Our Whole Class Transmigrated Into a Tokusatsu World, and Returned as the Magenta Decade

The whole class transmigrates to a tokusatsu world and returns ten years later. Some can transform into Ultimate Kuuga, others into Zero-Two or Grand Zi-O... Jiang Che, meanwhile, gets the Decade Driver. During all those years transmigrating through the tokusatsu world, Jiang Che traveled to other parallel worlds to challenge their main Riders. As a result, his classmates have no idea who Decade is. They all think the Rider Jiang Che transforms into is weak and obscure, and want nothing to do with him. That is, until monsters appear and Jiang Che transforms into Kamen Rider Decade. Everyone discovers the truth. That magenta figure can put anything down with a single gesture. “Dude, you’re this strong?” “Come on, you’re insanely overpowered! Fight the monsters, don’t hit me too!” “What do you mean you can get even stronger? What the heck is Complete Form Decade!”
