First...this isn't the omnipotent Tenchi that can use LHWs....we are talking about the regular Tenchi from the TV series that only can use Tenchi-ken. He learned juraian swordmanship from Yosho and he showed his skill twice in the series. First when he rescued the girls from the Galaxy Police and then when he fought against the guards in the standpoint. Can THIS Tenchi wins against Ranma?. Think about this Tenchi as a more skilled version of Kuno Tatewaki with a light saber.
