What series can fit into the Ranma universe with the least amount of prompting?
For example Sailor Moon and Urusei Yatsura are often depicted as being in the same universe. there doesn’t even have to be a crossover often its as little as a character says you think Nerima is bad have you heard the rumors about Juben and Tomobiki.
As i mentioned in the other thread, Nyan koi most certainly works and is pretty darn suitable even.
The RailDex-verse works, but beware how much more complex everything can get and that it's not a flawless fit, especially with how much darker the background world is.
Aho-girl. No seriously, there's nothing blatantly magic or "super martial arts" in it really, mostly... Buuuut, main girl might as well be one with the level of durability and stamina she has, and there's a couple of "ladies" who could compete with Happosai in the art of stealing underwear from people while they're wearing it.
Fuuki and Yoshie. Yoshie especially is perfect for Ranmaverse, as she's trying to make certain that her daughter gets married to the main male character, for the sake of her retirement(now where do we know THAT phrase from...). Because her daughter is the "aho" in the series name and according to her, guaranteed to never achieve anything(including being able to secure her future). AND she has a "nice" mad laughter a´la Kuno Kodachi style.
And said daughter in question, is an EXCELLENT crossdresser.
This scene is hilarious and shows off the underwearstealing. AND when dear mum loses, she ends by saying that she needs to start training again. So, utterly and totally perfect for crossing over with Ranmaverse. It's like it was made for it.
https://www.youtube.com/watch?v=yK6Hq4wnbKsSchool Rumble probably works perfectly.
Rosario to vampire can work with some stretching.
Baccano/Durarara the same.
Henneko could probably be added to the Ranmaverse "as is". Magic causing "issues" is like taken from Ranma.
Plastic nee-san, lol... If only for this insanity:
https://www.youtube.com/watch?v=mYqeVT9pQBg Ramen fighter Miki. Just no question, it's frickin perfect. A waitress and delivery girl who is specifically listed as "overpowered main character", "hotheaded", "martial artist".
Love Hina probably works and fits in well with minimal adjustments needed.
Ben-to. Fighting savagely over halfpriced food? Uh yeah, kinda very easy to slot in completely unchanged.
If you can’t place it in the universe how would you change the series to fit.
Pretty much any series that is focused on martial arts, trouble with magic/curses, or simply just "high school" or RomComs can be mashed together with the Ranmaverse quite easily and "logically". It's more a matter of which ones you WANT to use rather than which ones you CAN use.
For example, Bamboo blade, focused on kendo competition, all it would take would be to stretch the teams abilities just enough that they can end up in a competition with Kuno without instantly losing and you have a fit.
