Following that, Genya and Sanemi decided to protect their family together. They father's death brought out a better living situation for them, however, that was not enough to sustain the family.

One day, when it was really late at night and Shizu was yet to return home, Sanemi and Genya could not bring themselves to sleep. Hence, Sanemi went out to search for their mother, while Genya was to stay back and take care of the other siblings.

After some time passed by, the Shinazugawa siblings were worried when a person knocked on their door. While Genya's younger siblings believed it was their mother, he suspected that the person was someone dangerous. Right after, the person on the opposite side of the door tore it down and cut down all the children, except for Genya, who only got a scar.

Genya could not see who had attacked them and was terrified when Sanemi came to his rescue and pushed the attacker outside the window. Genya, seeing his injured siblings, ran out to fetch a doctor when it was finally dawn and he could see a blood-soaked Sanemi in front of their mother's dead body.

The person who had attacked them was their mother who had gotten turned into a demon. However, Sanemi could not see it due to the darkness and killed his mother while protecting his brother. But only when it was daybreak Sanemi could see who he had killed.

Even Genya, who at the time was too emotional due to the events that had occurred, could not understand the situation and ended up calling his brother a murderer despite the fact that he had protected him. This eventually led to them drifting apart as a family.
