Love Hina Again EP1 - Kanako

After deciding to take the semester off from Tokyo U, Keitaro goes to America with Seta to explore different archaeology sites. Kanako, Keitaro's step sister, comes to the Hinata apartments and appoints herself as the new landlord in Keitaro's absence, much to the annoyance of all the residents. Kanako makes many new rules, one which the residents try to break in order to find her weakness. What they didn't know was that it had to do with a certain promise Keitaro made with his "little sister." Although, Naru remembering her sister tries to help and defend Kanako, not knowing she plans to drive her out. At the end of the episode, Keitaro returns.
