Kigurumi Guardians Graphic Novel Volume 04 (Mature)

"Hakka's second year of middle school was dull as it could be, until a suspicious cow mascot ('kigurumi') shows up in her room, holding a sign that reads, 'My Name Is Ginger.' But this isn't (just?) a stalker, it's a magical being that's come to convince Hakka (and her friends) to become Guardians, and save the world! Hakka is understandably confused, until she's suddenly attacked, and a beautiful young man leaps in to save her. Can this handsome knight and the weird kigurumi be one and the same?"
