Takayuki appears in Foreign Exchange he is a Japanese exhange student and doesn't settle well in the Heck House.

He didn't seem to have fun while in Orson, Indiana. The Heck's tried hard to get him to open up, while everyone else was having a great time with there exchange students. This made Frankie mad and jealous. When Frankie has Takayuki go on a road trip to Brown County for fun, the car ends up breaking down, but Takayuki says he can fix the car and does, he later fixes some other things around the house, such as the toaster and the TV. At his home in Japan, it is shown that he acts like both Axl and Brick.
