Speaking of the origin of the original cooperation, in 20 14, Gen Urobuchi came to Taiwan to attend the signing ceremony of the Taipei International Animation Festival, and visited the' Fantasy Martial Arts World of Thunderbolt' which was also exhibited at the Animation Festival in that exhibition. This was the first time that he realized the puppet show of Thunderbolt. According to Gen Urobuchi himself, it was a "great shock". He went back to Japan and watched it on DVD.

Besides, Gen Urobuchi is not just putting on a show. He even sent a tweet while watching the DVD he brought home, shocked by the sudden death of a character, Li Bai Bin Hong.

Huang Liangxun is also one of Gen Urobuchi's fans. Someone paid attention to his Twitter, discovered Gen Urobuchi's enthusiasm for puppet shows, and contacted Gen Urobuchi again, expressing the possibility of cooperation between the two sides. So Gen Urobuchi flew to Taiwan Province Province again to discuss the matter with them, and his response was quite positive in the process, so the two sides confirmed their willingness to cooperate.
