Is your character any manner of spirit, youkai, demon, or otherwise inhuman being? Does your character share their body with any manner of spirit, youkai, demon, Persona, etc? Ain is an angel! And he's usually lying and saying he's a priest and that he's human... but he is Very Much An Angel.

If your character is human, is your character capable themselves of sensing spiritual energy, youkai, demons, etc? Further, do they have harnessable spiritual powers? Not human, but - Ain CAN sense spirits/demons/etc. His magic is his spiritual power, so yes to that. It's a complicated system to explain, it runs on what's called "cycle magic" but a lot of his power is tied to his emotions nowadays. TL;DR if Ain casts magic it's very much like "whoa that's some angel shit you're doing there buddy". Please let me know if you have questions bc Elsword canon is horrible to explain I'm sorry—

Does your character carry any manner of object or artifact that might ping as being related to spirits, demons, the underworld, etc? His pendulum might ping. It's bound to him and he can break it to increase his magic, mostly he uses it as an arcane focus though. The pendulum is said to regenerate if he breaks it. He will probably not do this or he's just going to be completely fucking unfettered at all times. Or maybe he will 👀

Are you okay with Matoba sensing your character's inhumanness/their ability to see/their magical or spiritual artifact? YES

Are you okay with Matoba testing your character's inhumanness/their ability to see in minor ways (such as asking intrusive questions/making references to things that require special perception/using magic on surroundings to see if they sense it? YESSSS please call him out on his bullshit I'm begging
