Rosa

Rosa (Chichos in the Japanese Version, Guadalupe in the Latinamerican Spanish Version) is a young Mexican DigiDestined, partnered to a Gotsumon. Rather immature and egocentric, she quickly becomes attached to Ken Ichijouji and takes a dislike to his Digimon partner, Wormmon.

Digimon Adventure 02
Prior to Ken Ichijouji and Matt Ishida's arrival in Mexico, Rosa and Gotsumon had snuck out of their house and entered a Mayan Temple with the intention of waiting for the two of them to arrive to assist her. Rosa and Gotsumon met Matt, Ken and their partners inside the Mayan Temple and she tells them that she snuck out. In the original version, she doesn't speak Japanese and only Ken can understand her since he understands and knows how to speak Spanish. Her crush on Ken made Wormmon jealous and sparked a little animosity between them. She called him a worm in Spanish and Matt tells Ken not to tell Wormmon that.

When Jose (Gennai's Mexican counterpart) leads them to the Digimon in the Temple, Ken says that the Temple must not be destroyed and Matt provokes the Digimon into chasing him so that he could lead them out of the Temple. As they make their way out of the Temple, Rosa falls down and Ken carries her on his back. Once the rogue Digimon were out of the Temple, their partner Digimon fought and subdued them. Rosa, who is still being carried by Ken on his back, falls asleep and mutters in her sleep about Wormmon. Wormmon thinks she is still insulting him but Ken tells him that she said "Wormmon is amazing".

She is returned home to her worried parents who are relieved to have her back. As she sleeps in her bed, she dreams about Ken and Wormmon while her parents watch over her from her door of her bedroom while Gotsumon sleeps on the other side of Rosa's bed, away from the view of Rosa's parents with a part of Rosa's blanket covering the top of his head.

In the final battle against Malomyostimon, Rosa is seen at the Mayan Ruins again. She holds out her Digivice which sends out a beam of golden light to sky after she calls out Gotsumon. Shortly after, the unnamed and unseen Mexican Chosen Children send out the light of their Digivices. They and Rosa are the last among the International Digidestined to do so. She stands with Matt and the Russian Chosen Children when she lands in the Digital World.

Rosa is one of the only two International Chosen Children to have had their parents featured. The other Child is Michael. Rosa is also one of the youngest Chosen Children in the series.
