. They have to find their way back home while also helping some baby Digimon along the way. During this journey, they learn more about each other's dreams and fears. Haru realizes Eri's determination is much stronger than he thought, and Eri sees Haru's kind heart in a new light.
Some Tumblr blogs are dedicated to sharing and recommending fanfiction. You could search for My Hero Academia fanfic blogs and then look specifically for Deku and Eri stories. They might also have reviews or summaries to help you decide which ones to read.
Healing is another major theme. Fanfics often explore how Eri heals from her traumas with the help of the kind - hearted characters in My Hero Academia. This can involve her mental and emotional healing as well as learning to live a normal life.
For Naruto, you can explore his post - Hokage days in relation to Eri. Maybe he's more cautious and wise, and he imparts his knowledge to Eri. You can show his growth in handling diplomatic situations if Eri is from another village. For Eri Kitamura, if she's a new character, you can start by giving her a distinct personality. For example, if she's shy, Naruto can help her come out of her shell. Or if she's headstrong, Naruto can teach her the value of patience.
