MIRACLE GIRLS (Mirakuru Garuzu), by Nami Akimoto. First published in 1991 and first published in North America in 2000.
PLOT:
Toni and Miki are twin sisters with a secret: they can talk to one another psychically, and when together they can even teleport. This becomes handy when brainy Miki finds herself stuck on the relay race team for her school's sports day and needs sporty Toni to switch places with her. Toni finds it hard to keep up the charade when she starts falling for Miki's classmate Jackson, and harder still to avoid the attention of science teacher/wanna-be paranormal researcher Mr. Kageura.
