He was, however, now very aware of what she was implying. His tail twitched behind him before he got it under control and tucked it back further against his back. "I'm not a card. I'm not a creature you can lock away and summon at will. I'm not even supposed to be a monster at all!" His right eye flashed with an odd glow briefly before he (more) calmly continued. "I was human once, before a different place similar to this train nonsense stole me and turned me into an arachne. And now I'm here with the rest of the people."
