天地无用！魉皇鬼
柾木神社的继承人柾木天地，是非常普通，随处可见的青年。天地期待的弟弟诞生了，他的名字叫做“柾木剑士”。虽然是命中注定要单独前往异世界的少年，但他毫不畏惧命运，在周围的人们守护下健康地成长。然而这只是将天地、剑士和柾木家，还有住在地球上的正木一族及树雷，甚至与宇宙有关的人们全都牵扯仅来的壮大序章罢了。
Though the destiny-laden life brings a lot of joy to Kenshi's mother, Rea, and Tenchi, the days are also tinged with worries. Next to the soundly sleeping Kenshi, Tennyo and Rea discuss Kiyone and other family matters until the day breaks. Then it's back to the usual "day in the Masaki family" again. Young Kenshi is not weighed down by any of the gloomy worries the adults have and grows stronger every day. Meanwhile, the adults on the side of the Yamada family are also starting to begin talking about the things to come...
Kiriko discusses making Earth a permanent home for Seina and his family with her group. Meanwhile, Lady Seto dispatches Kuis to charge Seina with overseeing a proxy war on tabletop island. Tenchi and the group arrive on the island and are greeted by Seina.
Sparks erupt, multiple balls of fire illuminate the emptiness of space, and amidst all that, there is "Tabletop Island". Due to the plan Kuisu devised, Tenchi and Shou end up having to deal with the pirates. Even though he was still not used to being in space, Tenchi works with Shou and the others to contain and ship off the pirates, despite having his doubts. One day, "Miron Pham" and "Fuku" visit the Masaki family. Miron explains that the plan is to anchor Tabletop Island on earth. She further explains that with the "Paradise War" being concluded and the island having become a floating paradise, the conditions are finally met to invite the Masaki Family there. This would be an ideal place to train Kenshi. Both Tenchi and Washu are taken aback by Miron's casual words. With all sorts of thoughts on his mind, Tenchi accompanies Kenshi, Ryouko, Ayeka, and the others to Tabletop Island. There, Tenchi will be doing some soul searching...
While Tenchi and Seina thwart another attack on the island, Kenshi continues his training.
A few years after the previous episode, Kenshi continues his training against Minaho, Funaho, Misaki and Seto among them. That evening, a large gathering from the Juraian royal family, other royals, the Kuramitsu family and Seina's family meet with Tenchi and the girls to hear Tenchi's decision.
Kenshi’s training continues. He’s now able to defeat the girls on Banjo Island, but still cannot do it quick enough. He’s still no where near good enough to hold his own on Geminar. As such, Seina’s harem takes over the training to get Kenshi to the next level. Further, Tenchi’s harem also joins in the training, including a pregnant Ryoko.
