Number of Volumes
An angel made a mistake, resulting in Shiihara Daiki’s death. In order to hide the mistake, he was then sent to a different world. The angel will grant him one wish as a payment for keeping it a secret. Daiki asked for a Heavenly Castle floating in the sky without hesitation.
Suddenly a floating castle appeared in the new world, which causes confusion amongst the people. They attempt to contact Daiki in various ways. A country tries to steal it by force, while another seeks to befriend him. What in the world would Daiki do?
I really like this series, the manga was pretty good. Good bit of adventure and fantasy with a bit of a sci-fi twist with mechanised golems and a very sci-fi like castle. The only problem is that this series might be stalled or cancelled since it hasn't had a new volume since 2019.
Here's the illustrations for volumes 2 + 3
Worth noting that the title is stalled/cancelled.
Light Novel retailers never list stuff as completed/stalled/axed without the publisher telling them so. Otherwise, the volume 3 listing is for the manga adaptation. The Light Novel's third volume came out back in 2019.
Whether the Web Novel is ongoing doesn't really matter if the publisher dropped releasing the Light Novel.
