Denki Kaminari remains alive throughout the manga. The author didn't include his death as part of the narrative. His character has continued to play an active role in the story without facing such a fate.
One common theme is growth. Both characters often grow as individuals and in their relationship. For example, they might learn to overcome their insecurities or past rivalries. Another theme is the power of friendship evolving into love. They start as classmates or rivals, and then their bond deepens into something more romantic.
His aggression might become more unhinged. Without the moral compass of the hero side, he could be more willing to use excessive force. He'd still be competitive, but now it would be against heroes instead of his fellow hero trainees.
Bakugou could use his words. He might tell Deku that he believes in him. For example, he could say 'Deku, you may be a nerd but you're a strong nerd.' It's a backhanded compliment but it shows he has faith in Deku.
Definitely not. Bakugou is still alive and kicking in the manga. The creators have kept him around to drive the story forward and engage the readers with his dynamic personality and actions.
Kirishima would probably support Bakugou. He respects Bakugou's strength and no - nonsense attitude. He also doesn't like Mineta's pervy behavior, so he might think that Mineta deserved it. Kirishima would see Bakugou's action as a way to keep the class in line.
One popular 'deku x female kacchan fanfiction' might be 'A New Bond'. In this story, Deku and female Kacchan start to see each other in a new light after a shared adventure. Their relationship develops as they face challenges together and learn to understand each other's strengths and weaknesses.
