I assume your in middle/high school?

I'd say choose a different topic. It is something you love and you will have fun doing it, no question, but ask yourself if you really want to talk about this in front of your class. I wouldn't have wanted to do that and I loved my class back in the day. But there's bound to be some asshole who makes fun of you and the rest will join in because that's what humans do. Which sucks for you and your presentation.

If you think your class is different, okay. But remember, something like Sentai can be hard to evaluate for a teacher. The presentation itself matters a lot, true, but the topic plays a role too. And using an entertainment show could also tick the teacher into giving you a bad grade because he thinks the topic is useless. Not that it is, but the teacher could think that.

I would advise you to come up with a better topic. Sorry.
