The plot has to be engaging. It could be something like they are thrown into a strange situation together, like a new villain threat that only they can face together. Also, the way their relationship is portrayed is crucial. It should be believable, whether it's a friendship or something more romantic. It should gradually build up, not be too rushed. In many good fics, the author also adds some unique twists to the My Hero Academia universe to make the story stand out.
One popular 'toga x izuku fanfic' is 'Green and Crimson'. It has an interesting take on their relationship, exploring how Toga's chaotic nature interacts with Izuku's heroic ideals. Another one is 'The Unlikely Bond' which delves into how they might form an alliance in an alternate universe scenario.
In this type of fanfiction, the plot might start with Izuku being bullied as usual because of his quirkless state. Toga witnesses this and for some reason, feels a connection. Maybe she was bullied in the past too, for her abnormal quirk. Toga then decides to protect Izuku from the bullies. Izuku is shocked but also grateful. As time passes, they start to communicate more. Izuku shares his dreams of being a hero even without a quirk, and Toga starts to question her own villainous ways. Their relationship develops as they influence each other's views on life and society.
The plot could involve a post - war scenario. After all the chaos, Toga and Izuku find solace in each other. Toga might have had a change of heart during the battles and Izuku, being the empathetic person he is, sees the good in her. They get married secretly at first, and then gradually try to make their relationship known. Their union could be a symbol of hope for a new era where people are not just defined by their past actions but by their potential for change.
Their relationship could develop slowly. At first, Toga might be curious about Izuku because he's so different from the others she's known. Izuku would be cautious but also see that Toga is more than just her villainous reputation. They might start by having small conversations, gradually learning about each other's hopes and fears. As they spend more time together, they could develop a deep bond. Izuku might inspire Toga to be a better person, and Toga could give Izuku the confidence he needs in a world that doesn't believe in the quirkless.
Toga is still alive in the manga. The creators haven't decided to end her character's journey with death. Usually, such major plot points are well-signaled and haven't happened for Toga so far.
Perhaps 'y' is a relative of Harry's that was thought to be dead. This relative could have a unique magical heritage that they pass on to Harry, making him even more powerful. For example, if 'y' was a distant cousin from a line of powerful seers, Harry might develop some precognitive abilities.
