“Hareten no delta buoy” production project opens up
“Synthfiction” WEBTOON
WEBTOON is a comic style that originated in South Korea and is optimized for reading on smartphones, but recently, the debut of an original Japanese work has been attracting attention. Among them, the pioneer of WEBTOON in the “synth fiction” genre that Kappi is good at is “Seite no Delta Buoy”.
“Synthetic” is a “synthetic” of “fiction” and “non-fiction”, and it is not a complete reproduction of reality, but a setting based on facts. A new interpretation of the story. Characters modeled after real people create a more dramatic world view. Mr. Kappi and Number Nine are good at this method, and we would like to apply it to WEBTOON and make “synthefiction” a new hit category in the WEBTOON area. -Comment from original author Kappi-
To be honest, I wasn’t sure if WEBTOON’s “work stuff” would be successful, but I thought it might be possible to convey the passion of rocket production because it’s a WEBTOON that involves a lot of professionals. We hope that our rocket will reach many people. – Comment from Mr. Fuwai, who is in charge of naming –
In April 2022, when I actually interviewed Interstella Technologies Inc., my impression was, “It’s already a story like a cartoon.” Passion, growth, failure and success… A hot drama exists as a solid history of the company. thought. I hope that you will see the challenges of the heavens who challenge their big dreams.
– Comment from Mr. Inagawa, President of Interstella Technologies Inc. – Until now, science fiction has been the mainstream of space
entertainment. I believe that this gave many people a dream, and that it had a great significance in promoting the realization of space development. On the other hand, the present point is that the space industry as a real industry will emerge more and more in the future. I would be happy if many people could enjoy and learn about the challenging and exciting environment of the rocket development site. – Comment from Mr. Fujita, CEO of INCLUSIVE Co., Ltd. –
This project was started with the desire that everyone at Interstellar Technologies was moved by the passion of Taiki-cho, aiming for space, and wanted many people to know about it. Feel the new Japanese manufacturing through this hot story!
– Comment from Kobayashi, President of Number Nine Co., Ltd. – The rocket development WEBTOON “Hareten no Delta Buoy”, based on the original work by Kappi, the author of my favorite “Left-Handed Ellen”, has finally started! Interstellar Technologies, Taiki-cho, Hokkaido, and SPACE COTAN backed up the behind the scenes of rocket development, which is not well known! Please take a look at the realistic rocket development ensemble drama that has never existed before!
