mirio loses his quirk

Yes, he does. But it takes some intense plot developments and challenges for him to do so.

Mirio eventually gets his powers back. This occurs after a series of challenging events and character growth that leads to his restoration.

It could be Voldemort. Voldemort might use Harry's love as a weapon against him. He could either kill her or turn her against Harry. Another possibility is Draco Malfoy. Maybe Draco tricks Harry's love into thinking he's a better choice. Or it could be a new, unknown dark wizard who targets Harry through his love.

Mirio survives in the manga. The storyline doesn't have him meeting a fatal end. His character continues to play an important role.

In fanfiction, Izuku often has unique ways to cultivate his quirk. One common scenario is that he focuses on intense physical training. Since his body was initially not as strong as it could be to handle his powerful quirk, he might do a lot of strength - building exercises like weightlifting and running. This not only helps him control his quirk better but also increases his overall combat capabilities.

Well, Deku does lose his quirk. However, this event leads to new developments and challenges for him. It's a crucial plot twist that adds depth to the story.

No, Bakugo doesn't lose his quirk in the manga.

It might also change his relationships with other characters. His friends could be both amazed and a bit envious. And his enemies would start to see him as an even greater threat. For example, Bakugo might feel more pressured to compete with Izuku who now has an additional powerful quirk.

Maybe he starts to train with one - armed techniques. He could learn from other one - armed ninjas if there are any in the fanfiction world. His friends would also play a big role. They might encourage him to keep going or help him in his training.

His friends, Hermione and Ron, would surely help. Hermione with her intelligence and Ron with his loyalty.
