Meng Fan was an Ultraman suit actor. When an explosion suddenly occurred during an indoor shoot, he turned into light and transmigrated to Blue Star, a high-tech world where martial arts reigned supreme.
Humanity's exploration of outer space drew the attention of the Sphia lifeforms, causing Sphia fusion monsters to appear all over the world. Fortunately, humans could fight back with Monster Armor.
But Qin Lan, whom everyone had pinned their hopes on, received a Spark Lens when she was matched with Monster Armor, and it was registered as an invalid weapon.
When the monster Bemstar attacked, Qin Lan successfully formed a bond of light with Meng Fan and transformed into Tiga.
From then on:
Qin Lan: I'll protect the world.
Meng Fan: I'll protect you.
