The world is thrown into chaos when the Katjvarna empire takes arms against the Republic of Kioka. Our hero, Ikta, detests war but ultimately has no choice but to become a High Grade Military Officer to defend his land. No one could have ever imagined that this lazy womanizer would eventually become the hero everyone needed.


Tenkyou no Alderamin adapts the first 3 novels of Bokuto Uno's light novel series of the same title. It also utilizes content from the 7th novel in the 5th episode.

Nejimaki Seirei Senki: Tenkyou no Alderamin is a 13 episode anime series based off a currently publishing novel series. Odds are, you already have realized a couple things, but if not here they are now: First, this series tidies up an arc at the end, but it otherwise has an open ending. Second, odds are there won't be a second season; if lucky, there will be an OVA in the future, but it likely won't even be that. So, if these two factors are a big deal, you may want to wait on watching the series. If you don't mind, continue reading for a more read more

Alderamin on the Sky isn't an overly impressive anime by all means, but it is enjoyable for what it is. It is a military, strategy themed anime which focuses on the cruel reality of war, politics, and how our MC, Ikta Solork, makes his legend by displaying his superb talents as a strategist.

The plot isn't original, but that isn't always a bad thing. Alderamin is mainly focused on the war between two neighboring empires Katjvarna and the Republic of Kioka, and the struggles of Ikta and his comrades fighting in the war. Besides the ongoing warfare between the two countries, there are also tension read more

"Great soldiers die from overworking" - Ikta Solork

This anime was actually quite the surprise where it was presented at first as a typical battle harem anime, but instead brought us an anime about tactical warfare and two rather unique main characters.

The plot of Nejimaki Seirei Senki: Tenkyou no Alderamin is more focused on it's war themes as well as their religious elements that enforces the war themes and puts them in conjunction with it's interesting characters.

Nejimaki Seirei Senki: Tenkyou no Alderamin's chaarcter like Ikta Solork voiced by Nobuhiko Okamoto and Yatorishino Igsem voiced by Risa Taneda are some very interesting characters, Ikta is forced to read more

War is not without causalities. Or a purpose. Or strategies. I must admit, watching Nejimaki Seirei Senki: Tenkyou no Alderamin (Aldermain on the Sky) reminds me of many war movies I’ve seen although it’s also quite different than what I had anticipated. Maybe it’s the military gimmicks or the character relationships. But for what’s worth, Alderamin may surprise you in more places than one.

Adapted from the light novel, I was slightly disappointed that the show is only 1-cour. After all, there is more than enough content for a 2-cour length series so when I heard the show would only feature 13 episodes, my hyped died read more
