He is the main antagonist for the first half of the season, sending his servants after the Cures.

About halfway trough the series, all his servants are defeated and he decides to take action for the first time by visiting Sangoshō and looking for the Cures. It turns out he does not know who the Cures are or how they look like, which is why he doesn't recognize them when he runs into them. The girls try to befriend him, which results in him "transferring" to Sangoshō Middle School and living in Siren's house under the name Shinkai Robin. He also developes a crush on Sairen.

He ends up finding about their identities at the school's cultural festival but decides not to tell them. He isn't sure if he wants to fight anymore, mostly because of his crush.
