嘆きのナイト

ガイを追いつめながら、とどめを刺せないナイト。そんな蓮を、淳はリタイヤとみなし、手塚は破滅とみなした。一方、懇願する優衣に負け、清明院大学の仲村から神崎士郎の関係資料がもたらされる。また、諸々の悪事が露見した淳は、警察に逮捕されてしまう。

With Ren doubting his ability to go through killing other Kamen Riders, Shinji and Miyuki contemplate his possible paths and the potential doom that he faces. As Sanako decided to go out for her 'secret association meeting', Yui continues to investigate the truth behind the secret experiments her brother conducted. Meanwhile, Shuichi attempts to release a prisoner.
