Hikawa Profile
The man responsible for the Conception and leader of the Council of Nihilo (a group of demons, mainly conformed of the Fallen, Vile, Night, Femme and Tyrant clans), he brought the "end of the world" by summoning the Demons to the world . He has his Reason from the very beginning which which is the idea of a world of stillness, a world where history is still: the world of.
By using the Maiden (Yuko) he first tries to collect Magatsuhi slowly, and uses the Nightmare System as a way to destroy any opposing Reasons (until it is deactivated by the Demi-Fiend). Then he decides to sacrifice the Maiden herself on the Diet building, where a large amount of Magatsuhi is stored so he can summon his God.
Regardless of the protagonist's Reason, Yuko is sacrificed and Hikawa's God is summoned: Ahirman. It is not long until they meet again at the tower of Kagutsuchi since Ahirman decided to wait for the Demi-Fiend to arrive before he climbed it. If he is with him, fine but if they have different Reasons they battle to death. Ahirman at first looks like a simple shell, but after battling for some time, Ahirman decides it is time to finish their little "game" and shows his true form, that of a gigantic and extremely powerful demon whose's simple movement of his back wings is powerful enough like to wipe out any weak demon. The Demi-Fiend barely comes out victorious, Ahirman's head shatters revealing Hikawa, who is shocked by the power of the Demi-Fiend, saying it all so quiet...
If he was with him, Hikawa then understands that he never was supposed to be the one to create the new world, that he simply was a step on a stair to allow the Demi-Fiend to do so.
Game of appearance: Shin Megami Tensei : Lucifer's Call.
