2x2The Thing That Surfaces in the Darkness / Welcome To The Yuu Episode Summary Aired: Tuesday October 12, 2010
Lala creates a mess of her own gadgets at school. As Rito tries to keep Haruna away from Lala's gadgets, Rito and Haruna accidentally activate the warp ring, sending both of them into an unknown location naked. Haruna and Rito explain about their background, but gets discovered by Mikado-sensei as the unknown location was in her clinic.
Haruko, Mikan's teacher, wants to visit Saibai (Mikan and Rito's dad) because she is a fan of his manga. Due to a new deadline, Saibai is unable to visit. Lala dresses Rito up to be Saibai, but Rito is too nervous, acting strangely in front of Haruko.
Lala invites Haruna and Yami to a sleepover party. After a big dinner, Rito decides to take a bath. However, Lala does not know about Rito's presence and invites all the girls to the enlarged bathroom she created (Rito is still inside). Although the enlarged bathroom is large enough for Rito to hide and escape from the girls, Peke activates Lala's controller, restoring the bathroom to its original size and putting Rito in front of all the girls all naked.
