Work makes me productive, apparently.
First level
Tsuzuki (essay goes
here)
Second level
The people Hisoka cares most about and trusts in camp, after Tsuzuki:
Elphaba
Naminé
Francescu
Second sub-level
Hisoka cares about and trusts these people, but not quite to the extent of those in the second level:
Rikuou
Kazahaya
Ryuuken
Hiro
Kisa
Simon
River
Tot
George
Himejima
Third level
Hisoka likes and cares about these people. They have the potential to move up into the second level (or sub-level):
Coraline
Stellar
Kon
Buffy
Rin
Kio
Ken
Omi
Death
Delirium
Momoko
Ari
Fourth level
Hisoka probably hasn't spoken much with these people, but he has a generally positive opinion of them. I tend to refer to it as the "neutral positive" level:
Anne
Akito/Agito
Ichigo
Arsenic
Kaylee
Hatsuharu
Fllay
Shinn
Yzak
Cher
Yachiru
Hanatarou
Bart Allen
Raenef
Megan
Obi-wan
Clark
Chloe
Minagawa
Aziraphale
Atsuko
Fifth level
Hisoka's mostly neutral toward these people, usually because he hasn't spoken with them enough to form a real opinion. He has a better (or worse) opinion of some of them than of others, but for the most part, he's neutral:
Wolfram
Robert
Heine
Ishida (mostly because Ishida dislikes him, not the other way around)
Ikkaku
Tobias
Rey
Near
Lady
Ying
Cal
Rue
Swift
Hanajima
Luna
Gon
Sayo
Haruhi
Itachi (unnerves him slightly, but otherwise neutral)
Gene
Ranma
Lupin
Akiha
Cheri
Dumbledore
Sixth level
Hisoka dislikes or is annoyed by these people:
Emilio (Hisoka is closer to neutral toward him than the others, but he's still annoyed by him)
Dark Helmet
Butthead
Miscellaneous
People who don't really fit in any other level:
Saya, Yuma and Ayame go in the "Hisoka likes them perfectly fine as long as they stay a safe distance away and/or stop talking about his appearance" category 8D
Nishi's kind of creepy! :D
Sanzo's probably the counselor Hisoka trusts and respects most after Tsuzuki, although they don't talk that often
...and I think that's it. If I've forgotten you, feel free to poke, although most people probably fall under the fourth or fifth levels. And if you want clarification, feel free to comment as well!
