Tenchi Muyo! War on Geminar (2009) OVA Series
異世界の聖機師物語 (Isekai no Seikishi Monogatari)


Kenshi Masaki is a 15-year-old boy that has unwillingly traveled from his home on Earth to the alternate world of Geminar (ジェミナー Jeminā). On Geminar, the countries wage wars using Sacred Mechanoids, humanoid exoskeletal weapons that were originally discovered within ancient ruins and developed over centuries. After being tricked by a mysterious organization into participating in an attempt to assassinate Lashara Earth XXVIII, the young ruler of the Shtrayu Empire, he ends up captured after he chooses not to kill her. Deducing enough about Kenshi to interest her and because his abilities make him an extremely valuable property, Lashara decides to take Kenshi under her protection.

Disguised as her attendant, Kenshi travels with her and her bodyguard Chiaia Flann to the Holy Land, a virtually impregnable fortress that serves as an academy to train Sacred Mechanoid pilots, most of whom are female. With his kindness, tenacity, and skills that vary from carpentry and cooking to advanced survival techniques, Kenshi eventually becomes a celebrity in the academy, becoming the object of affection of many female students and making some of the male students envious. However, the same organization who deceived Kenshi is secretly working inside and against the academy, and a worldwide conflict is about to begin.

TL;DR Review

Tenchi Muyo! War on Geminar is supposed to be to be related to Tenchi Muyo. It tells the adventure of Tenchi younger brother as he was transported to a new world. It may as well be a completely new anime, for there was practically no reference to the Tenchi series. This feels like a ploy to name drop the brand Tenchi Muyo onto this obscure anime.

I hate to admit it, but I watched all 13 OVA back when it initially released. I can’t tell you what the story was about because it was so generic and forgettable. Trying to re-watch it now, I’ve lost track of how many time I’ve rolled my eyes watching the first episode.

The art is decent when it comes to drawing the main characters, but anyone that isn’t important may as well be a blob. The mecha design is generic, you can’t tell one from another other than from their color. Oh, it’s a white mech vs a red mech.

The opening theme “Follow Me” by Seira Kagami feat. Sound Around and the closing theme “Destino” (Italian for “Destiny”) by Alchemy+ are quite good. Unfortunately, they are the only good things from this anime.

War on Geminar is like a poor man version of The Vision of Escaflowne, but with a harem, and no story. The bad guys will constantly yell and flaunt their attack like some grade school bully. Women throw themselves at Kenshi for no reason. None of the characters are likable or relatable, as they don’t act like real people.

I would not recommend this anime to anyone. I think this anime demographic is for children but are old enough to fantasize about a harem I suppose? Tenchi Muyo! War on Geminar contains crude humor, moderate suggestive themes/dialogues, and nudity. Intended for young adults.

A Certain Magical Index Season 2 Review

On a transfer from England to Japan the “The Book of the Law” has been stolen. This is all the more disturbing since deciphering this book supposedly spells the end of the Roman Catholic Church, and thus destroys the equilibrium of power in the world. To make matters worse the nun, Orsola Aquinas, who recently discovered a way to decipher the book, has been kidnapped…

At the Academy City the Daihaseisai, a sports festival, is underway. This “opportunity” is used to trade the Stab Sword — a spiritual weapon capable of killing Saints with one blow. But as it turns out the actual sword in question is far more dangerous…

Black Clover Season 1 Review

Asta and Yuno are orphans who were raised together from birth after being abandoned at a church orphanage on the outskirts of the Clover Kingdom at the same time. In a world where everyone has the natural ability to perform a kind of magic, or a Magical Power (魔力 Maryoku), Asta is the only person born without any, leading him to train physically as compensation. Conversely, Yuno was born as a prodigy with immense magical power and the talent to control it. When they are 15, Asta and Yuno are granted the ability to become wizards known as Magic Knights by receiving grimoires, with which all magical power is channeled. Yuno is granted a wind-based grimoire held by the kingdom’s first Wizard King, while Asta does not receive one. However, when a thief incapacitates Yuno to try and sell his grimoire on the black market, Asta summons his own grimoire, which contains the rare and mysterious Anti-Magic (enabling him to cancel out all magical effects), to defeat him. The story then follows the two boys in their time within separate squads in the Magic Knights, as they build a friendly rivalry to try and become the Wizard King themselves.
