If Issei has both Great Red's and Ophis DNA's on his body i don't see the problem in classifying them as his dragon parents. Remember that a human is bound to his parents by DNA not his soul. His soul only tells us he was human before, but being brought back by Great red fleash and ophis powers made him a part of them, even Shiva tells issei that they're his second parents. So in my opinion i dont see why they shouldn.t be classified as his second parents when even the main character himself sees them that way. Remember this is my opinion.
