Nintendo Dream ran a reader poll for Fire Emblem: Three Houses and published in vol. 306 (released August 21st). I translated some of the results and comments below!
The poll was conducted between July 25th through August 1st 2019 (Note that the game was released July 26th, 2019).
Note: I purchased the Nintendo Dream volume that included this poll with money received from your kind donations. : ) This is all done on my free time, and takes awhile. It can be a lot of work, but I do hope you enjoy!
