Stupid Test: How Could I Be a Vampire?

Tsujimu Tsuji, as a weak and sickly boy, did not study at his adoptive father's Black Lord Academy like his elder brother. Instead, he chose Bunzuki Academy, which was established in recent years. Bunzuki Academy has an experimental summoning war system that has attracted much attention in the world. It will be super interesting here. Here, he had his own friends, and in the second year, something more interesting happened. Regarding this, Tsujimu Tsuji just wanted to say, I am really not a vampire! ! ! (It has certain movie-viewing elements, but the elements are not strong.)
