More relationship drabbles?
I may have small slices of free time this week! And I feel in a drabble-y mood, I think, or at least in a mood where the long things I have in progress are more intimidating-feeling than my attention span warrants. And this went really well last time, so I think I'll try this format again.

Prompts: You give me A) a character, B) a fandom [which may or may not be the same fandom as A is from], and C) one of the following relationships:

1. rival (Ion, Tales of the Abyss - sugared)
2. partner (Luck, Persona 3 - regicidaldwarf)
3. enemy (Keith, Baccano! - karanguni)
4. colleague (Claire, Persona 3 - mahokiwi)
5. best friend (Akihiko, Persona 3 - lassarina)
6. ex (-boyfriend/-girlfriend) (Aizen, Baccano! - redbird)
7. superior (Firo, Baccano! - laylah)
8. subordinate (Light, Baccano! - mithrigil)
9. mentor (Ronnie, Fullmetal Alchemist - white_aster)
10. idol (Orihime, Persona 3 - mitsuhachi)

...and I will write a drabble which contains A and a character of my choice from B who is A's C. It may be pairing-y or not, depending, but the focus will definitely be on the listed relationship rather than romance as such.

Examples:
You say "Rachel, Baccano!, best friend"
-> I write the drabble where Claire has decided Rachel is now his BFF (and Rachel doesn't mind this terribly).
You say "Ishida, Persona 3, superior"
-> I write the drabble where Ishida joins the archery club at Gekkoukan and Yukari is his senpai.

Preferred fandoms are: Baccano!, Bleach, Persona 3; also good fandoms are: Death Note, Nocturne, Tales of the Abyss. Other fandoms I've played in are accepted on a case by case basis. ^_^

I will take one prompt for each relationship!
