Momoka's wounds ?
So i noticed that Nishizono (the cute priest in love with Bart) had some bandages on her leg. I first noticed when with her bestie-friendly priest he tried to heal her wounds to see if healing magic worked in this world. They were in her house (i think), she took off her long socks there was some big bandages on her legs, but I can't find the chapter. And they never said how the hell she got those wounds, or I missed it.
You can also see them on chapter 30 :
Do you guys know how she got them ?
