Just like Sekiko, Iris is super good.

She comes in a big ass box and has shit tons of parts, 90% of them can fit on her all at once, with a couple pieces like an armored head, partially armored head and a completely flat alternate chest plate.

Her sub arms in her binders come in two varieties, one folded for storage and the other fully extended. The armature that connects them to her backpack can rotate, and sits at 45° meaning the sub arms can get very good movement despite not having any bicep swivel.
