Rika Matsumoto, the 31-year-old daughter of Aum Shinrikyo founder Shoko Asahara, who is on death row, realizes her father's notoriety has made it impossible for her to live a normal life.

Instead, the third daughter of the guru has come forward in public with her own story, published in a memoir on March 20 — the 20th anniversary of the doomsday cult's 1995 sarin gas attack on the Tokyo subway system.

Asahara, 60, whose real name is Chizuo Matsumoto, has been sentenced to hang for a number of crimes, including masterminding the Tokyo sarin gas attack, which killed 13 people and left more than 6,000 injured.
