"It's Not Wasteful, Otherworld Summoning"

It seems I ended up being caught in an accidental summoning. When I tried to help a little girl who was about to be hit by a truck by jumping in front of it, a magic circle appeared at her feet. When I came to, I was inside an unfamiliar temple, surrounded by unfamiliar people. Everyone around me was talking to the girl, but my existence was completely ignored. I quickly figured out why, but... this is terrible. Still, since I've come to another world anyway, I'll do things my way! This is a medium-length story about a girl earnestly working as a holy maiden and a boy doing whatever he wants next to her, along with the people caught up in their antics. (It's a complete story in 11 parts. Warning: A certain mother is overpowered.)
