Ema and Evan are identical twins who are the polar opposites from gender to ambitions in life. Evan is the older twin of the two and has a very weird affection towards his younger sister. Ema loves her brother dearly but sometimes she worries about him because his main occupation is a stuntman and fight coordinator for action to horror movies. When their father Rintarou Hinata gets married to Miwa Asahina they are are surprised to inherit thirteen brothers got their small family. Evan is a hard-working sarcastic weirdo and Ema is a bubbly airhead when it comes to relationships.

What happens when these twins catch the interest of their brothers ? Will they survive the Asahina household?

I don't own the Asahina brothers characters nor the pictures but I do own the main character and the twisted plot of this story.
