Taro is the cousin of Tenchi, he first appeared in the episode 08 of the OVA series, "Hello Baby!". He looks a lot like Tenchi (though Ryoko claims he - Tenchi - was even cuter as a baby). Tenchi's aunt "requested" that Tenchi and rest look after Taro for several days while she took care of Taro's sick mother. He was a handful for Ryoko, Ayeka and Mihoshi, although Washu (who had a baby before) had little to no trouble with him. He returns in the second episode of OVA 4, and is still a handful for everyone.
