A different world where demons are rampant and murderous. Olivia, a female knight, lives with her apprentice Noah, an animal eared child. A tale of a master and apprentice growing up, adventuring and being healed by the strong bond between each other.

Ishikawa-san, the girl in the neighboring seat, wears a mask no matter what she's doing. One day, Izawa catches sight of her face without a mask and wants to see it more and more... Masked or unmasked, it's a cute romantic mask comedy!

(Synopsis translation by Shurim)
