"Yukari! You are fast! too fast!!"

But she ignores my junior daughter's claims perfectly, and keeps reading aloud more than two hundred questions and answers lists of the science and history.

She is a voiceroid "Yuzuki Yukari"

I really made a great buy.

My daughter has been built up by her, and she could learn the key Japanese chronological table by heart.

I believe that the 6th grade girl, who can response the correct answer in 2 seconds, against the following question after Yukari's voices,

- Partial Test Ban Treaty(PTBT) in 1963

- Treaty on the Non-Proliferation of Nuclear Weapons(NPT) in 1968

- Intermediate-range Nuclear Forces(INF) in 1987

- Comprehensive Nuclear Test Ban Treaty(CTBT) in 1996

is only my daughter.
