In this fanfic, the relationship between Shimura Tenko and Uraraka Ochako could be full of interesting dynamics. Maybe it's a friendship that develops through shared challenges in the BNHA universe. They might support each other in battles or during their hero training.
Perhaps Shimura Tenko has some information that Uraraka Ochako needs for her own goals, like understanding a certain villain's motives. So, Uraraka Ochako tries to get close to Shimura Tenko to get that information, and in the process, a relationship forms. It could be a relationship filled with mistrust at first but then turns into something more positive as they get to know each other better.
If Ochako becomes a villain, her relationship with Deku would be severely strained. Deku, being a hero - in - training, would be conflicted between his feelings for her and his duty to stop villains. He might try to reason with her at first, but if she continues on her villainous path, they could end up enemies.
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.
In ancient words, names could only be answered by providing a specific plot or character setting. You can tell me the general content of the story or provide some keywords so that I can better search for the name you want.
In some fanfictions, new original characters are introduced. These new characters are designed to be a potential threat to Uraraka's relationship with Deku. They might be transfer students with amazing quirks who immediately take an interest in Deku. Uraraka then sees this new character getting close to Deku and becomes jealous, leading to various conflicts and emotional drama in the fanfiction.
As of the latest chapters, Izuku and Uraraka have shown some mutual interest and closeness, but it's not a definite romantic pairing yet. It's still evolving in the story.
