UFO Baby (だぁ!だぁ!だぁ!, Dā! Dā! Dā!?) is a shōjo comedy manga by Mika Kawamura, serialized by Kodansha in Nakayoshi between February 1998 and March 2002, and collected in nine bound volumes. The series was adapted as a 78-episode anime television series, produced by NHK and animated by J.C.Staff, broadcast between March 2000 and February 2002 on NHK's BS2 broadcast satellite network. The series was one of the top-rated anime series during its initial broadcast.
UFO Baby is about two junior high school students, Miyu and Kanata, who find and must take care of an abandoned alien baby without anyone discovering they are living together. The anime concluded before the manga did, resulting in different endings for each series. Kawamura later wrote a sequel to the manga, Shin Daa! Daa! Daa!.
