Realizing how the two are preparing for their death, Alros decide to end this as quickly as possible. Demonic aura unleashed, as the dark and wicked aura slowly pressed on the two B-rankers.
Slowly, the aura the two have were overwhelmed, as they are used back, their exhausted breathing showing how tiring it is to keep such might for a long time.
However, they did not stop, planning to sacrifice themselves. Without the demon, or with him being badly injured, some of their force could run away and report what happened, ensuring the monster's identity will be revealed.
Of course, Alros noticed this, and he did not plan on letting two of his greatest prize and future possession to die so easily. Using his power, he easily reached for the two throats, both of the B-rankers unable to do anything else on the account of using their greatest strength in an attempt to weaken the demon, allowing them to do the final kill.
