I Have The Face For It, Don't I?

is the thirty-seventh episode of Kamen Rider Den-O. It marks the debut of Kai.
==Synopsis==
Ryutaros finds himself conflicted when his boss arrives to check on his progress, while he continues to feel the anger of trying to win Airi from Yuto.
==Plot==
While training with Momotaros, Ryotaro starts to question the strange things occurring since the new line started forming, with the Imagin being evasive on the subject. On the DenLiner, Ryutaros is troubled as he receives a psychic message from the one who assigned him to kill Ryotaro, refusing to carry out the task. The very figure, Kai decides to handle things himself with the aid of the Leo Imagin and his Leo Soldiers. The next day, Ryutaros presents the gang a drawing of Airi, wanting to give it to her. But Momotaros' words annoy Ryutaros and Ryotaro takes him out before a fight starts. At the Milk Dipper, R-Ryotaro arrives as he sees Airi with Yuto, running off in a fit. R-Ryotaro attempts to dance to forget about Yuto and calm down, until Kai arrives and out does him in a dance-off. Once realizing who he is, Ryutaros assumes Den-O Gun Form, the Leo Imagin protects his master as Kai offers a new deal: A contract with Yuto so he can have Airi. Soon after, the DenLiner arrives at the Time Station, the others looking around and meeting the Stationmaster as the ZeroLiner also arrives. While the others are looking around, R-Ryotaro messes with the ZeroLiner's systems using the Rider Pass. But while Yuto chases down R-Ryotaro, the ZeroLiner connects to the DenLiner and both trains leave the station. Momotaros and the others attempt to get to their train, but the Leo Soldiers intercept them and the three Imagin are forced to fight them. Meanwhile, R-Ryotaro arrives back in the present, with the Leo Imagin revealing that Kai had no intention on completing the deal as it was to get rid of the DenLiner and Den-O's Rider Pass. Yuto arrives in time as he battles the Leo Imagin, with Kai telling Ryutaros that he has no more need for him and intends to destroy him.
