Kenshi—half-brother of intergalactic hero Tenchi Masaki—has been summoned to the mysterious world of Geminar, and his only hope of returning to Earth is piloting a bio-mechanical weapon in a shocking assassination attempt! When the mission fails and Kenshi is captured, he discovers he's been lied to by the very culprits who transported him to this strange new world. Luckily, Princess Lashara kindly welcomes Kenshi and invites him to live amongst her followers. Now, caught up in a political whirlwind—and hotly pursued by Geminar's female population—Kenshi must find a way to get home while civil war erupts all around him!

Isekai no Seikishi Monogatari was my first time watching an OVA series that comes out every month rather than every week. As such, I was not prepared for the gnawing impatience I felt at the end of every episode.

At first I wasn't really absorbed with this series and just started watching it while waiting for one of my downloads to finish. However as the1st episode progressed, I slowly found myself getting drawn into the story. The basic storyline wasn't anything new. It had the same premises as some other fantasy series with the main character getting thrown into an unknown world in order to read more

As a fan of Tenchi Muyo and its franchise, Isekai no Seikishi Monogatari, would have to be if not the best spin-off that's come out to date. Bear in mind, my review will be very biased due to nostalgia playing a big part(having grown up to Tenchi anime instead of Pokemon or Dragonball)

Whilst there are subtle references to the MC being part of the Tenchi Muyo universe(TenchiVerse), I doubt it would be enough for anyone to think that they would need to watch the past franchise before starting this series.

Story: 6
The story itself is pretty generic and is about a boy who is summoned to read more

I have watched the entire season of this 4 times and have not found myself bored once.

The overall story line of this anime starts a bit stereotypical, but the development is excellent.
Not to mention that the main character is an overall bad ass with a kind, although a little too innocent, heart.

Although sometimes a little cliche, this anime is found very enjoyable and one is left with other regret there is not more of it!

As a personal bit: WAHANLY IS THE BEST! :P

Seeing as how this was actually a forum post of mine when I went on a rant after watching this dreadful series, I wanted to bring this out to the front page and see what you're truly getting yourself into.

This does contain some spoilers, but it will not impact the series in any way. Anyone who has not watched this should not have a problem with the spoilers as it does not reveal any plot twists, etc(except episode 1, but what the hell, it's episode one haha).

The graphics and battles were top notch. However, the entire series was literally a land fill of fillers read more

Mecha, hero, and hot girls. The only difference is that Isekai has a better plot, twists, and girls are hotter.

Anime: Break Blade 1: Kakusei no Toki
both have guys with incredible talent using some sort of machine that runs on power provided by the user to help save their country from being taken over.

Anime: Neon Genesis Evangelion
If you liked Isekai, see where its creator Kajishima Masaki got his mecha ideas from. Although the stories are totally different, the similarities in mecha design down to how they are powered and controlled are clearly exact(even to how the mecha's for the main leads roar)...
