There's a flash of confusion and annoyance at being interrupted, then sympathy.  "Hey, all good.  Partner not around?"  Handshake?

Handshake.  - eurgh, is that what it always feels like?  She flinches, obviously startled.  " - sorry.  Guess we don't - work."

"S'okay.  Good luck!"

Maybe this Amazonian brunette she's about to pass by would be better?

...she's trying not to notice how attractive anyone here is because the whole idea of guiding is already weird and vaguely uncomfortable enough without that extra layer on top of it but wow hmm uh huh yep okay yeah.  " 'Scuse me miss but I need some guiding and I don't have a partner around, can we check - ?"

Without speaking, she offers a hand.  Her other hand signs - how's Parry's Dungeon Sign Language?

Uhhhhhhh nonexistent.  She - okay handshaking seems stupid if it feels like that most of the time, can she just sort of brush her hand against hers - ?

Sure.  Unfortunately, Silent Tall And Also Big Girl's message will be a mystery for the ages.  She sighs a little when Parry's incomprehension becomes evident.

... it feels meh.  Not like 'nothing', like there's a sense that Parry previously did not have that is signaling 'meh' at her.  Also, it feels like the woman has a lot of something, in addition to her physical stature.  It's a bit Oobleck - metaphorically not like rain, metaphorically not like snow.  Presence?  Something.

Huh.  Okay.  Well it least it doesn't feel horrible and gross every single time she can't guide with someone.  "Thanks."  She'll hesitate for a second in case Tall And Also Big speaks up, but she can't actually stop walking, and in a minute she's walking away.

She actually taps her throat twice, then firmly shakes her head 'no', and looks at Parry apologetically.  But she doesn't slow Parry down any.

She nods acknowledgement.

She keeps trying.  She eventually picks up the phrase "compat check," and starts using it adequately correctly, but she does not really become any more comfortable or less stiff about approaching strangers in this context.  ...Once or twice she just stops trying for a little while and circles the room for a minute, because honestly it is better to just have to walk in a big circle for a minute than to try another god damn time to get somebody to guide her.  But she knows she's gotta take care of this.  She dives back in.  She hates it.

Around noon an esper bustles into the room, waves at everyone, scoops up a plateful of bite sized goodies, and starts canvasing the room.

Oh is someone else looking for guiding too.  "Hey I can't stop walking but can I get a compat check - "

"Yeah, of course."

Fistbump. Or hand brush, whichever seems to the vibe here.

 - she flinches away and awkwardly breaks eye contact, after a moment of letting their skin touch.

"Huh, was it bad for you? It was good for me. Not great but better than nothing."

"No, it - felt nice."

Oh wow she was so caught up in how much she hated trying to get to this part that she forgot all about how much she was going to hate this part.

 "Are you new? I'm Kuroko, nice to meet you."

She will make a hand readily available but not push the issue.

She looks at the hand, and how readily available it is.  She needs guiding, she should just not say no to a good thing.

"I'm - so you can tell I'm gay, right - "

From the everything about her.

"Yeah I sort of guessed. I'm not, but like it doesn't have to be weird."

She maybe shouldn't have said the second sentence, but backlash.

...she will not make eye contact just yet but she will take Kuroko's hand.

Oh that feels nice.  It's weird for just touching somebody's hand with her hand to feel that nice.  Why are all the cute ones straight and/or not backlash compatible with her hey shut up?

"I'm Nitro," she says.  "...I guess there's already a Nitro so I gotta come up with a different name but that's what I'm goin' by now."

Handholding

"So many good names are taken. That's part of why I ended up with one in Japanese. Also because I had an anime phase."

"What's it mean?"

"Old fashioned Japanese stagehands. They used to wear black, so that people knew they weren't part of the story and to ignore them. The story goes that one time somebody wanted to have a ninja assassinate a character so they had the ninja character disguised as a stagehand until the twist. Then a lot of people copied it, and that's why stereotypical ninja wear black. It's because my power lets me be unnoticeable. It's not technically invisibility, it doesn't work on cameras, it just stops anything I don't want to notice me from registering me."
