A Viking Boy's Infrastructure-Building Diary

A young Viking chieftain unexpectedly returns to the past and gets a phone with a chat group that can connect to other dimensions.

“Ding-dong! The Savior of Tokyo, the little Grim Reaper detective, has joined the chat group.”

“Ding-dong! The one and only, the cat-like Gojo, has joined the chat group.”

“Ding-dong! The timid, death-fearing Demon King has joined the chat group.”

After talking with all these fascinating people, the young Viking boy gained a wealth of knowledge. He looked at his homeland, the Viking islands, then thought of his dragon. A plan quietly took shape in his heart: he would turn this place into a homeland where humans and dragons could live together in peace!

Many years later, his Dragon Clan Archipelago Empire stood tall across the entire ocean. Merchants came and went without end, and life for both the people and the dragons was thriving.

He was the Viking chieftain and the king of this island empire. At the king's side was the supreme Dragon King, Toothless! Together, they ushered in an era of peaceful coexistence between humans and dragons and created a legend that would never fade!

Original setting: Toothless will eventually develop humanlike thoughts and take human form. Read the story to find out why.

In a nutshell, it's the story of a young Viking chieftain who, with help from people in other dimensions, builds the Viking Islands into a maritime empire! I hope you enjoy it!
