As promised, the game was a standard poker game. Even before the hand was dealt, Arthur felt the mana swirl in the surrounding. Everyone was using their abilities.
As he sat there studying the players, Arthur noted a couple of things in his mind. To win this game, you need to be preceptive of who's using mana and who's not. Another aspect was that you need to know the opponent's ability.
Nera and glasses girl didn't know that he had a clue about their identity. As for Rae, she was glaring at him in such a way that he knew she would bite him if she had the chance. He doubted she would care if Arthur knew her ability or not.
To begin with, Arthur didn't know how would she win using her ability. As far as he could tell, her ability was mainly combat-oriented. However, that didn't exclude the possibility of her ability having other uses or that she had skills.
