07th Expansion Wiki

Ryukishi07 (竜騎士07(リュウキシゼロナナ) Ryuukishi Zero-Nana, lit. Dragon Knight Zero Seven) (birth name unknown) is a Japanese author and artist who is well-known as the creator of the When They Cry sound novel series, consisting of Higurashi When They Cry, Umineko When They Cry, and Ciconia When They Cry. He is the representative member of the group 07th Expansion.


Ryukishi was originally born in Chiba Prefecture.[2] As an adult he worked as a civil servant until he was 30.[4] During his time as a civil servant, Ryukishi developed a hobby in doujin circles and was part of a group to produce a work called Flowers, but it never released since the circle disbanded. Ryukishi later formed his own doujin group called 07th Expansion with his two younger brothers[5] and created cards for the card game Leaf Fight.[6]

Inspired by the visual novel Tsukihime created by TYPE-MOON, Ryukishi and his brothers decided to make their own novel game. Ryukishi had previously written various stage play scripts and took one called Hinamizawa Bus Stop and reworked it into Higurashi When They Cry.[7] Higurashi has since become a pop culture phenomenon, and 07th Expansion's members grew as Ryukishi became involved in many more visual novel works.

"Ryukishi07" is a pen name, inspired by the character Reina of Final Fantasy V: "07" in Japanese can be pronounced as "reinana", and "Ryukishi" means "dragon knight", referring to the dragoon job in Final Fantasy. The character Rena Ryuugu, primarily associated with Higurashi, was originally a heavily-modified fan-rendition of Reina as well.[8] The uniform worn by Reina, a highly modified rendition of the dragoon outfit, would also become the Angel Mort costume worn in-universe by Higurashi characters before becoming emblematic of 07th Expansion as a circle.

Ryukishi's artwork is (in)famous for its poor quality, which initially contributed to early difficulties in Higurashi's growth since it was one reason not many doujin stores wanted to sell it.[9] Ryukishi considered his art style intentional however, wanting to lure readers in with a false sense of security in thinking it was just a romance story.[10] Ryukishi is especially criticized for the way he draws hands, which he is conscious about.[11]


Ryukishi describes his writing process as like building a rollercoaster: he gets readers excited and hopeful with fun and happy scenes before putting in cruel scenes.[12] He enjoys seeing people react to his work, especially if they're horrified.

Ryukishi also thinks of his writing process as like playing a game with the readers. Ryukishi looks up fan reactions to new installments of his work and will change or add parts according to reception; sometimes he'll reference popular fan theories, but other times he'll throw out future plans and rewrite things from scratch, as he did with Umineko Episode 3.[13] When it comes to fan-made derivative work, Ryukishi has shown great support for it.[14]


Recurring themes in Ryukishi's work are social issues such as child abuse and familial relationships, which are seen as realistically written due to his experience as a civil servant.[12]

"One part of my fictional world/character settings are similar, or pretty much borrow the concept of star system, making you feel 'Oh, there is that character!'"

Another recurring aspect is characters with similar appearances and names to those in his prior works. He sees his characters as actors and compared using similar character designs to Harrison Ford playing both Han Solo and Indiana Jones: the person behind the role is the same, but the character they are playing in each movie, or in this case game, are very different.[15]

More recent works produced by Ryukishi have seen the presence of the wanya, a blob-like creature that seems to be his author avatar.


Early Work

Before he started using the penname of Ryukishi07, he was involved with making an 18+ doujinshi, however it saw limited success. The first use of the Ryukishi07 name was for another, "all-ages" doujin.[16] After this, Ryukishi started creating custom cards for the game Leaf Fight, making some based on characters from Tsukihime and the Key visual novels AIR and Kanon.

    Yano: Speaking of erotic, you’ve made an ero-doujinshi once, right? Even if it was an all-ages one, and everyone was with their clothes on, it was more erotic than any 18+ doujinshi.

    Editor: What did you say?!

    Ryukishi: Ah, there was something like that, wasn’t it *sweat* It’s embarrassing, don’t talk about on public, please!

    Editor: When was it released?

    Ryukishi: I think… it was more than 4 years ago. The name “Ryukishi07” was actually made for this. After that, we’ve released 7 original card products for Leaf Fight. We’ve put the most energy around the time we were creating sets based on AIR and Pia Carrot. There were no any titles that were interesting enough to work on after that. And after struggling with what to do next, we’ve decided to make an original product.

    Editor: I bet those who bought that doujinshi at that time couldn’t even imagine that its author would create something like Higurashi.

    Ryukishi: Only 20 copies were sold back then… By the way, I even touched that in a Staff Room a little bit, but before I took the name Ryukishi07 I took part in creating a 18+ doujinshi, though it sold 5 copies at most *bitter laugh*

    "Featherine is the closest thing to a god in that world, the world's guardian. So there's no doubt that she's the strongest character in the story. At the same time, it's pretty embarrassing. I made myself appear in my work and wrote "I'm super strong~!" (laughs) Isn't it like a fantasy novel with the author himself as the strongest hero?"
