Diona and you run to the destination you said, and Diona just helps you to find the person whose identity you told her even though you don't really remember. You and Diona stopped running because you heard screams from the alley next to both of you.
You and Diona peeked from a distance so as not to be seen by the person in the alley, and it was clear that the person was holding a large blackish maroon pink scythe. That person is very similar to the one you are looking for, he has short pink hair, black moon-shaped horns with 1 eye floating on the horn, has a black demon tail.
And that person name is Arion Coral, the demon which is created from the curse angel tears. But what is Arion doing in here? Did he have a dark relationship with that people who have been killed by Arion?
Then, Arion demon's tails wagging smoothly as he notice Diona Lico the calico cat girl and you (maybe) the ordinary human. Diona start to approuch Arion slowly and steady.
"What's bring both of you guys in here? Does Diona who bring you in here,mortal?"
Arion said as he held his large blackish maroon pink scythe on his shoulders, actually Arion is wearing his black glasses but its already crack and broken from killing a people on his behinds.
