Mahou Shoujo no Ani ~Heta na Uso to Furyou Shounen~

It took three hours from Tokyo, and involved changing trains on several different lines.
The only thriving area was in front of the station, and the rest was just dirt roads as far as the eye could see - a typical rural area.
That was our new home.
I was a transfer student who had moved from Tokyo to this rural area due to my father's work.

Fortunately, I was blessed with great classmates at my new school and enjoyed my days.
Then, one day, a few days after we moved.

I returned home from school and opened the front door to find my sister lying there, covered in wounds.
I quickly picked up the phone, trying to call an ambulance...but someone stopped me.
I turned around to see my sister, who was supposed to have collapsed.
I started to ask why, but my sister's voice drowned me out, saying, "It's nothing."
As I treated her wounds, I pressed her on what had happened.

Most of the injuries were scrapes and marks from beatings, clear evidence that she had been harmed by someone.
I was thinking that I might have to report this to the police when my sister said,, "Well, you see... the truth is... I'm a magical girl!"

Her eyes were unfocused, and they were clearly filled with anxiety and fear.

What exactly was my sister trying to hide, making such a lame excuse?
At that time, I still didn't understand anything.
