Is there any relationship between Tengo’s mother, Ayumi and Kumi Adachi?
Ayumi had been found dead in a Shibuya hotel room. She had been strangled with a bathrobe sash. She was handcuffed and clothing was stuffed in her mouth.
In the third book Ushikawa said about Tengo’s mother:
“ Before he (Tengo) was even two, his mother had been strangled to
death at a hot spring resort in Nagano Prefecture. The man who
murdered her was never caught….she had been strangled at night
with the belt from her robe, in room at an inn.”
The two women died in same circumstances. That could be just a coincidence. After smoking hashish Kumi Adachi said she had died once and then she reborn. Then Tengo asked her:
“why did you die?”
So that I would be reborn like this.
Then she told him that she was reborn for someone else.
“ The biggest problem is when it comes to being reborn is that
people aren’t reborn for their own sakes. They can only do it
for someone else.”
Then she advised Tengo to leave before exit is blocked. May be she was Tengo’s mother who was reborn for Tengo once again. She also helped Tengo for his father’s last rituals.
