After analyzing, I’m pretty sure Tokikaze might kill himself. Eins asked who his murderous intent was geared to, as that’s what controls him. Yet, the mangaka hid his reply. In a writers standpoint, there’s no need to hide something if people already know who it’d be. It couldn’t be Rihito or Schumerman then, as it would have been to obvious. His words with Eins earlier as well show signs of self resentment and regret. Tokikaze must hate himself the most. He blames himself for Rihito, blames himself for his wife’s death, blames himself for his friends’ suicides, blames himself for causing both Rihito and Hina pain. The person his murderous intent is geared to, is himself. After an intense battle with Rihito, he may try to kill himself to prevent from killing either Rihito or Hina.
