You know, I started doing #FangWatch for fun, but I'm really starting to notice lots of random characters suddenly fang in only one specific situation for no apparent reason. They don't show fang otherwise
It also usually comes after a uwu face too :neocat_uwu:
#FangWatch Takanashi Hoshino shows a #LipFang during this conversation on the school rooftop. She appears to do it when she's acting innocent :neocat__w:
#FangWatch Akira Shinonome from "Train to the End of the World" suddenly becomes catlike and gains a fang when subject to the itchy effects of Higashi-Kurume station.
#FangWatch It's a little hard to spot, but in Sound! Euphonium S3, Kamiishi Yayoi (上石 弥生) [middle] sprouts a little fang when receiving her repaired skirt.
#FangWatch Nice fang!
In Whisper Me a Love Song, Kaori Tachibana, the keyboardist of SSGIRLS, shows her fang in this scene where the girls are shocked.
I guess the first episode is the only time Yasumi shows off her dual fangs. Only one fang here, but both the right and the left are shown at certain instances, but never at the same time.
