Well, the number of story missions in My Hero One's Justice 2 is not fixed. Generally, there are approximately 25 to 35, but this can change based on expansions and patches.
In 'My Hero One's Justice Full Villain Story', the main characters are surely the villains. We can expect to see Tomura Shigaraki at the forefront. His journey to become a powerful villain and his hatred for heroes are key aspects of his character. Dabi, with his mysterious past and his destructive fire - based quirk, is likely to be another main character. Himiko Toga, the blood - thirsty and shape - shifting villain, would also be an important part. There could be other villains too, perhaps those who are part of villain organizations and have their own unique quirks and motives that will be explored in this story.
The story likely focuses on the villains in the My Hero Academia universe. It could show their backstories, motives, and how they interact with each other and the heroes in this 'full villain' narrative.
In fanfiction, Kirishima and Bakugou often have a really interesting dynamic. Kirishima's positive and friendly nature can contrast with Bakugou's more explosive and brash personality. This contrast can lead to some great character development moments in fan stories. For example, Kirishima might be able to break through Bakugou's tough exterior and help him become more open and friendly. They can also be great partners in battle scenarios in fanfiction, with Kirishima's hardening ability complementing Bakugou's powerful explosions.
Accurately writing Kirishima means highlighting his physical and mental growth. He starts off a bit unsure but becomes more confident as he hones his hardening quirk. Mina should be depicted as someone who is not just fun - loving but also a skilled fighter. Her ability to think on her feet during battles, like using her acid in unexpected ways, is a characteristic that should be emphasized.

They have to rely on each other's unique quirks to survive and complete the mission. Kirishima's hardening ability can protect them from physical attacks, while Mina's acid can dissolve obstacles in their path.
