It is no secret that anime is often created to help sell manga, light novels, or just merch in general. It is like a 12-episode promotional commercial to help get you hooked on characters and invested in the plot. It is why you see so many anime series that only adapt fractions of the source material, never to be heard of again. Either it wasn’t received well or it didn’t boost sales enough.
But not always!
Creativity is dying, but never dead. Sometimes anime studios dare to make an original creation that has no light novel or manga to dictate its story. However, these original anime series always end up in a very Schrodinger’s Box place when it comes to their conclusion.
As they are original stories with no source material, they are both finished and unfinished. A series could end with a cliffhanger and never be picked up again, and that is how the story was meant to end because there is no source material saying otherwise.
Then you have series like, for example, Psycho-Pass. The series could have and perhaps should have ended with its very strong first season that told an interesting story to a satisfying conclusion. Yet, they made two more seasons and a series of movies in that world, because it is technically an open-ended detective story – there is always another case and another cop to solve it.
If you are looking for “complete” original anime with no source material, I’ve gathered a list. I went through 4,500+ entries in the MyAnimeList database (I saw Ex-Arm and where the ratings end o_o), clicking on everything reasonably well-known enough and that I didn’t already know had source material.
I can say that, from what have seen on this list – which is a decent portion, but not all – these stories end pretty conclusively, but again, original anime stories with no source material can end in an open-ended way just in case the studio thinks they might be able to pick it up later.
As a note, any series that do have manga or light novels – as many of the below do – had those written based on the anime, not the other way around.
Complete Original Anime With No Source Material
***** 2/20/2026 ***** The “Does It Have Manga/Novel Adaption?” column is a new addition, and is presently a Work in Progress. Please be patient as I fill in the contents as I have spare moments of time. Latest Update: April 24th.
| Series | Does It Have Manga/Novel Adaptions? |
| 5 Centimeters Per Second | Novel and manga both expand upon the story with new inner monologue, character focus, and—in the manga’s case—additional context for the ending. The One More Side novels examine the story from different perspectives. |
| 91 Days | Adapted to 2 Novels, does include new content in its three novel-original chapters and an additional epilogue for the story. |
| AICO: Incarnation | Three-volume manga adapts the anime. |
| Akiba Maid War (Akiba Meido Sensou) | Has a 6-chapter 4-koma manga that is just jokes. |
| Akudama Drive | Nine-volume manga adapts the anime story, but does offer a lot more details on the various characters and their individual stories. |
| Aldnoah Zero | Manga series labeled Season One and Season Two cover the anime. Twin Gemini is a manga-original side story. Season Two manga does lightly expand upon the ending. |
| A Lull in the Sea (Nagi no Asu kara) | 6-volume manga adapts the anime story. |
| Angel Beats | Last Operation manga adapts the anime but wedges in a lot of extra content for the characters. Track Zero light novel is a single-novel sequel about the founding of the SSS. Heaven’s Door manga is a manga adaptation of Track Zero. There is also a visual novel adaptation that adapts the anime, but has romance routes. |
| Anila to Cocora | No manga or novel adaption. |
| Animegataris | No manga or novel adaption. |
| AnoHana – The Flower We Saw That Day (Ano Hi Mita Hana no Namae wo Bokutachi wa Mada Shiranai.) | Novel, Manga, and Visual Novel all adapt the anime with minimal new content. |
| A Place Further Than The Universe (Sora yori mo Tooi Basho) | Three-volume manga adapts the anime with small added moments between the characters. |
| Apocalypse Hotel | Single volume manga is just comedic skits. |
| Appare-Ranman | Three-volume manga adapts the anime. |
| Aquarion | Genesis and Evol both have manga and novel adaptations, but they only cover the anime story. Future Legend is a one-volume Genesis side story. |
| Argento Soma | No novel or manga adaption. |
| Astro Note | No manga or novel adaption. |
| Ayaka | The ongoing Muzzle Flash Back manga is adapting the anime, but includes a lot of new content and context right from the beginning. |
| Bakuten | Two-volume manga adapts the anime. |
| Bang Brave Bang Bravern | No novel or manga adaption. |
| Basquash | Two-volume manga adapts the anime. Eclipse Stage is a spin-off following the Eclipse Girls. |
| BBK/BRNK | No novel or manga adaption. |
| Blassreiter | Genetic manga is a side story following Snow. Judgement is a light novel I can’t find. No proper novel or manga adaption. |
| Blood+ | Both the manga and novel adaptation work with the same story, but greatly change and abridge a number of parts of it. The Russian Rose novels and Adagio manga are both prequel stories about Saya and Hagi in the Russian Revolution. Kowloon Nights manga is a prequel about Hagi looking for Saya and getting worked over by sinister men in a Boy’s Love story. |
| Blue Gender | Single volume manga is an extremely abridged adaption of the anime with a “similar, but different” ending that ends up in the same place anyway. |
| BNA – Brand New Animal | BNA Zero: The Animals That Can’t Be Brand New novel is a prequel about Shiro. The single volume manga tells stories set in between events of various episodes of the anime, so it is more of a companion than a continuation. |
| Bucchigiri!? | No novel or manga adaption. |
| Bucchigire Bakumatsu Bad Boys | No novel or manga adaption. |
| Buddy Complex | Two-volume manga adapts the anime. Coupling of Battlefield is a manga adaptation of the mobile game story. |

| Bullet / Bullet | No novel or manga adaption. |
| C-Control : The Money of Soul and Possibility | No novel or manga adaption. |
| Candy Boy | The two-volume manga is more positive about the relationship, introduces more characters into the story, and can be a bit different from the anime outside the core moments. Young Girls Fall in Love manga is a spin-off following Sakuya. |
| Cardfight! Vanguard | … We’ll tackle this in a post all it’s own, because it will be lengthy. Coming soon™ |
| Carole & Tuesday | Three-volume manga adapts the first half of the story, with a manga-original conclusion. It also focuses less on the plot and more on the relationship between the two girls. |
| Case File nº221: Kabukicho | No novel or manga adaption. |
| Casshern Sins | Has a single-volume manga adaptation, but I can’t find it. |

| Classic Stars | No novel or manga adaption. |
| Classicaloid | No novel or manga adaption. |
| Classroom Crisis | Two-Volume manga and Three-novel light novel series adapt the anime. The manga is very similar to the anime, the light novels do expand on the anime story a bit more, even going beyond the anime end. The Two-novel Another Crisis novels are just side story slice of life fluff. |

| Concrete Revolutio | The Two-volume manga re-arranges the non-linear events from both seasons into a stream-lined, more condensed story, but does have a different, manga-original ending. |
| Cosmic Princess Kaguya | The novel adapts the movie story and, while the manga also adapts the same story, it tones down the yuri as the manga artist is homophobic. |

I don’t know if you go back and update stuff in situations like this, but Link Click has been confirmed to get a third season, so it’s not actually complete.
Love Through a Prism
Added! Thank you for taking the time to let me know.
