Long Yan was brought to the world of Kamen Rider King by the system to sell a kind of chip, which is the power of monsters and humans in the Ultra World.
The system gave a transformer, but it was Tiga who transformed into a mask. The chips were obtained by going to the Ultra World in the dungeon. From then on, Long Yan started selling chips.
