An Apostle is a being born to shoulder an important mission. Apostles born in laboratories are created to give their lives for the evolution of humanity.
After the first batch of Apostles escaped from the laboratories, they went through a period of consolidation before beginning to reproduce on a massive scale, plunging human society into turmoil.
Yu Hua transmigrated from 21st-century China to another Japan, becoming an Apostle who appeared to be a high school student while secretly living among humans.
But Sakurai Hua felt no sense of danger. Instead, he found it all rather interesting. He had little to do with the world of Apostles; what he really wanted was to start a band, copy a few books, and play some music.
The narrative style, characters, and villains are modeled on Kamen Rider. If you like that, come take a look.
