Nozomu is paying a visit to Chiri's house after going through various scenes, but his home visit abruptly ends when he reaches Chiri's house.

Meanwhile Nozomu points that many Japanese put efforts into various activities despite being aware there won't be any reward for their action. A number of Nozomu's students ends up doing improper conducts as they don't expect themselves to appear in front of the audience. In the third part of the episode, the students are worrying about the dropping interest of book-reading among students. Nozomu thinks that many books should change their titles so that they accurately reflect the content of the book as many books betray the readers' trusts by having inaccurate title. Thus, Nozomu asks Kino and Kudo to give more appropriate names for various books by holding a book-titling competition. Air Date : 10th-Dec-2008
