[Danganronpa/spell Return] I Broke the Defense by Dressing as My Own OC

I broke my defense Not because of anything, but I've traveled through time. It would be fine if I traveled to other places, but this is Danganronpa, and I have only watched the anime. Just when I thought I was about to die, I saw the normal Hope's Peak Academy Great! I am from the class of 1977! So, please give me some advice. I am a super high school-level firearms designer, Qing Shuiyuan! Wait, you told me the world merged? Is the world full of cursed spirits now? Isn't this the world of Danganronpa? My sister Bai Yueguang, who died young, has become a cursed spirit? That guy with pink hair and white hair, you are on the wrong set! Concept: Sunny and cheerful little sand sculpture
