Yokohama Disturbance II is the twentieth episode of the Mahouka Koukou no Rettousei anime.
Tatsuya talks with Mayumi about the Thesis Competition. When she inquired why he hasn't made a move on her in the private spot room they were in, he said that there were cameras and if there weren't any, if she offered herself, he would certainly take her up on her offer. This makes her jump against the wall in embarrassment.
Someone tries to hack into Tatsuya's computer, most likely to steal his contributions to the Thesis Competition.
