At the end of Episode 21, Agent Cures Secret, Undercover, and Thunder are battling the monster that Ateb made. But since the monster was too strong, the 3 Agent Cures can't defeat it. But suddenly, 2 mysterious Cures fought the monster in seconds and it was purified. Agent Cure Secret told the fighters, who are they. They didn't answer and they escaped.
Reunion in The Headquarters
At the beginning of episode 21, Kotaku and friends were spying on the 2 mysterious fighters, their sure that they are in the headquarters since all spies train there. Luckily, they saw them. They were doing something, at least, mathematics? Rei knows what they were doing, they were doing algebra, quickly. Kotaku suddenly calls them from the open door "Hey, Genius!". Akari and Rei froze and stood still, and the 2 fighters looked back. Kotaku said that they are geniuses, and Alpha kicks the 3 spies out of their room.
Joining The Team
When the 3 villains showed up in Undercover Bright City again, The Spy Pretty Cures transformed and Alpha and Natsumi saw them. They knew that they spied on them because they think that Natsumi and Alpha are Pretty Cures, and yes, they are the rumored Agent Cures Buster and Mission. They both are the strongest Agents in Undercover Bright City. Natsumi and Alpha decides to transform and they performed their attacks. Then they decided to join the Spy Pretty Cures.
Alpha was created by her genius master, Natsumi. She calls her robot 'Alpha' which means 'the best' (See Etymology) because she wants Alpha to be the best robot ever.
Alpha is a Math and Science genius. But sometimes she can be a 'wild robot'. Alpha cares for her master, and she sometimes teaches the kindergarten children in the Headquarters. She is known by the nickname "Alpha-Bot" by the kids because she teach the letters in the 'Alpha'bet to the younger kids. Alpha is good friends with Kotaku's robot, Beta. And Alpha never knew that Beta has a crush on her.
