The Extra's Harem Is Full Of Yandere

[Warning: mature content~]



Vincent Takahashi, a lone introverted nineteen year old boy would never have thought he could be reborn in the world of his favorite book after an encounter with a goddess.



Being a crazy follow up fan of the MC, Vincent tried to keep him alive with the extensive plot armor of future referencing in check.



However, he soon realizes that the original plot of the novel was changing due to the decisions he was making as an extra leading to the emanation of villainous characters that were never in the original plot.



With sheer luck, his harem of yandere girls might as well become his ultimate armor.
