The Time Travel of the Ultimate Ichiban Tai

An 18-year-old boy was bored at home watching Ultimate Class 3. He suddenly felt very sleepy. After a nap, he woke up in another world. He found that he was actually in Ultimate Class 3. He was very surprised. This is something I suddenly wanted to add. Maybe all the plots of Ultimate Class 3 will be broken by my addition, and there are plots from Ultimate Class 2, but I still won't remove the important plots.
