Something Missing

is the forty-third episode of Kamen Rider Den-O.
==Synopsis==
With the realization that the defeat of Kai may mean the departure of the Imagin, Ryotaro begins to try and prove that he can fight on his own without any assistance.
==Plot==
After giving Owner his Gold Spoon collection, which everyone thought would answer their questions, the Stationmaster reveals he doubts that Yuto is the key to the Junction Point. In the present, Ryotaro and Kohana ponder Owner's words that something is amiss in the Yuto mystery and Ryotaro's memories may not be as true as everyone thought. However, while training Ryotaro, Momotaros senses the Armadillo Imagin as he fulfilled his contract. By the time M-Ryotaro arrives, the Imagin retreats into June 25, 2005. M-Ryotaro was about to chase after the Armadillo Imagin when Kai and the Albinoleo Imagin arrive. Kai then reveals the result of Den-O's impact is erasing all Imagin by giving Ryotaro an ominous revelation: the "day he and the Tarōs will part ways" draws near. Horrified and confused by this, Ryotaro demanded an explanation from the Tarōs, with Momotaros changing the subject with the current crisis. Ryotaro arrives to confront the Armadillo Imagin, but refuses to use the DenKamen Sword and attempt to restrain the Imagin. Zeronos Zero Form attempts to aid Ryotaro, but Ryotaro's reluctance to kill places both Riders at a disadvantage until the DenLiner saved them. However, the incident drives a wedge between a disgusted Momotaros and a vexed Ryotaro, who decides to end his contract with the Tarōs, wishing them to leave him alone. But as the Armadillo Imagin stowed on the DenLiner, Kai questions why Yuto protected Ryotaro instead of Sakurai.
