Episode Title:
Some Fascinating Humans.
Episode Description:
The next morning, Himeko, Yoshifumi, and Yui all switch bodies together, though soon revert to normal. After the gang are excused from absence in class, Taichi briefly ends up switching places with Yui before getting grilled by Iori over what happened the previous day while he was in her body. Just then, the gang is approached by someone who had swapped bodies with their homeroom teacher Ryūzen Gotō, calling himself Heartseed, who is revealed to be responsible for the body swapping, vaguely explaining the situation before leaving. A week later, the group discuss how best to handle the situation without making anyone else suspicious. As Iori later swaps bodies with Yoshifumi, she talks with Taichi about how the switching may affect their individuality before she switches back. The next day, as Taichi and Himeko switch and end up volunteering for off-campus cleaning duty with Maiko, Himeko decides to get revenge against Taichi and declare to Maiko that Iori is hers while in Taichi's body.
