Hello, Today's pick is "Hekikai no AiON" a Shounen Action Fantasy manga about Tsugawa Tatsuya a High School student that one day meets a strange girl who seems to enjoy being bullied but actually is hunting for bugs that control humans and influences them to do terrible things.

Description:

Tsugawa Tatsuya just lost his parents in an accident... but he's trying not to let that keep him too down as he starts high school.
While trying to obey his father's final wish for him to become an upstanding man, he ends up helping a girl who was being bullied. Despite her exceedingly cold nature, he just can't leave her alone... which may not necessarily be to his benefit, as he ends up getting wrapped up in a world where things like parasitic mind-controlling bugs exist...
