Second Lieutenant Mononobe Yuu has been sent to Midgard, to attend the all-girl's school where his sister Mitsuki is the student council president. The school is specifically for people who have "D" powers, who are needed to fight dragons, and both Mitsuki and Yuu fit the criteria. On his arrival, he meets and befriends another classmate named Iris Freya, who is having difficulties with her "D"-related schoolwork. They will do their best to succeed in this dangerous world.

I'm on a short Manga kick right now, so at 21 chapters this was a good size for me at the time. There's a bit to discuss so I'll get right into it.

Story: so the actual plot itself is a really neat idea. The problem is the writing and decision making on behalf of the author. There's a lot of information, and plots that are all going at once, youre left feeling a bit flustered with the amount of things you have going on. I don't mind subplots, but with only 20 chapters you need to tone it down. Though the ending is own for read more

Manga versions of long light novel series are often just disappointing advertisements for the novels. Unlimited Fafnir is a little bit better than that... but just a little bit.

Story: 5/10 There are WAY too many plot elements for 20 chapters. Three years earlier, a boy mysteriously saves his sister from a dragon. He then gets whisked off to be an assassin for the military, while she develops supernatural powers, related to the dragons, and is sent to a school to train those. This series starts with him joining her at that school--the only boy there--and encountering a pretty naked girl. read more

This is my first review so bear with me!

I thought this was a great concept and I really did want to enjoy it a lot. But I am going to have to give it a generous 5 rating. I’ll write some pros and cons:


Nice concept for a story

The lingo and terminology for the story’s sci-fi aspects were well described and easy to understand.

The art was good, and not overly fanservicey for a harem.


The story was very poorly executed. Not only that, but I had this feeling midway through the 4th and final volume that the ending was going to make it worthwhile. Instead, there was read more

Let's talk about Unlimited Fafnir shall we?

This manga is by all accounts a harem, built with some mecha-esque elements and so on so forth it's a battle action that reminds me of Darling in the Franxx yet fails to reach that peak of intrigue that Darling in the FranXX had. At least in the first couple episodes.

I think personally this manga could've prospered if given more chapters, it ends on a note that leaves so many questions unsolved and I don't think it was out of choice.

The 21 chapters that is alloted is all to introduce characters, the dragons, and deepen relationships however those read more
