Kira has learned about the past, present, and future of Sakamichi from the last thread:
>Nogizaka46's 5th generation member Nakanishi Aruno came down with a certain infection called stomatitis. It affects her inner cheeks and tongue and is caused by irritation or allergies to the mouth. She won't be talking for a while.
>Sakurazaka46's 3rd generation member Endo Riko was teased for her natural habit of laughing while covering her mouth on the latest SokoSaku VR segment
>Another 3rd generation member Murai Yu eats ramen too loudly (which demonstrates that a hidden camera episode is needed to see the rowdy and mysterious behavior of Sakurazaka's 3rd generation members)
