My Big Spring Thing Really Has a Fire Shadow

My name is Hikigaya Hachiman, and I was an inconspicuous high school student. Why do you say "before"? Of course that was the fault of that idiot Naruto, he always did that every time he took charge of my body. . . Stupid! By the way, Naruto, did you come together in a group? The guy named Sasuke ran to Hayama, and then... Even the snow cave was possessed by the fox named Jiu Xiao. ....... Indeed, it is not normal to take turns taking charge of the body with these guys from another world, but it is quite interesting once you get used to it... But what the hell are the five monsters in front of me! Why is my body shining with golden light... Wait, what are those black balls? Why do you still seem to be targeting me?
