This was fun to watch!

I was shocked to hear that she was 167 cm (approximately 5 feet 5.7 inches) when she graduated from elementary school (assuming the YouTube captions were accurate). A bit hilarious when a couple of the hosts joked about "Shingeki no Kyojin". It also made me realize that Kaori must have had a complex about her height as a kid and especially in her teen years. She was probably bullied at some point.
She only grew about 4 inches further until she became an adult, so she just had a massive growth spurt as a young girl. I can relate to that having had a growth spurt as a young teen but not growing much after that.
She played golf in high school, imagine that. She played mahjong at home through her dad.
She's a very lovely and has a great figure and stance. She's not a classic diva but more of a pop/soft rock girl (looking up to groups like SPEED when she was young).
