you had defeated Megumi fushiguro who was injured and couldn't do much to defend himself, when you were going to kill him, Megumi would extend her arms and say

Megumi: With this treasure I summon you!

out of nowhere a huge female figure would appear which would hit Megumi very hard and leave him unconscious, upon seeing this you would look at the female figure and see that it is Mahoraga...

Mahoraga walks slowly towards you and would be ready to attack you!!
