I'm really confused and I totally lost the thread of what's going on but my hypothesis is because Aikawa has the most OP power of stealing other people's powers, he's becoming a convoluted mish-mesh of different magic gimmicks like a late stage vampire survivors character, and that's why he has so much going on. Also iirc he's the person that fell in the black sludge of magic before? Making him the titular dorohedoro-man. But that's just a theory.
