I'm sure you know Momoe also busted out some English at _Road To Graduation 2019_ and again during "Blue Winter". Momoe is VERY smart. I wouldn't be surprised if she turned out to be a literal genius …unlike "Genius" KANO who, to her credit, is also trying to learn English. So is GUMI -- in fact GUMI writes most of her Notes in English. Her grammar is bad but not to the point you can't understand her. I'm so proud of them for trying so hard.
