In Reincarnated as a Slime, when Myulan is exploring Rimiru city, why did a dragonewt stop to stare at her?
Well about that those races of dragonewt's can sense powers if they focused on they're surroundings so he just found that there was a majin and was thinking maybe that she might be related to the other majin's in the vincity and he saw her confused but not as a threat that would destroy the magic in the surrounding.
For example take the dragonewts leader's sister she wanted to join as an assassin with a majin.
So they might be used to they're vibe and saw her with the same vibe.
