An unnamed 14-year-old girl who is physically abused by her parents, sexually abused by her teacher and bullied by her classmates decides to commit suicide, but is stopped by an unnamed 26-year-old man who always wears a mask. She decides to run away to live with the man and begins calling him mister or "Onii-san". He gives her the name Sachi, meaning happiness. The police treat her disappearance as a kidnapping, and begin searching for the two. They make a pact that if they can escape from the police they will get married, but if they get caught they will end their life.


Mister (お兄さん, Onii-san)
Portrayed by: Shuhei Uesugi[1]
This character whose name and age are unknown is a man who always covers his face with a mask, and is notable for his silver-colored hair. He first appears as Sachi's "stalker"—he took a lot of picture of her and put them on a wall at his home. After saving Sachi from committing suicide, he decided to give Sachi a chance to "taste happiness" while doubting whether what he does—kidnapping her—is the right thing to do.
Sachi ()
Portrayed by: Inori Minase (TVCM),[3] Anna Yamada (TV series)[1]
Sachi is a 14-year-old victim of her abusive parents and was bullied by her friends at school. Sick of her own life, she decides to end her own life before the "older brother" saved her life. Her current name is given by the older brother, and the kanji of her name comes from the word "happiness," which Sachi always adored.



As of July 2019, 6 compilation volumes have been released.[4]
