Haimiya-Senpai is Scary But Cute

Synopsis

At my high school, Haimiya-senpai is feared by all and considered too scary. This is apparently due to her intimidating appearance and blunt way of speaking... and those sparkling piercings! The long, gray wolf-cut hair! Even her Kansai accent is intimidating!!!
But for some reason, this scary senpai treats me kindly...?
As "scary" turns into "cute," this scary (heart-pounding) senpai rom-com begins!
