Cap 1276: Detective Zenos part 3

I was inside a hotel room with a body on the floor, the corpse had a distorted smile on its face. 

"Are you sure you can trust him?" (I) 

"Yes, he is an old acquaintance, one of my subordinates, if he chose to make a contract, I don't believe that this person is bad." (Byakko) 

"What did you think of him Kira?" (I) 

"He hid his presence very well and set up several traps around me without me noticing, he also pretended to have several openings in his posture to make me attack him, he also hid his true strength by pretending to be someone of the same level as me." (Kira) 

"You said he uses a Spear as a weapon, which is also his Contracted Spirit, so I can imagine his way of fighting." (I) 

As someone who created games, the biggest problem was always the story and how this was reflected in the mechanics of both main and secondary characters or even NPCs.
