.... 10, not 5. Oops.
[because I'm bored. ICly, things he doesn't want:] 1. Byakuran and Hanatarou's fall-out. 2. Akito's depression. 3. Love. Takes up too much time, and they can always leave suddenly. :/ 4. Spitfire and Sano's fall-out, Akira's disappearances, Ed's depression, etc, etc. 5. Wanijimas' (and any friends) magnet for trouble.
[OOCly, aka things he really doesn't need, but doesn't understand] 1. Dying/ X/ paranoia, wut. 2. Overworking, attempting to be an adult, not looking after (or caring about) himself. 3. Putting off the Byakuran problem. 4. Aki leaving/ Ikki leaving/ growing apathy to people. 5. Kaito's obsession over Akira/ seeing it first-hand as much as he does. Bad for a teen to be around 24/7. D:
