Permissions

Character permissions:
Combat: Go for it, but Itsuki's trained in martial arts, so it might go either way. If things get serious and she's in real danger, don't be surprised if she shifts to Cure Sunshine (if able, depending on the game).
Flirting: Itsuki's a little oblivious, but go for it. More obvious actions will get noticed more readily, of course.
Hugging, kissing, etc.: Varies with CR, but the costs are pretty low. In general, go for it if you know her at least a little. She might be a little surprised, but probably not angry. Ask if unsure.
Injuries: In the course of combat, sure. During events, probably. Just because... ask first.
Death: Ask first.
Mind reading, telepathy, etc.: Go for it. Itsuki's dirty laundry (at least, what she has to start with) went public quite some time ago in her home canon, so she doesn't particularly mind. Information on her past, her home canon, and most relationships is generally free. Aside from her one big secret, she'll also resist (if able) disclosing relationships that will be a big problem if revealed. See Special below for a particular thing you might pick up.
Memory erasure, mind control, etc.: Ask first. That said, I'm pretty sure nothing Itsuki has gives her resistance to mind-affecting abilities.
Special: Itsuki has a semi-secret identity as Cure Sunshine (if she's gotten it in-game). It likely won't stay secret for very long in a closed community, and especially not if she needs to use it, but she takes pride in keeping the secret for as long as she can. Mind-reading powers will meet mundane resistance if you try to dig for it. Itsuki's entire manner changes while she's in Cure form, and she's not readily recognizable unless you have a specific thing to look for. Expect negative CR if it gets out and she determines you're the cause. Depending on the game, Itsuki is doing - and more importantly, thinks she's doing - a decent (but not at all perfect) job of passing as male, so if that's what you're expecting, you might be in for a shock.

Gameplay and RP permissions:
Backtagging: Sure. I am really terrible at consistent tagging sometimes - if it's been more than a day or two, please prod me (Plurk works best) and we'll get set up.
Threadjacking: Itsuki is someone that rolls with the punches pretty well, so I should be fine with it, so long as we don't start talking about fish in the middle of a fight to the death.
Fourth-walling: Should be fine, unless you've got a big bombshell, in which case you might ask first.
Avoid: Nothing I can think of here.

To ask questions or to ask permission for something I listed as "ask first", either message this journal, ask me on Plurk (eternities) or comment here. Comments are screened; anon is on but odds are pretty good you won't need it here. Replies to comments, and their top-levels, may be unscreened to reduce repeat questions; if this isn't kosher, please let me know when you comment.

Ahaha, I remember when I made this a long time ago. Time to give this a little bit of an update... Anon is now turned on after two years, so have at it. Anon is on and comments are screened; I tend to unscreen comments when I reply to them to reduce repeat questions or crit I'm already aware of, so please be aware of this. Alternately, let me know when you comment if you'd rather I only unscreen my replies, or keep the whole thread screened.

This journal is in play at voidtreckerexpress, and has previously been played at queenofheartsrp, dramadramaduck, mallowhallow, mylittlejamjar, omegafriends, and cityofariel. If you're looking for the character that looked a lot like Itsuki that was in srwug_alpha_rp, you want sunshine_maiden. I use one journal for Itsuki whether she's presently a Precure or not, so if you're trying to identify a tag, it will always be from this journal if it's from this Itsuki.
