For people who still might check this journal:
(There will be many spoilers for Fruits Basket here.)
A combination of reasons. But in order of importance:
1. It's been way too long since I read Fruits Basket.
That's not to say I haven't read it at all while I've been in Japan. I have all of the manga with me, but just don't have the time to thumb through and translate them at the same time. While I was in America, I read up to volume 12 in English, and except for some skimming to find certain scenes, I haven't been able to read those ones since. However, since I got to Japan, I was able to find scanlations of volumes 13-17 online.
For those who don't follow Fruits Basket the manga... Volume 11-12 is a big turning point in the series. Before this, it's exactly like the anime was. High on cute relationships and funny personalities as Tohru meets all of the Juunishi, with the occasional appearance/threat of angry Akito. Fruits Basket doesn't really give a lot of time to show these personalities bouncing off each other, very quickly the series takes on a focal point: Tohru decides in volume 12 that she wants to break the Juunishi curse.
After this, the story sorta branches in two:
a. Part is dedicated a hell of a lot to detailing Yuki's new relationships with the Student Council. Not that I have anything against the "Student Council Arc," but this side of the plot comes completely out of left field. This is also mixed with a lot of flashbacks detailing Yuki and Kyou's (but it's mostly from Yuki's pov) childhoods. (And wow, Yuki is made of strong stuff. He was basically kept in a room and tortured EVERY DAY since he was 5-6 until he reached high school age and got to live with Shigure.)
b. The other is Tohru actually trying to find out more about the curse. This involves talking with Kyou's dad, Kureno, and her meeting Rin.
While when I was reading it, I was enjoying it. And I still think it's interesting... it's not the sort of manga plotline that was making me think: "Wow, this would be great to roleplay." That is, it turns into more of a private drama amongst the Sohma family with even Tohru becoming a little more passive. Not the sort of thing you can rp easily at a multi-canon Zombie Camp rp. (I think all of the furuba characters may be struggling with that a little.)
Maybe I could've done my best to focus on the first volumes that inspired me to app Yuki, but it's hard to put energy into translating manga you've already read when there's new volumes you haven't read. Overall: I had gone without reading the first volumes for too long, and though I still enjoy and have been followig the Fruits Basket story now, it's just not the sort of story that easily inspires rp.
2. Kyou and Tohru dropped. [slash] I ran out of energy.
I list this as a reason without any bad feelings whatsoever to the former Tohru and Kyou-rpers. It's easy to run out of time/energy for rping anymore (that's why I'm writing this, afterall XD;). However, when I first apped Yuki, there was a Tohru and a Kyou already at camp. I never thought of the possibility of "hey, there's a possibility one or two of them might drop..." Although when it did happen, I wanted to continue. I was thinking: "Even without other characters, I can rp Yuki by himself." And even then, he wasn't by himself: Ayame, Shigure, and Haru (who was just joining) were there too. (Though, the times that were really fun with Yuki involved some amount of traditional-like furuba interaction with Kyou and Tohru.)
But, I realized that recently I was following into the same pattern... practically the only reason I posted/commented anymore was at Haru-rpers urging. When I reached that point, I knew it was a good time to drop...
Those're the main reasons.
1. Lack of ideas outside of Fruits Basket canon.
One of the last things I rped with Uo was her meeting Wednesday-turned-into-Death. And Death told her about how Kyoko died. ("She was pretty pissed.") It was the first time I had been motivated in a while to rp as her... and I knew right away: that was a huge problem.
If the only way I could have a fun/eventful interaction was to somehow steer it to a talk about furuba canon, rather than rping her personality, I knew I was in trouble. Because that was going to get old, quick. I knew I'd run out of ideas.
2. Trouble developing relationships.
I'm not saying Uo didn't have friends, or couldn't talk with people. But, Uo's chief relationship outside of her canon was with Chizuru, who at first she beat/punished for being perverted, then when Chizuru/Chisame became a couple her attitude softened a *little*, and eventually it turned into a sorta friendly rivalry/opposition. "I hate you." "Aw, I know you do. ♥" "Hee."
But I knew there was a problem when I made a comment asking for Chizuru's opinion of Uotani, and it really felt like the opinion could've been written the exact same a few months ago.
Maybe I should've judged that as a good thing... Tohru/Uo/Hana's relationship never seems to change in furuba, but I came to a similar conclusion if I couldn't change anything, I wouldn't be able to keep up the same joke over and over.
These reasons do overlap a bit, between Yuki and Uo. Of course there's no steadfast set of reasons why I dropped them, but I felt like providing some explanation for those who might've been looking for it.
On a final note:
Perhaps in the future... when I'm no longer in Japan... these problems won't seem as a big as they do now.
That's all I'll say. XD
