What would happen if Zenitsu had an older sister? How will this impact the story? And how will she affect her piers? This is an AU where Zenitsu has an older sister who also knows how to use thunder breathing. I noticed that all anime inserts are usually an x character story, so I wanted to do something different. So this story will b following the canon story, or at least I'll do my best to have it follow the canon story.
