Somehow, Anthy's curry and rice explodes and that shock switches Utena and Anthy's personalities. Now Utena is feminine while Anthy is tomboyish. The cause of the incident seems to be Nanami's practical joke, trying to mix in the curry the "100X Curry, an Indian Specialty Hot Enough to Make You Breathe Fire". which has mistakenly been replaced with the "Super Spicy 900 Billion X Curry, So Hot It Will Blast You to Smithereens and Make Phantom Elephants Trumpet Loudly". Scolded by her brother, Nanami flies to India to obtain more of the same spice.
