Implosion Spinoff: Haru is a Part-timer in Different Worlds

Summary: What if Arata Shouta/Adam/Harukin/Sun-kun/Aelius reincarnated normally in wonderful world. How can he survive his new Isekai life? The cover is not mine, pm me if you are the owner, I'll immediately take it down. I'm just writing this fanfic to train my English proficiency. I will only upload a chapter if I want to. This is my third time writing and English is not my first language so forgive me if I made a lot of mistakes in my grammar.
