Harukaze Sekai no Mahou Shoujo -Eiyuu no Musume to Kyokou no Himegimi-

It's a world of the near future.
The gossip of a town is becoming a reality.
There is a strange phenomenon happening.

The gossip becoming real has caused strange creatures to exist.
To protect humans from their own wild delusions and loose tongues,
a single magical girl must brave the battlefield...
