The daily life of the final class of Guava High School was broken by a golden light from the sky - a mysterious man fell from the roof and lost all his memory, leaving only a "flame core pendant" with flame patterns engraved on his neck and made of unknown material. Jin Baosan named him "Yan Zhen", and this taciturn transfer student joined the ultimate class full of superpowers and passion.
There are too many mysteries hidden in Yan Pendant: he can trigger the light red flame ability in times of crisis, and the source of his power seems to be closely related to the flame core pendant around his neck - when the pendant heats up, he will flash fragments of broken memories (the rotating light hole, the pursuit of the man in black), and the combat power index will also fluctuate accordingly, but he can never control it. In order to protect this special partner, Wang Dadong, Lei Ting and others helped him adapt to campus life while secretly investigating the origin of the flame core.
However, a man in black who calls himself the "Observer of Time and Space" suddenly appears, pointing out that the Flame Pendant and Flame Core Pendant are "hidden dangers that disrupt the order of time and space" and wants to take him away by force. Facing the unknown threat of time and space, Yanzhui, with the support of his ultimate group of partners, began to try to control the restless power in his body while pursuing the forgotten past. Who is he? Why does the flame core pendant coexist with him? What kind of crisis will the "time and space rift" mentioned by the people in black bring? This adventure about memory, abilities and bonds has just begun in the classroom of Ultimate Class 1.
