Comments
Ran really really hopes her purse is never lost or stolen.
Ritsue Tetsumoto reduces this to a comb and the cigarettes.
Yoiko Ijima generally has the cigarettes along with some dumb slutty-looking cigarette holder, more makeup than Michiru, leather polish and a little rip repair kit for her arcane gear, handcuffs, a foldable disposable plastic poncho, and several small (and very sharp) pen knives.
Tsukiko Otonashi usually has makeup, sun screen (important for her), a pair of reading glasses, some cough medicine and a little bit of Advil, some pens and paper, her checkbook, a few pieces of chalk, and a small moleskin notebook full of really quite surprising things if you can read her hand writing.
If one finds the concealed zipper keeping a hidden storage layer closed, there's a set of metallic needles and picks, a slim USB key, a small worn picture of herself with her sister and a newer picture of her and Naomi.
Jason's Pockets - His wallet holds his PR Card, a variable amount of yen, his driving license, his private detective license his gun license and a couple credit cards for emergencies. Hidden deep in the folds of his wallet is a worn out looking photograph of his family. He also has a battered looking metal card case with his business cards, the newer one for the Golden Boar and an older one when he was just a private detective. Despite the fact that he has a smartphone, he keeps around a notepad, a pen a couple pencils. A pack of cigarettes and a lighter live in his shirt or coat pockets. He also has his apartment key, key to his Hilux and keys to the Golden Boar attached to a carabiner hooked to his belt loop.
Raj's Pockets - He has his wallet with yen notes, credit cards, his working visa and his Indian ID. There's also pictures of his family and a recent one of Arisa. He also carries keys to his apartment and a motorcycle.
Leigh Anne - travel-sized medical case, compact mirror, a cellphone, eyeliner, lipstick, a small bottle of cinnamon-scented perfume, wallet, checkbook, Sig Sauer P226 pistol, a small tin of dog treats for Brutus, Altoids.

Shinsuke Kusagawa has in his pockets: His wallet (contains ID, Visa card, 20000 yen, and a picture of his sister), notepad and pen, an mp3 player with earbuds, his smartphone, a comb, key ring with a charm that resembles the final boss in a popular Final Fantasy-style RPG and anime (contains dorm key, house key, and old house key), and his silver pocketwatch.
