SO I SHOWED MY MOTHER PICTURES OF TOKIO. This took a lot of trust on my part, since our last experience with jpop was a picture of Shuuji to Akira, and I asked her who she thought was hotter. She pointed to Kame. I didn't scream and wash her eyes with soap, but it was very hard.
Anyway, I showed her TOKIO, and she tolerated Taichi, enjoyed Nagase ("pretty damn fine!"), appreciated Gussan shirtless, and made some noises at Mabo I seriously didn't need to hear.
Then I showed her a picture of Leader.
Her immediate, unprompted reaction was "Augh."
When I asked who was her favorite, she added -- COMPLETELY FREE OF MY INFLUENCE -- "Anyone but that last one."
...
This proves it, I think. It's not just Leader's presence. It's -- it's in his blood. XD
