Synopsis: Yaritsukai to, Kuroneko

Kagari Shuuya found himself in a sterile white room, where he was given the chance to reincarnate into a new world through a futuristic interface. He boldly chose to become a half-vampire, despite the hindrance of an aversion to light-based magic. However, he overcame this flaw by selecting an extra skill that allowed him to use light magic. This combination gave birth to a new species, the Seivalt. He also selected three other skills: language comprehension, chain projection, and growth modification. With his cheat-like abilities, Shuuya was transported to a harsh alternate world. Despite his impressive advantages, he struggled to survive in an underground society devoid of other people. One day, he faced a gargantuan white-winged monster known as an apostle. The ensuing battle left him badly wounded, but he miraculously transformed into a small black cat and survived. His new form, once revered as a Divine Beast, became his guide in the adventures to come.
