[If she's being honest, Lisa has no idea how she's going to cover Koi if they need to keep moving - Cinnabar is a very hard target given they're also probably immune (or at least resistant) to poison, since that's their entire thing, so it's probably going to shoot at her. She can't help attack it if she's going to have to concentrate on defense, so how-?

Someone else dropping in almost literally is a godsend, and she lets out an audible sigh of relief. She doesn't entirely know who this is - there's no time to ask or verify - but they're attacking the Nocta-thing and that's enough for her. Immediately,
after a one-handed wave of thanks, she changes her tempo to a more musical series of tones, and a red comet bursts from her bass, toward one of the eyes. The shot sails true, but at the last moment the thing lurches just slightly - maybe to get away from this other Dreamer? - and it sinks largely uselessly into the sludge. Not waiting to see if she scored the hit, Rhodonite bends down to Koi to help her stand, but not without a gentle hand on her shoulder for a moment before reaching to haul her up. She feels off standing down here... if they stay, she won't be able to keep moving after much longer. She doesn't know what it is but she can feel it.]

Here, come on up. Are you okay? I don't want to stand down here where we might get hit if this thing shoots at Cinnabar-san and misses. [A beat, and her confident expression melts away into something not far from the look on Koi's face.] Well. No, you're not okay. Neither am I. But... if we give up here, who's going to save Hanako-kun? H-he needs us, right? I'm not... going to leave him here by himself.

[......she really needs to work on her Friendship Speeches, but this might work for now?]
