Circumstances, Farewell, and a Tearful Birth (事情と別れと涙のバース Jijō to Wakare to Namida no Bāsu) is the thirty-eighth episode of Kamen Rider OOO.
Eiji tries to deal with Akira as he joins with Maki and the Greeed while Shintaro tries to figure some way of winning Birth back to their side.
Joining Doctor Maki to get the hundred million, Akira becomes Kamen Rider Birth to support the Greeed by keeping Shintaro from interfering before attacking Kamen Rider OOO Takauba with Mezool and Gamel while Kazari goes after Ankh. Coming to, Shintaro uses the Candroids to cover Eiji and Ankh's escape. At the Cous Coussier, the group talk about how Akira's betrayal must be related to the ¥100 million he is trying to raise. Shintaro tries to get a loan from Kougami, but the man refuses and tells him he must let his desire grow. Later that night, at Doctor Maki's manor, Akira goes into a debate with the doctor about his intentions to end the world before learning he is to accompany him to get the remaining Core Medals. The next day, arriving at Maki's location after sensing the purple Medals in him, Akira is about to fight Eiji when Shintaro arrives and asks him if he is willing to do this if for his dream of building a medical school. But Akira reveals that the money is actually for his surgery much to Shintaro's shock as he prepares to fight Akira himself to save him as he and Kamen Rider Birth ready for a shooter's duel. However, it turns out that Akira was actually working for Kougami the entire time to stop Doctor Maki from becoming a Greeed. Despite learning that the self-destruct mechanism he placed in the Kamen Rider Birth suit was removed by Shintaro, Doctor Maki has the Greeed emerge from their hiding places to consume Kamen Rider Birth in a massive explosion. As Eiji becomes Kamen Rider OOO Sagohzo Combo to fight the Greeed, Shintaro tends to a mortally wounded Akira who tells the young man to believe in himself before seemingly succumbing to his injuries. With a new resolve, Shintaro arrives with the Birth Driver in hand just as Kamen Rider OOO is defeated. Shintaro transforms into Kamen Rider Birth, activating the Birth Day armor to hit the Greeed with a massive Cell Burst attack. Luckily, Ankh (Lost) arrives and spirits the Greeed and Doctor Maki away. Later, after it is revealed that he faked his death to give Shintaro the drive needed to replace him, Akira receives ¥50 million from Kougami for his services, reaching his intended goal thanks to the ¥50 million he got from Doctor Maki's bribe. As Akira bids Eiji goodbye before entering his plane, telling him to remember his desire, Shintaro trains under the confidence that they will meet again.
