Highschool DXD X Busou Shoujo Machiavellianism Crossover Challenge
We all know that Issei had a normal family before he was turned into a devil. But what if that was a lie? What if Issei was only their adopted son? Before Raynare can kill him, a woman saves him using incredibly advanced martial art skills. After passing out and being carried home, Issei wakes up the next day only to discover the same woman in his house. There he learns that he was adopted and the woman's name is Kirukiru Amou and (even more shockingly) that she's his biological mother. Reunited with is real mother, Issei sets out to learn the whereabouts of his real father Fudou Nomura. Also what did Amou mean by meeting his three step-mothers (Rin, Mary and Satori) and his step-siblings?
NB:
To clarify, after graduating their respective academies, Amou gives birth to Issei a few years later, but due to the enemies she has made, Amou was forced to abandon Issei as a newborn to keep him safe.
Nomura is the kind of guy who can't stay in one place for long, so he moves around a lot.
Polygamy is not legal in Japan, but it is not uncommon to take a concubine. You will have to choose who will be the wife.
Issei must be a little les perverted or at least able to temper his lust.
Warabi Hanasaka and Tsukuyo Inaba do not have any feelings for Nomura. Warabi is Nomura's friend while Tsukuyo is his teacher.
Non-Devil Issei (Amou will not be happy knowing the fact that her son is someone's servant.)
Issei can use a martial art style (OPTIONAL)
I'm not up to date on the manga was the sites have not updated it. So if I missed or forgot to add any, please forgive me.
