Venus to Mamoru! - Season 1 Episode 18 In the Middle of the Storm

The episode starts out with the flashback of when the man that could use beatrice, Ayako-san, and Mamoru-kun (Ayako-san and Mamoru-kun are kids). While they are stuck in the cave the man from the flashback goes and finds Student Council President and Vice-President. The Student Council follows him to where Ayako-san and Mamoru-kun are. The man tells them that they have to destroy these things called prisms because it eliminates the ability to use beatrice. As the Student Council members start destroying the prisms the beatrice slowly comes back. When Emelenzia-san destroys the prism that is in the flowing river, Mamoru-kun and Ayako-san are able to due away with the storm and clear out the rocks. Mamoru-kun discovers that the man from the flashbacks is none other than Misaki-san. After Ayako-san and Mamoru-kun get to Rainbow Cliff they share their memories that have come to lead up to an everlasting love and they also share a kiss. After that we see Misaki-san on the phone getting ready to get on the plane when we find out that he was talking to Johan-san.
