Kasumi route: Reinhard never descended into the mortal realm so Merc resets.
Kei route: Reinhard couldnt use his Atziluth or his Gladsheim would crumple, ending the ritual so Merc convinced him to wait another 70 years or so for another time. Merc resets.
Marie route: Reinhard was on the same level as Ren where both are not strong enough to fight Merc. Merc resets.
Rea route: Reinhard finally discovered his true craving and awakened, thus reaching on the level as Merc apoptosis. Ofc Reinhard had to absorb more souls to finally reach his level tho so both killed each other.
