Rika's family and friends were planning a party for her and she was less than enthusiastic when Takato spilled the beans to her, after suggesting they go cherry blossom watching together when they actually happened "later" as Rika describes. The appearance of Locomon called her into action, along with Renamon, jumping onto one of Locomon's carriages with Takato. Taken over by a Parasimon which tricked her into attacking Takato and Renamon with memories of her father, Rika was freed when Guilmon destroyed the Parasimon controlling her. She Bio-Merged with Renamon to Sakuyamon to help defeat the Parasimon invasion in Tokyo. Following their defeat, Rika attended her birthday party thrown by her friends, only to leave just after blowing the candles out and being asked to sing karaoke.
