Checked. Wakamo is not mentioned in the story. Arata brings up masks because mouryo characters all wear masks, and mentions that one from 2 years ago switched her masks according to how she felt.

Wakamo isn't shown on the screen, nor is there any supplemental information implying it's Wakamo.

Your logic is a leap? Nothing has ever connected Wakamo and Mouryo. Or do you remember something I don't? This is a far cry from "Wakamo mentioned", especially because in the contexts they're discussing how everyone but Arata in mouryo wears a mask (Arata says she hasn't found a suitable one yet)
I would classify saying "The story mentions Wakamo" as "a bold-faced lie" at best and "headcanon" at worst.
