As Tajikara and the others were concerned about 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.
