Ranma 1-2

Overview
The story revolves around a teenage boy named Ranma Saotome who has trained in martial arts since early childhood. As a result of an accident during a training journey, he is cursed to become a girl when splashed with cold water, while hot water changes him back into a boy. Throughout the series Ranma seeks out a way to rid himself of his curse, while his friends, enemies and many fiancées constantly hinder and interfere.

The series is set in a mid-nineties Earth, albeit a significantly stranger and more magical version. Cursed springs, magical items, and a plethora of ancient martial arts techniques are just some of the differences between our Earth and this one.

Pros
There are several great martial arts perks up for grabs. Copycat Technique is the quintessential stealing techniques perk, Ki Projection is a versatile energy blast, and Supreme Amazon Techniques are both very useful. The Bakusai Tenketsu in particular makes you extremely durable.

The Nanban Mirror is a powerful but fragile time travel item. A very powerful option for a relatively low powered jump.

Barrel of Jusenkyo Water and Mushroom of Time Spores are both powerful and permanent transformation items. The Jusenkyo water is good for giving companions alt-forms while the spores are a cheap way to give other eternal youth that you can cultivate in jump after jump, bringing eternal youth wherever you go.

Anyone you become engaged to that you can convince to come with you can be made a companion at no cost. This explicitly allows temporary engagements. A charming jumper (or one that took the Second Worst Parents Ever drawback) could potentially end up with a great many companions for free.

Cons
The mandatory cursed form could be a turn off for some, especially considering it is a relatively steep 200 CP to avoid it.

The fights get more dangerous and deadly as the series goes on, eventually leading to some battles that destroy mountain ranges. More than that even, there are a whole lot of deadly magical items that are just lying around. The Nanban Mirror, the Cursed Mirror, and the Magical Compact Mirror are items in particular that could easily kill an unwary low level jumper.

The jump is still a WIP (even if it is very jumpable) and it seems unlikely that there will ever be an update.
