Reborn as Aegon During The Dance!

Mark, a twenty-year-old depressed guy, was walking down the street when he noticed that two school kids were about to be run over by a truck.  He rushes to save them but gets hit instead, dying as the truck tires run over his head, breaking his skull like a watermelon.  But fate gave him a chance; now reborn as Aegon II, son of Viserys, he swore to himself that he would protect his family, his mother, and siblings, and win the Dance of the dragons.  “But how!?”  “Wait…. I can summon Ghidorah!???” Disclaimer: Contains Incest
