Tajikara along with his wife and fellow tribe members were on their way being taken to Tokoyomi Shrine until the village's elder became too exhausted to walk anymore and fell. As Tajikara and the other were concerned for the elder's condition, the Dark Tribe had little care for the elder and instead beated him. Tajikara and the others defended the elder, however the Dark Tribe's superior Tsuchidama did not tolerate weak slaves and ordered his minions to kill the prisoners. Doraemon, later known by the Hikari Tribe as Dorazombie, and the others were able to fend off the Dark Tribe and destroy Tsuchidama. Tajikara and Tarane were later reunited with their son.
