Ranma 1/2

Ranma 1/2, one of the classics of Anime, even if it's story of a literal Gender fluid character is more problematic these days. Even with these problems, it is still a beloved anime with many stories a martial arts, his rivals, his romantic interests and their rivals. With much supernatural elements, like multiple magic items and rare martial arts, it has many oportunities. Upgrading all of the leads from sixteen to eighteen or more, doesn't change too much as long as similar adjustmentys are made.

So with our cast eighteen or older, where does our anime episodes/OVA begin?
