This episode was spectacular, especially the ending (Haruka in a Santa Outfit is especially fan-service indeed
)
I give it a 9/10
Seems like the endings always take to the time-limit of "Christmas Time" (never played the VN so wouldn't know myself.) Now we get a underclassman arc, with the "cute" yet "weird" voice
I wonder if Miya will appear more since she is best friends with the new main character.
