A typical plot device could be the school setting. In the My Hero Academia universe, school is a big part of the story. The OC could be a new transfer student, and the harem forms around them as they navigate through classes, training, and exams. Social events like the school festival are also great for plot development. It gives the OC and the harem members a chance to interact in a more relaxed setting and show different sides of their personalities. And misunderstandings are quite common too. For instance, the OC might be seen helping a villain accidentally, which causes drama within the harem until the truth is revealed.
Often, a prophecy or a special mission is used as a plot device. The OC could be the key to fulfilling a prophecy that will save the hero world, and the harem members are there to support them. Power-ups are another device. The OC might gain new powers during a crucial moment, and the harem reacts to this new development. And let's not forget about rivalries. There could be other characters who are rivals for the OC's affection or for their position as a hero. This creates tension not only between the OC and the rivals but also within the harem as they try to protect the OC.
One common plot device is the OC having a unique quirk that draws the attention of the harem members. For example, if the OC has a healing quirk, it could make them valuable in a world full of heroes and villains. Another is the introduction of a common enemy. This forces the OC and the harem to work together and strengthens their relationships. Also, the OC's backstory often plays a big role. Maybe they come from a poor background and their determination to succeed in the hero world despite that attracts the harem members.
Perhaps the OC has a hidden past related to a villain organization, and the harem members are initially suspicious but as they get to know the OC better, they realize there's more to the story. This could create a lot of drama and conflict as the OC tries to prove their loyalty while also dealing with their growing feelings for the harem members.
First, give your OC a distinct personality. They could be shy and reserved but with a hidden strength, or super confident and a bit of a troublemaker. Next, design a unique quirk. It could be something related to nature, like controlling plants, or a more mental-based quirk like mind - reading. For appearance, think about what would make them stand out in the My Hero Academia world. Maybe they have colorful hair or a really cool costume. Also, consider their backstory. A tragic past can add depth, like if their family was killed by villains and they are determined to become a hero to avenge them.
