Beibei Yang is a supporting character who appears in the anime series Anime-Gataris. She is a Chinese exchange student originally from Beijing, China. Her immersion in anime fandom is a central aspect of her identity, and her love for the medium is so strong that she travels to Japan specifically to attend anime-related events. She initially began watching anime as a way to study the Japanese language, but this academic starting point quickly blossomed into a genuine and deep passion.

Beibei is depicted as a young female teenager with blue eyes and black hair that reaches chest-length. Her role in the story begins when the main characters' anime club encounters her at Comiket, a large convention for fan-made works. At this meeting, she shares her perspective that anime is also very popular in China, broadening the series' view of fandom as an international community.

In terms of key relationships, Beibei meets Minoa Asagaya for the first time at the Otacon event, and the two quickly bond over their shared and enthusiastic love for anime. She also attends the same school as Maya Asagaya, which further integrates her into the circle of main characters. Her primary motivation throughout her appearance is her genuine, self-driven passion for anime, which is what leads her to travel abroad and connect with fellow fans. She stands out within the series as the only foreign otaku among the main cast. No significant information is available regarding a character arc or notable abilities beyond her deep knowledge and enthusiasm for anime fandom.
