This was the 92nd video by Maeshima Ami for her youtube channel. This video was around 10 minutes.

In this video Ami tried to do tongue twisters. Ami was a seiyuu, but she wasn't that good at doing tongue twisters. She tried to say 100 in 10 minutes.

Ami had lots of trouble and she slowed down a little, but she was able to do 60.
