Soul Perfume (Sora) - A device that looks rather a lot like an ornate perfume bottle, with shiny gold accents. Normally houses the AI POTPOURRI, but he doesn't seem to want to come out here. (And, indeed, he won't appear in MidSyn at all.) Helps Sora manage her magic and that she normally uses to pilot Desu Itsuki; without it, most of her magic is too hard to use. While holding her Soul Perfume, Sora can take on her hardlight suit and gain a whole bunch of extra power, along with a lot more protection. Another pilot could theoretically use Sora's Perfume to transform, but it wouldn't work very well. Other characters can't use this.
Ring - A small ring, woven from very strong metals in three colors. It's actually a collection of scraps from the remains of the Claimer-class units after the battle with DUNE: cherry blossom pink from Desu Tsubomi, ocean blue from Desu Erika, and sunshine yellow from Desu Itsuki. A memento of what Sora left behind: her teammates, and her partners. Wearing it is habit at this point; one of her easier-to-spot nervous tells is that she'll start messing with her ring, as it's a reminder of things gone wrong, too.
From Eros:
Computer (Sora) - A small, mildly portable computer, given by Rachel as a gift for good service. Sora keeps it in her room where it won't walk away, but she's been known to take it with her. She tends to make faces when she uses it, as even in the post-Impact world, computers were a hell of a lot more powerful than this.
Otto - A small stock of money that Sora keeps in a safe place, carrying a little if she thinks she's going somewhere she'll need it. Everyone needs something, and there is no world where money isn't a universal language.
Aphrodisiac - A small, very well-hidden stash contains three vials of Sora's backup plan if she needs to work off some stress, given by Rachel as a gift for good service. She doesn't carry any, as a rule; no situation requires that much force without careful consideration. Not that this opinion is likely to remain for long.
